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.

*Rapidum is an equal opportunities employer. We assess every application against the requirements above and nothing else.*
 

Location: Remote (UK-based) 
 

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.

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)
Our goal is 100% immutability. You will use Terraform to automate the entire lifecycle of our
GCP resources—from Compute Engine and Cloud Run to Cloud SQL—ensuring consistency
across Dev, Staging, and Production.
4. Empower DataViz Excellence
You will be the enabler for our Data Analysts. You’ll deploy, optimize, and scale Qlik Sense,
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)
● Cloud Expert: Proven experience managing complex environments in Google Cloud Platform (GCP) and AWS.
● Data Architect: Deep understanding of Data Lakehouse models and governance.
● Kubernetes Pro: Deep knowledge of GKE, including advanced networking and security policies.
● Terraform Ninja: Ability to write modular, scalable, and secure IaC.
● BI Infrastructure Savvy: Experience deploying and tuning enterprise visualization tools (Tableau, Qlik, or Power BI).
● Automation Mindset: Strong scripting skills (Python, Bash, or Go) and mastery of CI/CD engines.
● Data-Driven: Familiarity with Big Data tools like Airflow, BigQuery, and Dataflow.
● Security-First: Solid understanding of encryption, IAM roles, and network security standards.

Why Join Us?
● Impact: You are not a cog in the machine; you are building the machine.
● Tech Stack: Work with the latest tools in the Cloud and Data world (Lakehouse, GKE).
● Culture: We value technical excellence, proactive problem-solving, and a “fail fast, learn
faster” mentality.
● Growth: We invest in your certifications and continuous learning. Ready to redefine how BI meets SRE? If you are a builder who loves solving the puzzle of high-scale data infrastructure, we want to meet you.

Apply now and let’s build the future of data infrastructure together!
