What Bunkyr does

Bunkyr enables companies to protect their users’ data with a simple, hardware-secured API. When a user forgets their password, applications using Bunkyr can provide them a familiar, robust recovery method to restore access to encrypted data. Zero-Knowledge architectures and end-to-end encryption are the only true safeguards against data breaches, but come with large user-experience burdens and engineering overhead. Bunkyr eliminates these obstacles in a way that is friendly to both developers and users, cost-effective, and extremely fast. Users won’t even know Bunkyr exists, while their data stays protected against both breaches and lost passwords.

No open roles recorded right now.

That does not mean they are not hiring — plenty of roles never reach a job board. The careers page below is the earliest place a new opening appears.

Check the company’s own careers page — linked at the top — before a job board. A role appears there first, sometimes weeks before it is syndicated anywhere else.
