About StellarTech

StellarTech 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.
