Role
Build the MVP of a security-focused browser extension and its supporting backend - from architecture to store release. Single-owner role: you ship the extension end to end via AI assisted dev.

What you will do
- Develop a Chrome(other) extension on Manifest V3 (service workers, content scripts, popup/options UI).
- Build and maintain the backend services powering the extension (API, threat-intelligence integrations, webhooks).
- Integrate third-party security APIs (e.g. Google Safe Browsing, breach-data sources).
- Own the full release cycle: build pipeline, Chrome Web Store submission and review process.
- Implement client-side caching, secure storage, and a privacy-respecting data flow.
- Write tests (unit + E2E) and maintain code quality.

What we are looking for
- 3+ years full-stack development, production experience.
- Deep knowledge of TypeScript.
- Hands-on browser extension development, Manifest V3.
- Backend: Node.js (Fastify/Express), ORM (Prisma or Drizzle), SQL, Supabase, REST APIs, third-party API integration, webhooks.
- UI: Nuxt/Vue.
- Solid understanding of web security fundamentals (CSP, CORS, XSS, secure storage).
- Git, CI/CD, modern build tooling, experience with monorepo.
- AI agents driven workflow.

Nice to Have
- Cross-browser extension delivery (Firefox, Edge).
- Background in security, anti-phishing, or privacy products.
- Familiarity with threat-intelligence feeds or DNS-level filtering.
- Chrome Web Store publishing experience.
- Experience with Stripe, Twilio (A2P), AWS SES, Web Risk, HIBP integration.
