- 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 all Bitwarden clients
- Implement and help shape emerging standards for credential portability and secure import and export between providers
- Build the interoperability testing that keeps our implementation correct against the long tail of relying parties, browsers, and platforms our users encounter in the real world
- Become an expert on the Bitwarden APIs and the cryptographic and architectural constraints of a zero-knowledge product
- Participate in code reviews, learning, and spreading technical knowledge
- Independently plan, estimate, and deliver new feature work and bug fixes
- Occasionally review & approve bug fixes submitted by the user community
WHAT YOU BRING TO BITWARDEN
Expertise in developing and maintaining production Rust components, including the design and application of libraries, language bindings, and FFI
Experience implementing a standard or protocol from its specification, and the discipline that requires — reading the spec closely, handling the edge cases, and testing against real-world implementations rather than assuming conformance
Working knowledge of applied cryptography — you can reason about public key cryptography, signatures, and key handling, and you know where the sharp edges are
A rigorous approach to correctness — you write readable, testable code, and you think carefully about failure modes in software that handles sensitive data
Experience using AI tooling in your development and testing workflow (Anthropic Claude preferred)
Experience with Electron, TypeScript, and other web tech for cross-platform desktop applications and web clients is a plus
Collaborative and adaptable mindset
Openness and authenticity combined with excellent communication skills
Excitement and enthusiasm for open source and for better internet security
Excellent problem-solving skills – you might not know all the answers, but you know how to find and communicate the solution
