Roles & Responsibilities

As a founding member of the Browser Stack team, you'll build and harden the custom browser and automation layer that the hardest targets on the web can't tell apart from a real user. This is a fast-moving frontier — detection surfaces shift weekly, and the browser you ship is the difference between data flowing and data stopping. In particular, you will:

• Engineer the internals of our custom browser and defeat fingerprinting and antibot detection at the deepest layers of the stack
• Extend the stealth frontier across new engines and mobile profiles
• Build our own automation client to run and control the browser at scale on the toughest sites
• Create the introspection and tracing tooling that turns days of manual ban investigation into a readout in minutes
• Harden the release pipeline so browser updates never ship silent success-rate cliffs
• Push browser performance to keep pace with the fastest headless and cloud browser platforms
• Help shape the team's technical roadmap and contribute back to open source browser development

Requirements

• Extensive experience in C++ and TypeScript
• Previous experience contributing to the source code of an open source browser project such as Chromium, WebKit, or Firefox
• Good understanding of Web APIs (for example canvas, audio, WebGL, WebRTC)
• Deep understanding of operating systems, plus knowledge of emulation and virtualization
• A good understanding of the TCP/IP stack as well as HTTP and SOCKS protocols
• A good understanding of containerisation concepts (Docker, containerd, runc, K8s)
• Experience with Rust
• Experience building and deploying production applications
• A good understanding of browser fingerprinting approaches

Bonus points for

• Being a core committer to any of the major browser projects
