Job Type: Full-time, B2B contractCompensation: €4,500–5,500/month gross, paid in USDAbout StellarTechStellarTech is a self-funded multi-app company that launches consumer mobile products in different domains.
It is profitable, moves at startup pace and is aiming for $1B in revenue.
You would join Smartimi, the company's biggest and most mature app, as the design partner of its PM, Darya.
Around you: a content team that builds templates, a product analyst, engineers and QA.
The Head of Product has a UX background himself.
The team speaks Russian; the users speak English.
What you are expected to do:Take raw problems, ideas and initiatives and turn them into flows, prototypes and shipped UI for a consumer mobile app.
Work as a pair with the PM, and own some initiatives fully, from idea to release to reading the numbers.
Work directly with engineers and review the build before it ships.
Run A/B tests, read the results in Amplitude and plan the next iteration.
Talk to users: run interviews in English and launch quick surveys.
Build features yourself with vibe-coding or no-code tools when that's faster.
The team has a way to test and ship them.
Marketing banners and funnels are handled by a separate team, so they are not part of this role.
What you need to succeed: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.
