• 3+ years in product design, with at least 2 (ideally 3) in consumer mobile apps. B2B-only backgrounds won't be a fit.
• Strong, modern mobile UX and UI craft. The Head of Product looks closely at portfolios, so yours should show it.
• Ownership: when a problem lands on your desk, you carry it through without waiting to be told the next step.
• Product thinking: you care about product metrics and experiments, not only the interface.
• Experience running user interviews. Usability testing and research methods can be learned on the job.
• English at B2–C1 and Russian.
• Clear, structured communication, including when you're thinking out loud with the team.
• You enjoy a high pace and take direct feedback well.
• You want to build good things for users, not just hit numbers at any cost.
• Nice to have: an app or side project you launched yourself, and builder or no-code skills.
• A direct partnership with a strong PM, and a Head of Product who cares about design.
• Real ownership, access to analytics and A/B data, and room to build things yourself.
• Remote work, offices in Warsaw and Cyprus, and an offsite about once a year.
• 21 calendar days of paid vacation plus 10 public holidays of your country, and 7 paid sick days.
• €50/month towards health insurance after probation, and a MacBook Air (13" or 15").
• €4,500–5,500/month gross on a B2B contract with StellarTech's Cyprus entity, paid in USD. You'll need your own sole proprietorship. Probation is 3 months.
