Lightpanda develops an open-source headless browser designed for machines, used for web automation, crawling and AI agents rather than for human browsing. The engine is written from scratch in Zig, is not based on Chromium, Blink or WebKit, runs JavaScript without rendering pages, and in its own benchmark ran 9 times faster with 16 times less memory than headless Chrome while staying compatible with Puppeteer and Playwright through CDP. The French company was founded in 2022 by Francis Bouvier, raised a pre-seed led by ISAI in 2025 and a $4.5 million seed round in January 2026.

About Lightpanda

Lightpanda is building a headless web browser from scratch, tailor-made for machine usage.

Our mission is to redefine web interaction by enabling AI agents, large-scale scraping, and automated workflows to run faster, smarter, and more efficiently, without the constraints of legacy browsers.

We're an ambitious team with a strong open-source foundation, led by experienced founders with a successful startup exit history, and we're now funded.

You'd be joining our team at an early stage, with equity incentives that reflect that.

About this role

We’re seeking a skilled and diligent full-time software engineer to join our growing team. You will work as part of the engineering team to develop our open-source headless browser.

What you will do:

  • Work as part of a team of engineers to design, build, test, and document the browser
  • Improve the quality, efficiency, scalability, and stability of the browser
  • Improve the binding framework with V8 JS engine
  • Implement Web APIs and Chrome Devtools Protocol in Zig

What we’re looking for:

  • Experience with system programming/low level language Zig, C++, C
  • Familiarity with Web APIs and front-end JS technologies
  • Comfortable working on an open source project and interacting with the community
  • Familiarity with the internals of JavaScript runtimes (v8 or other) is a plus
  • Ability to give and process constructive feedback, as well as work independently
  • Flexibility to adjust to the dynamic nature of a startup
