Jobs at Djinni

We are hiring on behalf of our client – an American media company with an office in Warsaw. They run a high-volume, performance-driven newsletter portfolio and drive traffic to advertisers and brand partners through owned channels. Affiliate revenue is a core part of the business, and they need someone to own the partner relationships that make it work.

This is a senior, commercial role. You will be the main point of contact for advertisers, affiliate networks, and affiliate managers — building relationships strong enough that partners bring you their best deals first, before anyone else sees them.

You will own payout negotiation end to end: commission rates, CPAs, rev shares, bonuses. That means reading performance data, spotting where a deal is underpriced, and pushing for better terms – not just accepting what a partner offers. You also own tracking hygiene across campaigns: links, sub-IDs, attribution, making sure nothing breaks and no revenue leaks.

Responsibilities

1. Partner communication & coordination

• Be the main point of contact for advertisers, affiliate networks, and affiliate managers
• Keep promo schedules, offer updates, performance feedback, and follow-ups tight and proactive
• Build strong relationships so partners prioritize us and share better deals first
• Spot new opportunities early and move fast to secure them

2. Payout negotiation & deal management

• Negotiate commission rates, CPAs, rev shares, and bonuses to maximize earnings
• Regularly review terms and push for improvements based on performance data
• Identify underperforming/undervalued deals and renegotiate with clear numbers
• Manage renewals and escalate when terms need to change

3. Tracking, links & execution

• Own tracking links, sub-IDs, parameters, and attribution hygiene across campaigns
• Prepare promo packages for internal teams (links, copy, creatives, instructions)
• Coordinate launches across multiple partners and deadlines at the same time
• Keep clean records of partners, offers, assets, and timelines

4. Performance & growth

• Monitor partner performance and flag where we’re leaving money on the table
• Improve partner workflows so we execute faster and capture more revenue
• Longer-term: industry events and conferences can be part of growth, but near-term focus is performance and revenue impact

Requirements

• 4+ years in affiliate / performance marketing (preferably publisher/traffic side)
• Proven experience negotiating payouts (CPA, rev share, commissions, bonuses) with advertisers or networks
• Strong understanding of tracking (links, sub-IDs, attribution, what breaks conversions)
• Highly organized with a “zero mistakes” mindset
• Strong English (C1+)
• Comfortable managing multiple partners and deadlines in parallel
• Hungry to grow, performance-oriented, and comfortable with occasional irregular hours when needed

Nice to have

• Experience with Impact, CJ, ShareASale (or similar platforms)
• Affiliate network relationships / strong partner Rolodex
• Experience in digital media / newsletter monetization
• Comfortable attending industry events

What we offer

• Competitive salary + performance-based bonuses
• 21 paid vacation days + 14 paid sick leaves
• Warsaw office available (hybrid setup)
• A fast-moving, high-performing team with real ownership and growth opportunities

🎯 Mission of the Role

The primary mission of this role is to design highly effective user experiences, logic, and interfaces for high‑conversion funnels. All design decisions must be grounded in quantitative and qualitative research of user behavior and sentiment, aimed at reducing cognitive load, removing barriers in the user journey, and driving systematic conversion growth.

🧠 Required Skills

• Proven ability to formulate and defend professional UX/UI decisions based on quantitative and qualitative user data, not subjective preferences.
• At least 2 years of experience as a UI/UX Designer.
• Demonstrable UI design skills with a strong portfolio.
• Strong knowledge of typography, color theory, composition, and modern UI trends.
• Experience working with eCommerce project.
• Familiarity with design requirements for SaaS products and mobile apps (preferred).

🌟 Nice to Have

• Experience conducting qualitative UX research to identify conversion growth opportunities and optimal IX/UI solutions.
• Background in data‑driven teams, working closely with analysts to obtain necessary data to create strong UX/UI solutions for improving funnel performance.
•  

🚀 What We Offer

• Direct Impact on Millions: your work will directly improve the experience of around 50M monthly users across multiple clients. We partner with successful and ethical businesses, including eCommerce stores, SaaS products, mobile/web applications, and lead generation funnels.
• Ownership and Freedom: you make UI decisions independently, validated through A/B testing, without relying on client “taste” or subjective opinions.
• 100% Data‑Driven Culture: every hypothesis is tested and validated with statistically significant data. We combine insights and best practices with data to deliver the highest‑quality design outcomes.
•  

📊 Responsibilities

• Identify UX friction points and conversion opportunities using user research and analytics.
• Design user interfaces and user flows that improve conversion and other key business metrics.
• Create UI variations for A/B tests and optimization experiments based on validated hypotheses.

Position Overview

NYC Glass & Window Repair is looking for a motivated, organized, and results-driven Sales Representative to manage incoming leads, communicate with residential and commercial customers, prepare estimates, follow up on opportunities, and convert inquiries into booked projects.

The ideal candidate is comfortable speaking with customers, understands consultative sales, follows up consistently, and takes ownership of every lead from the initial inquiry through closing and handoff to the operations team.

Experience in windows, doors, glass, construction, home improvement, or building services is highly preferred but not required if the candidate is willing and able to learn the technical aspects of our services.

Key Responsibilities

• Respond quickly to new leads received by phone, email, website, text, and other channels.
• Speak with customers to understand the problem, project scope, budget, timeline, and expectations.
• Review customer photos, videos, measurements, drawings, and project documentation.
• Determine whether the project can be quoted remotely or requires an on-site assessment.
• Schedule site visits and coordinate with estimators when necessary.
• Prepare and send professional estimates and proposals.
• Explain proposed solutions, materials, hardware, glass options, lead times, warranties, and pricing to customers.
• Follow up consistently on all open estimates and sales opportunities.
• Negotiate professionally while protecting company margins.
• Convert qualified leads into signed/approved projects and collect required deposits.
• Upsell and cross-sell appropriate services when they genuinely benefit the customer.
• Maintain accurate customer information, notes, estimates, follow-up dates, and sales stages in the CRM system.
• Re-engage previous customers and older leads when appropriate.
• Coordinate sold projects with scheduling, purchasing, project management, and installation teams.
• Maintain communication with customers until the project has been properly handed off.
• Develop long-term relationships with property managers, general contractors, architects, designers, building owners, and repeat customers.
• Meet individual sales, revenue, conversion-rate, and follow-up KPIs.

Services the Sales Representative Will Sell

The representative will be trained to sell services including window repair and replacement, insulated glass (IGU) replacement, commercial and residential glass replacement, door repair and installation, storefront glass and aluminum systems, shower enclosures, custom mirrors, glass partitions, railings, historical window restoration, window screens, smart glass and window film, and specialty glazing projects.

Sales Process

The Sales Representative is expected to take ownership of the sales pipeline:

New Lead → Qualification → Site Visit/Estimate → Proposal → Follow-Up → Negotiation → Closing → Deposit → Operations Handoff

A lead should never be left without a clearly documented next action or follow-up date.

Requirements

The ideal candidate should have excellent verbal and written English, strong communication and negotiation skills, and the confidence to speak with both homeowners and commercial clients.

The candidate must be highly organized, comfortable working with CRM systems, able to manage multiple opportunities simultaneously, and persistent with follow-ups without being overly aggressive.

Basic mathematical skills are required for measurements, quantities, pricing, percentages, and margins. The candidate must also be comfortable learning technical terminology related to glass, windows, doors, hardware, framing systems, and construction.

Preferred Experience

Previous experience in construction sales, window and door sales, glass and glazing, home improvement, building materials, property services, or B2B sales is a strong advantage.

Experience dealing with property managers, general contractors, architects, designers, management companies, and commercial clients is also highly desirable.

Key Performance Indicators (KPIs)

Performance should be evaluated primarily on sales revenue, gross profit/margin, lead-to-sale conversion rate, estimate-to-sale conversion rate, speed of response to new leads, follow-up completion rate, average project value, CRM accuracy, and repeat/referral business.

What We Are Looking For

We want someone who is sales-driven but not pushy. The goal is not simply to give customers a price—it is to understand what they need, recommend the correct solution, explain why it is the right solution, build trust, and close the project.

The right candidate should think:

“Every qualified lead needs a clear next step until the customer buys, declines, or the opportunity is formally closed.”

NYC Glass & Window Repair is looking for a creative, energetic, and highly organized Content Creator to develop engaging social media content showcasing our projects, team, services, and day-to-day operations.

The ideal candidate understands how to turn real construction and service projects into compelling Instagram Reels, TikTok videos, YouTube Shorts, Facebook content, and other short-form videos that generate attention, engagement, brand awareness, and ultimately new customers.

This position requires more than simply recording videos. We are looking for someone who understands storytelling, hooks, trends, editing, captions, and social media algorithms and can consistently identify opportunities for interesting content.

Key Responsibilities

• Visit job sites and create photo and video content of ongoing and completed projects.
• Film before-and-after transformations, installations, repairs, technician processes, and finished results.
• Create and edit short-form videos for Instagram Reels, TikTok, YouTube Shorts, Facebook, and other platforms.
• Develop strong hooks and concepts designed to capture attention within the first few seconds.
• Turn technical projects such as window repair, glass replacement, storefront installation, shower enclosures, glass partitions, and door installations into content that is easy and interesting for customers to understand.
• Interview technicians, project managers, customers, and other team members when appropriate.
• Create educational content answering common customer questions.
• Write engaging captions, titles, descriptions, and calls to action.
• Follow current social media trends and adapt relevant formats to the company.
• Maintain a consistent posting and content-production schedule.
• Organize raw footage, completed videos, photographs, and other digital assets.
• Coordinate with the office, sales team, and technicians to identify upcoming projects worth filming.
• Repurpose one project into multiple pieces of content for different platforms.
• Monitor content performance and identify which topics, hooks, formats, and videos generate the strongest engagement and leads.
• Develop new creative ideas instead of waiting for detailed instructions for every video.
• Maintain professional brand standards across all published content.

Content We Want to Produce

The creator should be comfortable developing content such as before-and-after videos, emergency glass repairs, broken-to-restored transformations, luxury shower enclosures, storefront installations, historical window restoration, large custom glass projects, educational “Did you know?” videos, common window problems, behind-the-scenes footage, technician POV videos, customer testimonials, project walkthroughs, and visually satisfying installation videos.

Requirements

The ideal candidate should have proven experience creating social media content and strong skills in video shooting and editing. Experience with CapCut, Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve, or similar software is preferred. The candidate should understand Instagram, TikTok, YouTube Shorts, and current short-form content trends and be able to create professional content using both smartphones and cameras.

Strong English communication, attention to detail, reliability, creativity, and the ability to work independently are important. Experience creating content for construction, home improvement, architecture, real estate, interior design, or service businesses is a major advantage.

What Success Looks Like

Success in this position will be measured by consistent production of high-quality content, growth in organic reach and engagement, increased views and followers, development of recognizable company branding, and—most importantly—social media inquiries and leads that convert into customers.

Preferred Candidate

We are looking for someone who sees a completed glass installation and immediately thinks:

“How can I turn this into a video people will want to watch?”

The right person should be creative, proactive, comfortable visiting active job sites, and capable of taking ownership of the content-production process from idea → filming → editing → publishing → performance analysis.

At Noomo Agency, we're seeking a Senior UI/UX Designer (full-time or part-time) with excellent visual skills and extensive experience in website design.

Position: Part-time or Full-time (both options are welcome)

Experience Required: Minimum 10 years

What matters to us:
→ Strong visual design — you care about every detail, from typography to composition
→ Experience with 3D websites and interactive web experiences
→ Clear communication — you can present your thinking and bring others along
→ Remote, self-directed, and collaborative by nature

Must-Have

• Strong typography and composition skills
• Experience working with a large enterprise
• Strong communication skills
• Being a team player
• Thinking outside the box

ElevateOS integrates with 20+ smart-device ecosystems — keyless entry, locks, cameras, switches, thermostats. Every integration is validated against physical hardware before release. We're hiring the person who owns that entire pipeline: the device lab itself, the test environments and servers behind it, and the integration testing that runs on top.

Who we need: someone technical who can host and run a physical device lab from their home in Kraków — smart locks, cameras, access-control hardware — and also handle the server/networking side so our developers can remotely connect to and test against that hardware.

You'll build and run your own hardware lab — smart locks, cameras, access control systems, and the servers and test environments behind them. Every device integration we ship passes through your hands before it reaches production, and you'll work directly with the development team and CTO with real autonomy: you decide how the lab, its environments, and its tooling evolve. The role spans mobile, backend, networking, and physical hardware — a breadth almost no single position offers. If you're the type who runs a home lab for fun, this is that, with a company budget behind it.

About ElevateOS

ElevateOS has been improving the resident experience for over seven years. We built a single, all-in-one platform that lets property managers and resident staff work together, replacing multiple confusing apps with one intuitive solution. The product is stable, growing, and US-based. Our stack is JavaScript end to end: React, Node.js, and React Native.

What you'll own:

- The physical device lab — smart locks, access-control hardware, cameras, switches — hosted at your home in Kraków. Setup, configuration, firmware updates, troubleshooting, and inventory.

- Test environments and servers — install, configure, and maintain the local and staging environments our integrations run against; adjust configurations live during debugging sessions with developers.

- Lab networking — device connectivity (Wi-Fi, BLE, Zigbee/Z-Wave), router and network configuration, and remote access so the dev team can reach devices and environments from anywhere.

- Integration testing — install iOS/Android builds, run end-to-end tests against physical devices, API testing, reproduce and isolate bugs, verify fixes with the team.

- Documentation — device matrix, environment runbooks, test protocols, and findings.

Requirements:

- Based in or near Kraków — the hardware lives with you; the work is otherwise remote.

- Solid Linux and networking fundamentals: comfortable in a terminal with SSH and logs, and with DNS/DHCP/port-level debugging.

- Experience setting up and maintaining servers or local test environments (Node.js ecosystem and Docker familiarity as a plus).

- Hands-on comfort with hardware, physical devices and space at home to host the lab.

- Able to read code (JavaScript/TypeScript), work with APIs (curl, Postman), and read mobile logs.

- Commercial experience (2+y) in a technical role — engineering, QA, sysadmin/devops, technical support.

- Strong troubleshooting instincts and good English communication.

Nice to have:

Exposure to React Native, Kotlin, or Swift; mobile SDK integrations.

Familiarity with smart locks, access control, or keyless entry ecosystems.

MQTT, webhooks, RTSP/video streaming.

Test automation experience; CI/CD (GitHub Actions).

Practical details:

Company hardware is currently distributed across two locations in Kraków and will be consolidated with you during onboarding.

Occasional in-person device handoffs in Kraków.

SignalsAPI monitors 290+ sources to detect hiring signals — job postings, funding rounds, company news — and turns them into warm leads for recruitment and staffing agencies. Our customers are agency owners and founders, mostly UK and US.

We're hiring someone to make SignalsAPI a familiar name inside that world on LinkedIn.

The role in one sentence

Spend time every day where recruitment agency owners spend theirs, and become a face they recognise — before anyone ever tries to sell them anything.

What you'll actually do

• Map the recruitment-agency world on LinkedIn: who the influential voices are, which posts the niche actually reads, where the arguments happen.
• Comment on those posts. Daily. With something worth reading — a real reaction, a question, a counterpoint. Not "Great post!"
• Connect with agency owners, staffing founders, and the people around them.
• Notice what's landing — which comments get replies, which topics pull people in — and tell us weekly.

What this job is not

We want to be very clear, because this attracts the wrong applicants otherwise:

• No pitching. You will never send a sales message.
• No sequences, no campaigns, no Expandi / Apollo / Lemlist. Nothing automated.
• No meeting quota. Nobody is counting your booked calls, because you won't be booking any.

If your strength is sending 500 messages a week, this will make you miserable and you'll be bad at it. That's a different job at a different company.

You're a fit if

• Your written English is genuinely fluent. Everything you write here is public, permanent, and read by the people we sell to. This is the hard requirement.
• You've run LinkedIn for a B2B company, or built a following of your own on it.
• You have taste. You can read a post and tell the difference between a real insight and a platitude — and you can say why.
• You're comfortable spending your first month learning an industry you don't know yet.

Bonus, not required

• You've worked in recruiting or staffing — agency-side especially. You'd already speak the language.
• Community management background: Discord, Slack, forums, anywhere people actually talk.
• You post on LinkedIn yourself and have opinions about what works there.

Probably not a fit if

• Your experience is mostly Instagram/TikTok, reels and visual brand content. Different craft, and we'd both find out the hard way.
• You've worked in engagement pods or comment automation. The whole point is that this is real.

Practicalities

• Fully remote, part-time — around 4 hours a day, but every day. Consistency matters far more than hours here.
• Some overlap with UK working hours, since that's when the feed is alive.
• Long-term. This role takes 6–8 weeks to start showing results and we know that.

About your cover letter

Please don't summarise your CV — we've read it. Tell us instead about one industry, scene or community you came into from the outside, and how you got to the point where people there took you seriously. That's the actual job, so it's the thing we most want to hear about.

We're a small, senior team that ships. You'll have real ownership from day one.

The role

We're hiring a Senior Full-Stack Developer to help take our web games to the next level — building new gameplay, tightening performance, and growing the services behind accounts, scores, and matchmaking.

You'll work across the whole stack: the React front end, the HTML5 canvas game engine, and the Node/Express + SQLite backend that powers it all.

What you'll do

- Design and build new game features and polished, responsive UI in React + TailwindCSS.

- Write and optimize HTML5 Canvas game logic — physics, input, rendering, and a smooth 60 fps loop.

- Build and maintain backend services: REST APIs, authentication, persistence, leaderboards.

- Profile and fix performance bottlenecks across load time and interaction (large lists, render cost, network waterfalls).

- Own features end-to-end — from spec, through implementation and testing, to release.

- Raise the bar on code quality through reviews, sensible architecture, and pragmatic tests.

You don't need every item, but you should be strong in most of it:

- Front end: React 18 (hooks, context), Vite, TailwindCSS, modern JavaScript (ES2022+)

- Game/graphics: HTML5 Canvas 2D, `requestAnimationFrame` game loops, basic 2D physics

- Back end: Node.js, Express, REST API design

- Data & auth: SQLite (or similar), password hashing/sessions, secure auth flows

- Tooling: Git, npm, browser dev tools / profiling

What we're looking for

- 5+ years building production web applications, with real front-end depth.

- Fluency in React and modern JavaScript; you understand rendering, state, and re-render cost.

- Experience building and consuming HTTP APIs and working with a relational store.

- A track record of diagnosing performance problems with data, not guesswork.

- Care for UX and visual polish — you notice jank and fix it.

- Clear written communication and the self-direction to own work in a small team.

Nice to have

- Shipped a game or interactive/animation-heavy app on the web.

- Canvas/WebGL, audio, or real-time (WebSocket) experience.

- Security mindset for auth, sessions, and input validation.

- TypeScript.

What we offer

- [Competitive salary + equity/bonus]

- [Remote-first / flexible hours]

- [Health, learning budget, hardware, PTO — fill in]

- Small team, high ownership, real players using what you ship.

Take-home assignment

Strong candidates are invited to a paid / time-boxed take-home (~[3–4] hours)

built on a slimmed-down version of our real Moto Stunt Riders codebase

(React + Vite + Tailwind on the front end; Node/Express + SQLite on the back end).

You'll receive the repository with a short TASK.md. Typical assignments include:

1. Performance — The garage screen renders thousands of bikes and the search / sort / favorite interactions lag. Find *why* (measure, don't guess) and make it smooth without changing behavior.

2. Feature — Add a self-contained feature end-to-end (e.g. a new gameplay  mechanic, an API endpoint + UI, or an auth improvement) that fits the existing  architecture.

We evaluate:

- Correctness & UX — does it work, and does it feel good to use?

- Problem-solving — for perf tasks, did you *measure* the real bottleneck?

- Code quality — clear, consistent with the codebase, appropriately tested.

- Communication — a short write-up of your approach, trade-offs, and what you'd

  do next with more time. A before/after measurement (numbers or a short clip) is a plus.

Please keep changes scoped to the task, and don't rewrite unrelated code.

About the role

Rogue Studio is the highest-quality uncensored AI image and video generation studio — built for AI artists and adult creators alike. We're looking for a Creative Content Producer to own the visual storytelling that brings our brand and product to life across YouTube and social.

You'll turn our mission and new features into content people actually want to watch and share — pitching concepts, getting them approved, and executing them at a high bar. If you can make a feature launch feel like an event and a brand feel like a movement, this is your lane.

Note: Rogue Studio operates in the adult (18+) space. This role involves creating and working with adult content. Comfort with mature, uncensored material is required.

What you'll do

1. Brand & feature storytelling. Take our mission, themes, and new features and build narratives that showcase our brand identity and sell users on what's new. Pitch concepts for approval, then execute to notes for use across YouTube and social. (Style reference: youtube.com/watch?v=RzNDm4sA80Y)
2. Social concepts & carousels. Develop concepts and social-media carousels from briefs set by the CMO. Batch-create and schedule posts for publishing on approval. (Style reference: instagram.com/outlandermagazine)
3. Motion graphics. Produce motion-graphic videos that showcase new features — in-app banners, tutorials, and promos.

4. AI art. Create on-brand AI art that meets our briefs and quality expectations.

    

What we're looking for

• A strong portfolio/reel of brand and social content — storytelling first, not just pretty visuals.
• Motion graphics skills (After Effects or equivalent) for short-form video, banners, and tutorials.
• Proficiency with AI art/generation tools and a sharp eye for quality and brand consistency.
• Fluency in social formats — YouTube, Instagram/TikTok carousels and short video — and what performs on each.
• Ability to take a brief from concept to approved, scheduled, published content — and to iterate quickly on notes.
• Comfortable creating adult (18+) content.

Nice to have

• Experience marketing AI, creator-economy, or adult-industry products.
• Copywriting chops to pair with the visuals.
• Familiarity with social scheduling tools and batch production workflows
