About Youmeverse

Youmeverse is a premium AI assistant built in Cameroon by Glenhalton (GDA Africa) — voice and text, English and French, paid for with MTN MoMo and Orange Money. One Expo codebase ships to web (installable PWA), iOS, and Android; the backend is Supabase edge functions and Cloudflare Workers. Small team, production users, real payments.

The role

You'll be an owner across the stack — from React Native UI to edge functions to the payment webhook — with AI development tools as a first-class part of the job. We work with Claude Code daily; you should be the kind of engineer who multiplies through these tools while staying accountable for every line that ships. You report directly to the founder and your code reaches users the week you write it.

What you'll do

  • Ship product features end to end: UI in Expo / React Native (web + native), state, edge functions, database migrations — the whole slice.
  • Build the AI layer: LLM orchestration and prompting, assistant memory, tool/agent workflows, and voice (TTS/STT) pipelines.
  • Own production quality: tests with Vitest, monitoring, honest post-mortems, and server-authoritative correctness for anything that touches money (Monetbil mobile-money payments, the token wallet).
  • Work the infra: Supabase (Postgres, RLS, edge functions), Cloudflare Workers, Firebase Hosting, and the PWA service-worker layer.
  • Use AI tooling seriously: Claude Code, Cursor, or similar are part of the workflow here — with the judgment to review, test, and own the output.
  • Shape the roadmap: small team means your technical opinions carry weight from day one.

What you'll bring

  • 3+ years building and shipping production software, with at least one product you can point to that real users used.
  • Strong TypeScript, and solid React or React Native — our entire stack is TypeScript-first, strict mode, no shortcuts.
  • Backend fluency: SQL and migrations, API design, auth, and reasoning about idempotency and race conditions (payments demand it).
  • Demonstrated proficiency with AI development tools — they're part of the job, not a shortcut. Show us how you work with them.
  • Production discipline: you write tests, you check your deploys, you say plainly what broke and why.
  • Self-direction — you'll get problems and context, not tickets.

Nice to have

  • Experience with LLM APIs (Anthropic, OpenRouter), streaming, prompt engineering, or agent frameworks.
  • Expo/EAS builds, PWA/service workers, or mobile-money/payment integrations.
  • French — the product is bilingual, and so are our users.
