Tech Stack: React Native, Expo, Swift & Kotlin, Node.js/Express, Postgres, AWS...

About you

You’re an expert software engineer with outstanding attention to UI/UX. When you need to ship backend features, you don’t need someone else to step in. We don’t expect a backend ninja, but simple CRUD shouldn’t intimidate you.

The definition of "expert" varies, so let’s narrow ours down:

• Elite communication: You set expectations accurately and you live up to them. No surprises. Our team works in Russian & English*
• Deep resilience: Bugs, crises, or tough discussions - you have a massive buffer before stress impacts your output. You don't crack under pressure.
• No ego: We are here to win, not to manage insecurities.
• Product mastery: You understand the engineering principles behind the greatest software products ever made. Be ready to discuss under the hood of your tools.

Engineering culture

• Optional code reviews: We trust you. Merge when you're ready. If you want a second pair of eyes, just ask.
• Radical autonomy: We don’t second-guess your decisions. You own the call.
• High-bandwidth collaboration: We talk constantly, so everyone has context without needing formal gates to catch up.
• Direct feedback: When we do review code, comments are blunt, concise, and respectful.
• Ruthless efficiency: We aggressively adopt any tool (AI included) that increases leverage and speed.
• Limited test coverage on FE: We supplement that with good architecture and top talent.
   

About the role

• This is the second seat on our mobile team. Today, one engineer owns our entire mobile codebase end-to-end: live on iOS & Android, paying customers, real subscription revenue.
• You'll partner closely with our founder, our PM, our backend engineer, and our designer. 
• AI is woven through the product itself, not just our build process: features that take real action on the user's behalf, conversational interfaces, LLM-driven recommendations. That means staying close to the models, prototyping fast, and being comfortable shipping into surfaces where the underlying capability is still moving.
• We care deeply about craft, the details that make the product feel polished and trustworthy on a 60fps thread. But we ship fast and learn in the open. We'd rather get a paywall variant in front of users this week than perfect it for a month.
• This role is fully remote with morning Chicago overlap (10am–2pm CT) for standups and demos.

Benefits

1. You’ll learn a lot: Steep learning happens outside of your comfort zone. If you’re eager to learn, it means you’re hungry for uncertainty and discomfort. We only hire people like that. We promise to push you out of your comfort zone and give you access to extract as much knowledge as possible from the environment we’ve created.
2. You’ll get rich: A startup environment often feels like eating glass. And if someone decides to eat glass with us, they deserve their slice of the pie. That’s why besides equity, we also have profit share for core team members as part of our compensation package.
3. Earning your first $1M means enduring $1M worth of pain, but if you’re up for it, we’re here for you. We don’t hire people that aren’t obsessive, so the main question shifts from if to when .
4. You’ll own your slice of the pie: You’ve probably heard stories from corporates about "extreme ownership" that turned out to be capped by a manager. We don’t have managers, you are the one responsible. You’ll have the entire team’s trust.
5. The only limit is business reality: we want to earn money, not just be around.
6. You’ll have our back: Our recruitment philosophy is similar to the Navy Seal’s one. We have a culture where entrepreneurs can thrive. We know exactly what “tough” really means, so we watch each other's backs.

It should feel like a steal

You’ll join a team of experienced builders to create the next massive success. In your first six months, you’ll learn more - while getting paid - than you have in the last few years combined. You will be trusted, respected, and heard. If it doesn’t feel like a steal for you, it’s probably not be what you’re looking for at the moment.
