As a Lead Engineer for our Passkeys team you will be responsible for leading the technical direction and supporting the engineering effort of a team focused on building and maintaining Bitwardens WebAuthn credential provider implementation across browser desktop and mobile. The Passkeys team owns our implementation of WebAuthn and FIDO2 - creating and asserting credentials integrating with each platforms credential provider APIs and the emerging standards for moving credentials between providers so that users are never locked in.

You will be expected to own and understand the entirety of the teams domain and be able to support the other engineers on the team as well as engage in well-reasoned discussions with other technical leaders in the organization.

WHAT YOU WILL DO

• Design build and maintain Bitwardens 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 platforms 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
• Work closely with your manager to maintain the technical roadmap for the team ensuring that core platform dependencies are up to date and emerging technologies are considered for potential adoption.
• Unblock and support other engineers on the team.
• Collaborate with other Tech Leads to ensure that cross-team technical direction is aligned when initiatives span team boundaries.
• Serve as a representative of the team in technical discussions and be able to speak authoritatively about your domain.
• Set the example for thorough code reviews using them to spread knowledge on the team and ensure high standards for code quality.
• Occasionally review & approve bug fixes submitted by the user community

WHAT YOU BRING

• 8 years of experience as lead or team lead. Experience designing and implementing complex user interaction flows in Angular applications and native OS (Windows MacOS Linux) including developing against native OS APIs.
• 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.
• A bias for long-horizon thinking ensuring that decisions made today build stable and maintainable tooling for the future.
• Experience on a Platform team where other teams are your customers and you are responsible for ensuring that their feature development can be done with tooling as a support and not a hindrance.
• Experience using AI tooling in your development and testing workflow (Anthropic Claude preferred)
• 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
