Data security for the agentic enterprise. Cyberhaven traces data's full lifecycle and adapts protection as context changes, everywhere work happens. Backed by Redpoint.
About the role
Cyberhaven is redefining data security by understanding how data flows across organizations. Our browser extension is a critical component of this vision, enabling visibility and control at the point where users interact with web applications. We’re looking for an experienced engineer to help build and enhance our extension, ensuring it’s secure, performant, and deeply integrated with our platform.
What they're looking for
- You have extensive experience in software engineering: coding, testing, debugging, and automating complex TypeScript/JavasScript applications
- You're comfortable digging into third-party web applications you don't control — inspecting network traffic, DOM structure, and client-side code to understand how a page works
- You have the ability to learn new technologies quickly and are eager to do so — especially as browser extension platforms and manifest specs continue to evolve
- You focus on correctness, performance, and reliability of background processes
- You have excellent communication skills,
- You are able to work self-sufficiently at times with minimal direction
