Full Stack Developer (Backend + Frontend skills required)
Full-Stack Developer (React + Node.js — Web SaaS)
What we're building
We're a small studio shipping several products across web and mobile: an AI-powered platform for creators, a sponsorship-intelligence platform, a live subscription app on iOS and Android, and more in the pipeline. You'll work across this portfolio — full-stack — taking over and extending existing production code rather than building from scratch.
About the role
Your immediate focus is integration work on one of our creator platforms: the frontend and backend are built — we need the integrations wired up (payments, AI/LLM flows, third-party APIs). Over time you'll contribute across the other products as they evolve.
This is a hands-on full-stack web role: we need someone with real production experience building SaaS web applications on both the frontend (React) and the backend (Node.js, Supabase, REST APIs, third-party integrations) — not a specialist in one.
We're looking for someone earlier in their career but genuinely capable: past the "still learning to ship" stage, hungry to prove themselves, and reliable.
What you'll do
- Complete integrations on top of an existing frontend/backend — e.g. Stripe Connect payouts, the AI/LLM content-processing flow, and related REST APIs.
- Build and extend features across our SaaS platforms: React frontends, Node.js / Supabase backends, server-side logic, and internal tools.
- Fix UI/responsiveness issues and ship reliable updates to production.
- If you also have React Native / Expo experience, contribute to our mobile app (language expansion, UI fixes, store releases) — a plus, not a requirement.
Must have
- 2+ years hands-on experience building production web apps / SaaS products, full-stack.
- Frontend: strong React (TypeScript) — components, state management, responsive layouts, and working comfortably in an existing codebase.
- Backend: Node.js server-side logic, building and consuming REST APIs, and working with Supabase (Postgres) or Firebase — auth, data models, webhooks, and wiring up third-party services.
- Strong JavaScript / TypeScript across the stack.
- Comfortable with third-party API and payment integration (Stripe). Stripe Connect is a strong plus.
- Tests own work thoroughly before shipping; reliable, detail-oriented; communicates clearly in English and flags blockers early.
Nice to have
- React Native + Expo experience, ideally with an app shipped to the App Store and/or Play Store (App Store Connect / TestFlight, Google Play releases; a Mac plus iPhone/Android for testing).
- App localization / i18n experience, including RTL languages (Hebrew).
- AI/LLM API integration, transcription/vision pipelines.
- Push notifications (FCM/APNs), RevenueCat or in-app subscriptions, CI/CD.
How we work
- Clear written requirements and acceptance criteria before you start.
- "Done" means tested end-to-end with proof (a short recording or screenshots) — not just "works on my machine."
- Only build what's agreed; propose before adding or changing scope. Never delete production/client data without sign-off.
- Short daily update: what's done (with proof), what's next, and any blockers.
Logistics
Fully remote, open to developers in India. You'll work across several products, so variety and range matter. We pay fairly for solid mid-level work, with real room to grow in scope and pay as the portfolio expands.
