About us
GRIT LEADERS is an SEO and link building agency working mostly in iGaming. We serve operators and platforms worldwide: guest posts, PBN links, brand protection, technical SEO, content. We're expanding the sales team and adding an SDR to our team — you'll have processes and people to lean on, plus real room to shape how outbound works here.
 

What you'll do

• Build target lists around our ICP: operators, affiliates, media buying teams, agencies
• Run outbound across LinkedIn, email and Telegram — write, follow up, keep the thread alive
• Qualify leads: is there a real need, who decides, is there budget
• Book meetings for our Account Executives and hand over leads with actual context, not a single line
• Keep every lead and interaction logged in Pipedrive — if it's not in the CRM, it doesn't exist
• Research the market: who just entered a new geo, who changed vendors, whose visibility dropped (Ahrefs, LinkedIn, industry media and chats)
• Attend conferences across Europe: fill your calendar before the event, collect contacts, follow up after
   

What we're looking for

• English B1+ — you'll write in it daily and talk to people face to face at events. We test this in the interview
• 6 months to 2 years in lead generation, outbound or sales — industry background is not critical but iGaming is a plus
• You can dig for information and draw a conclusion from it, not just paste it into a spreadsheet
• Proactive: you show up with hypotheses and questions instead of waiting for step-by-step instructions
• Organised: your data, notes and next steps stay in order without someone chasing you
• Valid international passport and readiness to travel to European conferences regularly (2–4 times a year)
   

Nice to have
 Experience in iGaming or in SEO/link building. CRM experience (Pipedrive, HubSpot). Apollo, Sales Navigator, Ahrefs.
 

What we offer

• Remote, flexible hours with overlap with the team
• Conferences and travel covered by the company
• Onboarding, internal knowledge base, call and email reviews — asking a lot of questions is expected here
• A clear path to Account Executive: your own pipeline, your own deals, commission. This is the default trajectory for the role, not a vague promise
   

Hiring process
 Screening → short practical task →  interview with Head of Business Development

Data Science UA is a service company with deep expertise in AI and Data Science. Our story started in 2016 with the first Data Science UA Conference in Kyiv, and since then, we’ve built one of the largest AI communities in Europe.

About the client

Our client is developing technology to make industrial environments safer and reduce the risk of accidents through proactive monitoring.

The Ukrainian engineering team is building a next-generation industrial safety platform combining Computer Vision, Machine Learning and IoT.

About the role

We are looking for a Middle Systems / Software Engineer to work on the performance-critical core of a real-time Computer Vision platform.

This is not a typical Python Backend role. The main challenge is building and optimising the systems underneath the CV/ML engines — where performance depends on memory, processes, concurrency, data movement, CPU/GPU utilisation and low latency.

You will work on the runtime that executes CV pipelines as a graph of processing stages, with latency measured in milliseconds. You will deal with shared memory, zero-copy data transfer, inter-process communication and process orchestration.

What matters most to us

We are open to engineers coming from C++, Python, Go or similar backgrounds.

The programming language itself is not the main selection criterion. What matters much more is a strong systems engineering mindset and experience understanding what is happening inside a system.

For example, we are particularly interested in engineers who have worked with problems such as:

• reducing unnecessary memory copies;
• optimising CPU/GPU utilisation;
• investigating latency spikes and performance bottlenecks;
• working with processes, threads and concurrency;
• debugging race conditions and difficult low-level issues;
• profiling applications and identifying bottlenecks;
• designing efficient data-processing pipelines;
• working with large amounts of data moving through several processing stages;

• optimising algorithms or runtimes for performance.

   

A candidate does not necessarily need to have worked with exactly the same technologies before.

For example, experience with CUDA, C++, GPU optimisation, real-time processing, robotics, computer vision, video pipelines, scientific computing or other performance-sensitive systems can be highly relevant.

What you’ll work on

• Collaborate with CV/ML engineers to turn model inference code into reliable production pipeline stages.
• Develop and optimise the core Pipeline Engine — an in-process, real-time runtime executing the CV pipeline as a graph of stages.
• Work with zero-copy shared-memory pools for passing frames between processes.
• Develop and optimise low-latency ZeroMQ communication for control messages, metadata and synchronisation.
• Work with pipeline metadata and serialisation boundaries.
• Analyse and improve CPU, memory and latency performance.
• Profile, debug and troubleshoot complex runtime issues.

• Contribute to the architecture and evolution of the real-time processing infrastructure.

   

Requirements

Must-have

• Commercial experience as a Software Engineer / Systems Engineer / C++ Engineer / Python Engineer or similar.
• Strong systems engineering mindset and understanding of:
  • processes and concurrency;
  • memory ownership and data movement;
  • latency vs throughput trade-offs;
  • performance bottlenecks;
  • profiling and debugging;
  • failure modes of complex systems.
• Experience working with performance-sensitive or latency-sensitive systems.
• Experience with at least one of C++, Python, Go or a similar programming language.
• Python is used in the platform, but it does not need to be your primary language. Strong C++ / systems experience is equally relevant.
• Solid Linux fundamentals.

• Solid experience with Docker and containerised environments.

   

Nice-to-have

• CUDA, including IPC handles and stream synchronisation.
• C/C++ or Go.
• OpenCV.
• GStreamer, FFmpeg or RTSP.
• ZeroMQ.
• Shared memory / zero-copy architectures.
• FlatBuffers or other binary serialisation formats.
• Experience building or operating camera/video pipelines.

What we offer

• Competitive compensation.
• Benefits package.
• Strong engineering team.
• Opportunity to work on challenging real-time Computer Vision infrastructure.
• Meaningful industrial safety use case.
• Technical challenges and opportunities for professional growth.

About Project

It is a mobile accounting app for sole traders, freelancers and self-employed workers — income, expenses and tax handled from a phone in minutes rather than evenings.

Every year, hundreds of thousands of self-employed people type "can I claim my phone bill" into Google and land on something written by a content farm, out of date, or aimed at accountants rather than at them. Being the clearest, most accurate answer to those questions is one of the most durable growth assets this business can build — and it compounds while paid channels don't.

The job in one line

You own our written content: what we publish, why, whether it's accurate, and whether it brings us users.

What you'll do

- Own the content strategy and calendar. Build it around real search demand and real user questions, not topics that sound good. Publish to an agreed cadence (4–8 substantial pieces a month) across blog, guides, landing pages, email.
- Win high-intent search. Research and prioritise keywords around allowable expenses, Self Assessment, VAT, deadlines, sole trader vs limited company, and the specific trades and professions we serve. Own on-page SEO, internal linking, content refreshes and technical basics in partnership with Engineering / an SEO consultant. 
- Meet the accuracy bar this subject demands. Tax content is exactly what Google treats as "your money or your life" — it needs demonstrable expertise, named authors, review credits and current dates to rank at all, and it needs to be right regardless of ranking. Every piece touching tax rules, thresholds or figures goes through [our accountant / compliance sign-off] before publishing, and gets re-checked each [April] when rates change.
- Build the deadline content machine. 31 January Self Assessment, the 5 April year end, quarterly VAT/MTD deadlines and the April Budget changes are our peaks. The January content set is written, reviewed and live by November, not drafted in January.
- Own lifecycle and in-product copy. Onboarding emails, activation and re-engagement sequences, deadline reminders, release notes, app store listing copy, plus in-app microcopy in partnership with Product. Measured on activation and retention, not on open rates alone.
- Run the writers. Brief, commission and edit freelance writers and subject-matter contributors [budget: specify], and hold a consistent editorial standard and tone of voice across everything we publish.
- Set the tone of voice. Write and maintain the style guide — plain English, no jargon, no scaring people about HMRC, no condescension about money. Everyone else in the company writes to it.
- Supply the other channels. Turn each substantial piece into raw material for social and creator briefs, and maintain the guides, checklists and templates that Support and Sales send to users.
- Report honestly. Organic sessions and rankings, content-attributed sign-ups and paid conversions, email-to-activation rates, and which pieces earn their keep. Retire or rewrite what doesn't.

 What we're looking for

- 3+ years in content marketing or editorial for a B2C or SaaS product, with responsibility for results rather than output volume.
- Excellent native-standard written English, and the ability to make a dull technical subject genuinely clear. Portfolio of published work required.
- Practical SEO competence: keyword research, search intent, on-page optimisation, content refresh strategy, and comfort in GA4 / Search Console / Ahrefs / Semrush.
- Editing experience — you can improve someone else's draft and give feedback a freelancer will accept.
- Numerate, precise, and willing to check a figure rather than assume it. You'll be corrected by an accountant regularly and won't take it personally.
 

Nice to have

- Experience writing about UK tax, accounting, payroll or personal finance — or an AAT / bookkeeping background.
- You are or have been self-employed, freelance or a sole trader.
- Lifecycle email experience in a real tool (Braze / Customer.io / Klaviyo / Intercom).
- ASO / app store listing optimisation.
- Comfortable in a CMS and with light HTML; experience with a headless setup.
- Experience building a content operation from a standing start.

About Project

It is a mobile accounting app for sole traders, freelancers and self-employed workers — income, expenses and tax handled from a phone in minutes rather than evenings.

Nobody downloads an accounting app because they saw a banner ad. They download it because someone they already listen to said "this is what I use, and here's why my January was painless this year." Recommendation is how this category grows.

The job in one line

You build and run our creator programme: find the people our users already trust, strike deals that pay for themselves, and prove it in installs and paying subscribers.

What you'll do

- Build the roster. Find, pitch and sign creators whose audience is self-employed: freelancers and creatives, side-hustle and gig-economy channels, online sellers, tradespeople, small business and personal-finance creators, and accountant/bookkeeper creators. Target: 30+ active partners in year one, weighted toward mid- and micro-tier where trust and conversion are highest.
- Own the commercials. Negotiate flat fee, affiliate/revenue-share or hybrid deals, manage the creator budget line, and defend it with numbers rather than screenshots of view counts.
- Run the tracking properly. A unique code or deep link per creator, attributed through to install, sign-up and first paid subscription (AppsFlyer / Adjust / Branch or equivalent), with monthly payout reconciliation agreed with Finance.
- Own the numbers. Cost per install, cost per paying subscriber, code activation rate, 90-day retention of creator-sourced users, and blended payback period. Weekly reporting, and the discipline to end partnerships that don't convert — including ones with impressive audiences.
- Brief, don't script. Give creators the message, the proof points and the boundaries, then let them say it in their own words. Reject anything that reads like an ad script — this audience switches off instantly.
- Keep every claim safe. Every partnership disclosed to ASA CAP Code standards. Every statement a creator makes about tax, allowable expenses, refunds or deadlines checked against our accountant / compliance sign-off before it goes live, and corrected fast if it slips through. A creator giving wrong tax advice on our behalf is our problem, not theirs — you own preventing that.
- Amplify what works. Identify the best-performing creator content and put paid budget behind it with usage rights agreed up front ([TikTok Spark Ads / Meta partnership ads]), rather than commissioning new content every time.
- Plan around the calendar. 31 January Self Assessment, the 5 April year end and quarterly VAT/MTD deadlines are when this audience is actually thinking about tax. Creator slots for January are booked in October–November, not in January.
- Feed the business. Report back the objections, language and misconceptions you see in creator comments and DMs — it's the cheapest product and messaging research available.

 What we're looking for

- 3+ years running influencer or creator campaigns with commercial accountability — you've held a budget and been measured on installs, sign-ups or revenue, not reach.
- Hands-on experience with affiliate or referral tracking and creator payouts — you've built the tracking and reconciled the payments yourself, not just handed it to an agency.
- Real negotiation experience: you know what a creator is worth, what to walk away from, and how to structure a deal that shares risk.
- You understand the UK self-employed audience well enough to judge whether a creator's followers are actually our users, or just a large number.
- Written English clear and personable enough that creators reply to your first message.
- Accurate and cautious with claims about money and tax — you check before you approve.
 

Nice to have

- Fintech, accounting, tax or personal-finance product experience.
- Existing relationships with UK freelance, business or finance creators, or with talent agencies.
- Experience with app install attribution and mobile measurement specifically.
- Paid amplification of creator content (Spark Ads, whitelisting, usage rights).
- You are or have been self-employed or freelance yourself.
- Experience scaling a referral or affiliate programme.

About Project

It is a mobile accounting app built for people who never wanted to do accounting: sole traders, freelancers and self-employed workers who need their income, expenses and tax handled from their phone in minutes, not evenings.

Our users aren't finance professionals. When something doesn't add up, it's their own money and their own tax return on the line — so support isn't a cost centre here, it's the product. A calm, accurate answer within minutes is the difference between a user who renews and a one-star review.

The job in one line

You own the support function: every conversation a user has with us, the systems behind those conversations, and the numbers that prove it's working.

What you'll do

- Run the front line. Own in-app chat, email, app store reviews and social DMs. Target: first response under [1 working hour] in business hours, 90% of conversations resolved without escalation.
- Hit and defend the numbers. CSAT ≥ [4.5/5], contact rate per 100 active users trending down quarter on quarter, app store rating ≥ [4.5], median resolution time inside [4 hours]. Weekly reporting, no vanity metrics.
- Build the self-serve layer. Write and maintain the help centre, in-app guides and macros so that the [top 20] recurring questions stop becoming tickets at all. Deflection is the main lever once user numbers grow.
- Hold the advice boundary. You explain how the app works, what a figure means and where it came from — you do not give tax advice. You'll own the escalation path to our qualified accountant [/ partner practice] and the standard wording that keeps us on the right side of that line.
- Bridge to Engineering and Product. Reproduce and triage bugs properly (steps, device, app version, screenshots), escalate with severity that means something, chase to resolution and close the loop with the user. Bring Product a monthly digest of the top pain points with volumes attached — not anecdotes.
- Handle peak season. Late January Self Assessment, the 5 April year end and quarterly VAT/MTD deadlines produce spikes several times normal volume. You plan cover, prepare canned responses and staffing before they hit, not during.
- Protect user data. Verify identity before discussing an account, handle personal and financial data under UK GDPR, and escalate suspected data or security incidents immediately per our process.
- Rescue accounts. Spot users about to churn or asking for refunds, and turn what you can around. Report honestly on what you couldn't.
- Write the playbook. Document the process as you build it — SOPs, escalation matrix, tone-of-voice guide — so the next two support hires can be onboarded in days, not months. You'll hire and lead them within 12 months.

What we're looking for

- 3+ years in customer support for a consumer app or SaaS product, including at least 1 year owning metrics rather than just handling tickets.
- Hands-on with a support platform (Intercom, Zendesk, Crisp, Freshdesk or similar): macros, help centre, automations, reporting — you've configured it, not just typed into it.
- Numerate and comfortable around money: invoices, expenses, VAT, tax deadlines. You don't need to be an accountant, but you must not be nervous about numbers.
- Written English that is clear, warm and plain — you can explain a tax figure to someone in a van at 7am without jargon or condescension.
- Calm under pressure with upset users, and honest when we've got something wrong.
 

Nice to have

- Experience supporting a fintech, accounting, payroll or tax product.
- AAT / bookkeeping study, or practical experience with HMRC Self Assessment, MTD, VAT.
- Built a help centre or support function from scratch.
- Mobile-specific support experience: app store review management, release cycles, device-level debugging.

Reports to Head of Marketing / CMO
About project: 

It is a mobile accounting app for sole traders, freelancers and self-employed workers — income, expenses and tax handled from a phone in minutes rather than evenings.

Our audience isn't looking for accounting software. They're looking for an answer to "can I claim this?" at 11pm in January. That's the moment we have to be present in, and social is where it happens.

The job in one line

You own our social channels end to end — strategy, content, production, community — and you're measured on app installs and paying users, not on follower count.

What you'll do

- Own the channels. Run TikTok, Instagram, YouTube Shorts, Facebook, LinkedIn, Threads/X — the mix is yours to argue for and prove. Publish consistently to an agreed cadence, 4–6 pieces per week minimum.
- *Make the content yourself. Script, shoot, edit and caption short vertical video (CapCut / Premiere), plus static and carousel formats (Canva / Figma). This is a hands-on role: we're not big enough for a production team, and briefing an agency for every post won't work.
- Turn tax into something watchable. Plain-English explainers, "expenses you're probably missing", deadline countdowns, myth-busting, before/after of a messy year of receipts. If it sounds like an accountant wrote it, it doesn't ship.
- Own the calendar around real dates. 31 January Self Assessment, the 5 April year end, quarterly VAT/MTD deadlines and April tax-change announcements are our biggest moments of the year. Plan and produce for them weeks ahead, not in the week itself.
- Run the community. Reply to comments and DMs in our voice, and know where the line is: product and content questions are yours, account and money problems get handed to Customer Support within 1 working hour with context attached. Never resolve someone's account issue in a public comment thread.
- Get facts right, and get them checked. Anything about tax, allowable expenses, deadlines or figures goes through our accountant / compliance sign-off before publishing. Any paid, gifted or affiliate content is disclosed to ASA CAP Code standards. We don't publish savings or refund figures we can't substantiate.
- Work with creators and users. Brief and manage micro-creator collaborations [if in scope], collect and repurpose UGC and reviews with permission, and build a pipeline of real user stories.
- Report on what matters. App installs and store-page conversions attributed to social, cost per install, saves and shares, sign-up-to-paid conversion from social traffic, comment sentiment. Follower growth is context, not a target. Weekly numbers, monthly what-worked-and-what-didn't.
- Feed the rest of the business. Comments and DMs are the cheapest research we have — report recurring questions, objections and feature requests to Product and Support.

What we're looking for

- 3+ years running social channels for a consumer brand, app or SaaS product, with commercial accountability — you've been measured on conversions or installs, not reach alone.
- You personally shoot and edit short vertical video to a publishable standard. Portfolio or channel links required.
- Native-standard written English with a genuine feel for tone: plain, warm, funny where appropriate, never patronising about money.
- Comfortable with numbers and with a subject where accuracy matters — you check before you post.
- Hands-on with analytics: platform insights plus GA4 / app attribution to connect posts to installs.
- Close enough to the UK market to understand the cultural references our audience uses.

Nice to have

- Fintech, accounting, tax, payroll or personal-finance content experience.
- You are or have been self-employed, freelance or a sole trader — you'd be your own target audience.
- Paid social experience (Meta / TikTok Ads Manager).
- Creator or influencer partnership experience.
- Community management in Facebook groups, Reddit or Discord.
- Scheduling and reporting tools (Later / Buffer / Metricool).

About the Project:

It is a mobile accounting app for sole traders, freelancers and self-employed workers — income, expenses and tax handled from a phone in minutes rather than evenings.

Behind a simple app sits the complicated part: bank feeds that stop syncing, receipts that scan wrong, subscriptions that don't renew, a figure that's off by £40 and nobody can say why. That's your side of the house. When a user's tax number looks wrong, someone has to prove what actually happened — in the data, not in the conversation.

The job in one line

You are tier 2: everything customer support can't resolve stops with you, and everything Engineering shouldn't be interrupted by stops with you too.

What you'll do

- Own tier-2 escalations end to end. Take what front-line support can't close, investigate it properly and either fix it, work around it, or hand Engineering a ticket they can act on immediately. Target: [90%] of escalations resolved or reproduced within 1 working day.
- nvestigate in the data, not by guesswork. Read logs, trace requests, query the database (read-only SQL), check API responses and reconcile what the app displayed against what was actually recorded. Every escalation you pass on carries a clear reproduction path and evidence.
- Run bank feed and integration failures. Open Banking connections drop, banks change formats, tokens expire, third-party providers have outages. You own diagnosis, the vendor conversation, and the honest message to affected users.
- Triage mobile crashes and releases. Monitor crash and error reporting, spot regressions after a release before the reviews do, and verify fixes on real devices across iOS and Android versions.
- Own billing and store issues. Failed payments, App Store / Google Play subscription problems, duplicate charges, refunds, entitlement mismatches — resolve them and reconcile with Finance.
- Manage incidents. Be the person who declares one: assess impact, notify users and the team, keep the status page current, coordinate to resolution, then write the post-incident review with a root cause and actions that actually get done.
- Cut the ticket volume at source. Turn recurring escalations into permanent fixes: bug reports Engineering prioritises, product changes, internal diagnostic tooling, and written playbooks that let tier 1 handle the case themselves next time. Success looks like fewer escalations reaching you each quarter, not more.
- Handle deadline peaks. Late January Self Assessment, the 5 April year end and quarterly VAT/MTD deadlines turn every technical fault into an urgent one. Cover, monitoring and rollback plans get agreed before those windows, not during.
- Guard data and access. Verify identity before touching an account, work under UK GDPR with financial and personal data, keep production access to what your role requires, and escalate suspected security or data incidents immediately.

 What we're looking for

- 3+ years in technical support, application support or a tier-2/escalations role for a live software product — ideally consumer-facing.
- You can read a log, write a SQL SELECT, call an API endpoint with Postman / curl and inspect a JSON response without help.
- Practical experience with bug triage alongside an engineering team: severity, reproduction, prioritisation, verification.
- Experience with third-party integrations or API failures, and dealing directly with vendor support.
- Written English clear enough to explain a technical cause to a user in plain terms and to a developer in precise ones.
- Calm and methodical during outages — no panic, no guessing, no silence.
 

Nice to have

- Fintech, accounting, payroll or payments background — bank feeds, Open Banking, reconciliation, double entry.
- Mobile support experience: crash reporting, device fragmentation, store release cycles, RevenueCat or similar subscription tooling.
- Scripting for diagnostics or reporting (Python / SQL / Bash).
- Experience setting up monitoring, alerting or an internal admin/diagnostic tool.
- Any incident-management framework in practice, on-call rotations, blameless post-mortems).

What we offer

- £20 000 plus a bonus.
- A function you own and build, with the tooling budget and production access to do it properly.
- Remote  working with core hours 09:00–18:00 UK. On-call is limited to release windows and tax-deadline peaks, compensated at rate.
- Annual leave plus UK bank holidays, with peak-season cover agreed in advance.
- Direct line to Engineering — your bug reports go into the sprint, not into a backlog nobody reads.
- Tools and training funded, including certifications relevant to the role.

The Mission
Are you a cloud architect who finds beauty in a perfectly orchestrated pipeline? Do you believe that “manual” is a four-letter word? We are looking for a Senior SRE specialized in BI Ecosystems to join our mission-critical Infrastructure team.
In this role, you won’t just “maintain” systems; you will be the master weaver connecting our advanced Data Analytics tools with a rock-solid, automated GCP/AWS backbone. You will bridge the gap between traditional Business Intelligence and modern Cloud Engineering, ensuring our data flows are fast, our visualizations are seamless, and our infrastructure is invisible.

What You Will Do
1. Master the Orchestration (GCP & GKE)
You will take full ownership of our Google Kubernetes Engine (GKE) clusters. This isn’t just
about pods and services; you’ll manage advanced networking (VPC Service Controls, Shared VPC) and high-availability node configurations to ensure our data platforms never skip a beat.
2. Advance Data Architectures (Lakehouse)
You will design and support a unified Data Lakehouse architecture by integrating BigQuery and Cloud Storage. Your mission is to break down silos, ensuring that our raw data and analytical models coexist in a single, high-performance ecosystem. You will implement robust governance and security policies that ensure data quality and accessibility, providing a “single source of truth” that is both scalable and cost-effective
3. Evangelize Infrastructure as Code (IaC)

Tableau, or Similars environments on GCP, handling everything from SSO/IAM authentication to high-performance connectivity with our backend data sources.
5. Hybrid Cloud & Legacy Modernization
Complexity is our playground. You will manage critical AWS resources (EC2, S3) and ensure
seamless interoperability with GCP. Simultaneously, you will lead the charge in migrating legacy monolithic systems into modern, microservices-based architectures.
6. Data Engineering Collaboration
Working side-by-side with Data Engineers, you’ll help build and maintain robust pipelines using Cloud Dataflow, Cloud Composer (Airflow), and BigQuery. You ensure that the “plumbing” of our data world is leak-proof and high-performing.
7. Reliability, Security & FinOps
● CI/CD: Design sophisticated pipelines (GitLab CI/GitHub Actions) integrating DevSecOps best practices.
● Observability: Implement deep monitoring using Google Cloud Operations Suite and Grafana.
● FinOps: Be the guardian of our budget, identifying and eliminating cloud waste through
smart optimization.

Who You Are (Requirements)
