Operating as a fully remote global team, we are on a mission to protect digital lives and ensure anonymity for millions worldwide. We are vocal advocates for civil rights, digital freedom, and an uncensored online culture.
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.
- Strong TypeScript (strict) - BOTH browser and Node.js.
- Hands-on browser extension development, Manifest V3.
- Backend: Node.js, REST APIs, third-party API integration, webhooks.
- UI: React or Preact.
- Solid understanding of web security fundamentals (CSP, CORS, XSS, secure storage).
- Git, CI/CD, modern build tooling (Vite or equivalent).
Nice to Have
- Experience with extension frameworks (WXT, Plasmo or other).
- Cross-browser extension delivery (Firefox, Edge).
- Background in security, anti-phishing, or privacy products.
- Familiarity with threat-intelligence feeds or DNS-level filtering.
- Prior Chrome Web Store publishing experience.
Stack:
TypeScript · Manifest V3 · WXT/Plasmo · Preact · Node.js · Vite · Vitest/Playwright

- Build personal AI agents using our premium infrastructure.
- Absolute freedom to work from any location (GMT+1– GMT+5).
- Internal R&D opportunities.
- Paid time off and sick leave.
- Direct impact on a massive, world-class B2C product.
