*not applicable for freelancers

• 7+ years engineering, with at least 3 shipping consumer or marketplace products in production.
• Full-stack — comfortable in TypeScript/Node + Python + SQL. Our stack: AWS/EKS, Supabase, n8n, Zoho.
• Has built feature-flag systems, A/B test harnesses, or cohort experimentation infra.
• Has worked alongside AI/ML systems in production (LLM-powered features, scoring models, automation pipelines).
• Comfortable owning a small slice end-to-end (DB → API → UI → analytics).
• Ships fast — can show 5+ production experiments shipped in any 90-day window of your career.
• English C1+; your users are American real estate investors, and communication needs to be sharp and clear.
• AI-first by default — if you are not using AI to 3x your output already, you will be behind the rest of the team.
• High ownership and strong decision-making in ambiguous, fast-moving environments.

• Attend customer interviews alongside the PM and Designer — yes, you, in the call.
• Ship assumption tests in 2–5 days using feature flags and cohort splits, not 2–5 weeks of build.
• Build and maintain the experimentation harness so future tests take days, not weeks.
• Own slices end-to-end — database, API, UI, and analytics instrumentation.
• Scope spikes the same afternoon the designer brings a prototype to the trio.
• Monitor early signal, instrument what's missing, and decide ship-to-100% / iterate / kill with the trio.
• Build new revenue flows end-to-end when the tree calls for it — concierge first, automated second.
• Track competitor releases closely and know what they shipped before users tell you.
  
  

• You treat product as someone else's problem.
• You are an "architecture astronaut" who wants to refactor before shipping.
• You haven't talked to a real user in the last quarter.
• You say "I don't do front-end" or "I don't do back-end."
• Your proudest project is a migration.
  
  

• End of week 1: you have paired with the CTO on the stack, have shipping access to the lead-card UI in production, and understand the end-to-end pipeline.
• End of month 1: you have shipped the first 3 assumption tests with the trio and built the experimentation harness (feature flags + cohort splits + analytics) so the next tests take days, not weeks.
• End of quarter 1 (the bar): 12+ assumption tests shipped, a new revenue-flow track built end-to-end, and the trio's test-design-to-ship cycle reduced to under 5 business days.
• How We Work With You: We use honest checkpoints at 2 weeks, 1 month, and 2 months. We judge trajectory, not perfection. Wrong fast and corrected beats slow and safe. If the fit is wrong, both sides should know by month 2 and say it out loud.

• Experience with n8n, Supabase, or similar low-code automation engines.
• AI integration experience (OpenAI API, Anthropic API, vector databases, RAG systems).
• Marketplace, lead-gen, or real estate domain experience.
• Has worked on lead-scoring or fraud-detection systems.
• Has worked in a trio model before.

• Impact: Work at the core of a product-led, AI-powered startup where your code directly affects business performance.
• Autonomy: High ownership, low bureaucracy, and real authority over what ships.
• Flexibility: Remote-first culture with flexible hours and async-friendly communication. 4+ hour overlap with Asia/Dubai required for weekly trio reviews.
• Compensation: Competitive salary above the market average.
• Team: Join a smart, passionate team that moves fast, supports each other, and builds cool stuff.
• Time Off: Three weeks paid vacation plus 5 paid sick days annually.
• Growth: Unlimited learning policy — paid courses, books, and growth resources.
• AI-Heavy Environment: AI is deeply embedded across prospecting, research, and workflows.
• Ownership: Real decision-making power and direct ownership of your outcomes.
  
  
  
• Location: Remote, 4+ hour overlap with Asia/Dubai

• 5+ years in product design, with at least 2 in a continuous discovery environment.
• Strong end-to-end product designer — UX, UI, interaction, and prototyping. Not visual-only.
• Shipped at least 3 production experiments where YOUR design moved a real business metric.
• Comfortable in Figma + Framer / ProtoPie / code prototypes.
• Has personally run 50+ usability tests.
• Can sketch a prototype LIVE during an interview synthesis session.
• English C1+; your users are American real estate investors, and communication needs to be sharp and clear.
• AI-first by default — if you are not using AI to 3x your output already, you will be behind our engineers.
• High ownership and strong decision-making in ambiguous, fast-moving environments.
• 
  

• Attend every customer interview alongside the PM and Engineer — no exceptions. Take notes on friction in real time.
• Map current end-to-end flows (every screen, every email, every SMS, every refund touch) and identify the highest-friction moments with evidence.
• Design assumption-test prototypes built to disprove or validate the riskiest belief — not to look polished.
• Build multiple prototype directions per test so the trio can pick, not just approve.
• Run usability tests yourself and bring findings back into the next iteration within 48 hours.
• Ship winning treatments to 100% of users and kill losing ones publicly.
• Pair tightly with engineering — no over-the-wall handoffs. You stay in the build until it ships.
• Track competitor experience changes closely and know what they shipped before users tell you.

• Your portfolio is Dribble shots with no shipped outcomes.
• You hand off to engineering and walk away.
• You have never sat in a customer interview.
• You call yourself a "design lead" but have only managed people.
• You are a pixel-pusher who doesn't think in flows.

• End of week 1: you have sat in on the first 5 buyer interviews, mapped the current purchase flow end-to-end, and identified the 5 highest-friction moments with evidence.
• End of month 1: you have designed and shipped the first assumption-test prototype, built 3 alternative directions for the trio to choose between, and run 5 usability tests on the winner.
• End of quarter 1 (the bar): the winning treatment is shipped to 100% of buyers, at least 2 production-shipped flows are informed by tests you designed, and the trio's interview-to-prototype turnaround is established at 48 hours.
• How We Work With You: We use honest checkpoints at 2 weeks, 1 month, and 2 months. We judge trajectory, not perfection. Wrong fast and corrected beats slow and safe. If the fit is wrong, both sides should know by month 2 and say it out loud.

• Marketplace or two-sided platform design experience.
• Background in trust UX (Stripe, Plaid, Shopify, Mercury, escrow, real estate).
• Experience with AI-driven UX (lead scoring, recommendations, chat).
• Real estate or wholesaler customer empathy.
• Visual identity / brand work — premium direct-response aesthetic.

• Impact: Work at the core of a product-led, AI-powered startup where your decisions directly affect business performance.
• Autonomy: High ownership, low bureaucracy, and real authority over product direction.
• Flexibility: Remote-first culture with flexible hours and async-friendly communication. 4+ hour overlap with Asia/Dubai required for weekly trio reviews.
• Compensation: Competitive salary above the market average.
• Team: Join a smart, passionate team that moves fast, supports each other, and builds cool stuff.
• Time Off: Three weeks paid vacation plus 5 paid sick days annually.
• Growth: Unlimited learning policy — paid courses, books, and growth resources.
• AI-Heavy Environment: AI is deeply embedded across prospecting, research, and workflows.
• Ownership: Real decision-making power and direct ownership of your outcomes.

• Location: Remote, 4+ hour overlap with Asia/Dubai

We are looking for a Senior 2D Designer who will create in-game visual elements for slot games: logos, pop-ups, symbols, frames, UI elements and other in-game graphics.

The role works within an established visual style and art direction.

• Good communication and teamwork skills.

  
  Responsibilities:

• Create and adapt in-game visual assets for slot games: logos, symbols, UI panels, pop-ups, counters, frames, buttons and win indicators;
• Improve and refine existing in-game content (polishing, reskins, adaptations);
• Prepare and optimize graphic assets for developers and animators (layers, formats, export, naming);
• Adapt visuals to different themes and styles (seasonal versions, variations, reskins);
• Create supporting promotional materials related to the games (banners, simple promo visuals, marketing assets when required);
• Collaborate closely with Artists, Game Designers and Developers to ensure high-quality in-game implementation;
• Maintain visual consistency and quality across all game features and interfaces;

• Work with tasks and feedback using Jira and Miro.

  
  We offer:

• A competitive rate fixed in EUR with an annual review;
