We build specialized Chrome extensions for professional users of AI tools such as ChatGPT.


Our focus is on high-performance, well-architected browser extensions that deliver real productivity value — not experiments or gimmicks.


We are looking for an experienced Chrome Extension Developer who understands how to design, build, and maintain production-ready browser extensions.


Tasks

  • Develop and maintain modern Chrome extensions

  • Build UI components for browser environments (content scripts, popups, options pages)

  • Work with Chrome Extension APIs (Manifest V3)

  • Integrate external APIs and manage browser storage (local / sync)

  • Optimize performance, reliability, and code quality

  • Prepare and manage releases for the Chrome Web Store

  • Collaborate closely on product and technical decisions (not just ticket execution)


Requirements

  • Strong experience with JavaScript / TypeScript

  • Proven experience building Chrome Extensions (Manifest V3 required)


Solid knowledge of:



  • Content Scripts

  • Background / Service Workers

  • Chrome Storage APIs


And



  • Experience with modern frontend frameworks (React, Vue, or well-structured Vanilla JS)

  • Strong understanding of clean, maintainable code

  • Independent and structured working style

  • Very good English or German skills


Benefits

  • Work on real products with paying users

  • Clear technical ownership — no agency chaos

  • Fast decision-making and direct communication

  • Modern tech stack

  • Long-term collaboration opportunities

  • Competitive payment based on experience


If you see Chrome extensions as serious software products — not side projects — we would love to hear from you.


Please include links or references to Chrome extensions you have built or contributed to.
