Bitwarden promotes better internet security and safety with the leading open source password management solution for individuals, teams, and business organizations. Our philosophy on security is that “we are all in this together” – we continue to offer a full-featured free version of Bitwarden so that everyone can be protected with solid password management. We also provide enterprise-grade solutions to some of the largest companies in the world, and will continue to innovate in the identity and authentication market as the world starts to grow beyond passwords.

As a Senior Rust Engineer on the Passkeys team, you will build the technology taking the world beyond passwords. Bitwarden is a credential provider across browser, desktop, and mobile, and the Passkeys team owns our implementation of WebAuthn and FIDO2 — creating and asserting credentials, integrating with each platform's credential provider APIs, and the emerging standards for moving credentials between providers so that users are never locked in.




This is a standards and systems engineering role. The work is written primarily in Rust, in the shared SDK consumed by every Bitwarden client, and it demands unusual precision: you will implement specifications where a subtle misreading produces a credential that fails to work on one relying party out of a thousand, and you will do it inside a zero-knowledge, end-to-end encrypted architecture where the private key material can never be exposed to our servers.
WHAT YOU WILL DO
Design, build, and maintain Bitwarden's implementation of the WebAuthn and FIDO2 standards in Rust, including credential creation, assertion, and storage within an end-to-end encrypted vault
Integrate our passkey implementation with each platform's credential provider surface across browser, desktop, and mobile clients
Participate in the hands-on design, development, and evolution of the shared Rust SDK, including language bindings and FFI, consumed across al
