Senior Front End Software Engineer (Autofill)

One of the most critical parts of the Bitwarden product is our autofill and form detection. These features are a part of the Bitwarden browser extension, and they enable the extension to fill form fields with the user’s data and detect new logins to store in Bitwarden. We are looking for a Front-End Engineer to join a team that is responsible for maintaining and continually improving these parts of our product, ensuring that they grow to provide seamless integration with the latest web UI patterns across all browsers.

Unlike a typical front-end role, this work is rooted in low-level browser mechanics. Autofill behavior varies across browsers, and diagnosing issues often requires deep investigation into how individual browsers handle the DOM, content scripts, and form events. Changes in this area can have broad effects across the codebase, so patience and a methodical approach are as important as technical depth. This engineer will also help shape how we bring more automation and agentic practices into the way we build and ship software.
