Full-Stack Developer — React/TypeScript + Supabase (RLS, Edge Functions), Clerk, Stripe— Long-Term

We are a biomedical research platform — an AI-powered search engine over ~30 scientific data sources, plus a growing suite of connected tools (research library, lab workflow, public site) under one unified login. Live in production with beta testing users, heading toward paid launch. We build carefully: PRs, review, tests, feature flags — quality over speed. Stack: React 18/Vite/TypeScript on Vercel · Supabase (Postgres + RLS + Deno edge functions, 3 projects) · Clerk (unified auth across subdomains) · Stripe · PostHog · Resend · LLM providers (Groq/Cerebras/Gemini) · GitHub. The product is bilingual English/Arabic (RTL) — you don't need Arabic (a plus!), but you need to build RTL-safe UI. What you'll do: First project (~2–4 weeks): production observability + automated bug pipeline. Integrate Sentry (including Seer auto-fix) across the Vercel apps and Supabase edge functions, connect it to our existing in-app feedback system and AI-assisted fix workflow (GitHub Actions + Claude Code — partially built), set up CI (tests on PRs, required checks), and write the runbook. Ongoing: build features from the designers specs, and progressively connect the product suite — shared components, cross-tool data bridges, one coherent experience across the tools. Every feature ships with tests, behind a feature flag where appropriate, documented, via PR. How we work: async-first with a biweekly video call; we are in US Eastern time . We use AI-assisted development heavily (Claude Code); you should be comfortable reviewing and hardening AI-written code. Detailed commit messages and PR descriptions are non-negotiable. Production incidents: we'll agree on a response-time expectation together and price it in. To apply (required — proposals that skip these are declined): -Start your proposal with the words "Ready to build". -Tell us about one production bug involving Supabase RLS, auth, or webhooks that you personally debugged — what was wrong and how you found it. -Given a live SaaS you've never seen, what are the first three things you'd review before writing any code, and why? -Your timezone + which hours (US Eastern) you can overlap. -Confirm you personally will write the code (no agency handoff) and can do a camera-on video call before hire.
