About Solo60: A London-based fitness scale-up whose platform manages dynamic bookings, PT matching, and studio analytics.
Stack: React Native (Expo), Next.js, Supabase, Vercel/AWS, Stripe, GitHub Actions, Hex, Figma — with a growing IoT footprint across studios.
The Role: You'll be the second Full Stack engineer, reporting to the Tech Lead. Wide surface area, real ownership, and a direct line into product and commercial decisions. This is a 2026 Product Engineer role. You own the loop from Figma to production, including QA, releases, observability, and postmortems. AI tooling (Claude Code is part of the daily workflow) makes that surface area manageable. It doesn't lower the bar. For the right person, this is a genuine career accelerator — with a clear path to a Lead Engineer position as the team grows.
What You'll Do:
- Build across Next.js, Supabase, and React Native — features end-to-end from design to production
- Own mobile releases on App Store and Google Play (versioning, staged rollouts, rejection handling)
- Integrate and maintain Stripe: subscriptions, webhooks, reconciliation, edge cases
- Contribute to the analytics pipeline and Hex dashboards
- Own and improve CI/CD pipelines (GitHub Actions, static analysis, type checking, tests)
- Level up testing discipline: unit, integration, E2E (Playwright / Maestro)
- Use AI tooling as a force multiplier — build workflows, review output critically, raise the team's bar
- Write documentation that survives you: ADRs, runbooks, READMEs
- Take your turn on production issues and write honest postmortems
What We're Looking For:
- Core experience: 5+ years full-stack with production Node.js, Next.js, and React Native
- Supabase fluency, or deep enough Postgres (RLS, functions, realtime) to get there fast
- Shipped mobile apps to both stores — including review rejections and staged rollouts
- Real production Stripe: webhooks, idempotency, retries, reconciliation
- Vercel experience: preview deployments, edge functions, environment management
- Figma-to-code fluency with design system judgement
- Designed and owned CI/CD pipelines with quality gates (SonarQube, CodeQL, or similar)
How you work:
- Daily Claude Code usage — you can talk about what works, what doesn't, where it breaks
- Clear view of what good code looks like; hold the line under pressure
- Test your own work before handoff; own it when something slips through
- Write things down so the next person doesn't have to ask
Nice to have:
- IoT integrations (smart locks)
- Fitness, hospitality, or bookings background
- Webflow Terms
