Build and ship Flutter applications for iOS and Android, including feature development, app store releases, debugging, backend integration, authentication, analytics instrumentation, and native Swift or Kotlin code when needed. The role requires independently shipped app experience, daily use of AI coding tools, clear English communication, strong product judgment, and proactive problem-solving.
This is a remote position.
Synthlane Technologies · Remote (India), occasional visits to our Gurugram office · Full-time
We're hiring one Flutter developer to build and ship our own apps on iOS and Android, end to end. Years of experience don't matter. Shipped work does.
About us
Synthlane is a small product team in Gurugram. Our founder is a staff-level engineer who owns product decisions and reviews your work closely. We build our own products, not client work, on one shared stack: Flutter, FastAPI, Supabase and PostHog. You work directly with the founder, with no layers in between.
What you'll do
- Build features in our Flutter app and ship them to both the Play Store and the App Store, including signing, releases and store review.
- Turn product specs into working screens, and tell us when a spec is wrong or misses edge cases: empty states, offline, slow networks, cheap Android phones.
- Debug your own problems: read the error, form a hypothesis, use AI tools to move faster, then verify the fix.
- Integrate with our FastAPI backend and Supabase auth, and add PostHog events so we know whether a feature worked.
- Write native Swift or Kotlin when a Flutter plugin isn't enough.
You're a fit if
- You have at least one app live on the Play Store or App Store that you built mostly yourself. A personal project counts.
- You use AI coding tools daily (Claude, Cursor, Copilot or similar) and can explain every line you commit.
- You ask "why are we building this?" before you start, and "did it work?" after you ship.
- You write clearly in English over chat. Remote work depends on it.
- You flag problems early instead of explaining missed deadlines later.
You're not a fit if
- You've only built apps from tutorials or courses.
- You paste errors into an AI until something compiles and can't explain why the fix works.
- You need every screen fully specced before you can start.
Nice to have
Riverpod or Bloc in production, platform channels, push notifications, deep links, analytics instrumentation, and access to a Mac for iOS builds.
How we hire
- A short screening form, about 15 minutes. Generic or copy-pasted AI answers are rejected.
- 2 Rounds of Technical Interview
- 1 Round of Product Engineering with Founder
- An offer within a week of the call.
