Role
We are looking for a Browser Extension Engineer to join our team. This is a Hybrid (Bangalore) role, reporting to the Director, Threat Researcher in the Engineering department. Zero Trust Browser is our Browser Detection and Response (BDR) extension that lives inside Chrome, Firefox, and Safari to protect users where they actually work by detecting threats, enforcing enterprise policy, and analyzing content in real time without slowing anyone down.
This is not a typical frontend role; most of the work happens beneath the UI layer in code that runs on every page a user visits across browsers we do not control and websites we have never seen. The core engineering challenges center on the browser itself: how pages load, how extension contexts communicate, how to stay fast and invisible, and how to build controls that hold up against active evasion. You will join a small, senior team as a hands-on individual contributor, owning features end to end and shaping how a large, modular codebase grows.
