As a Senior Rust Engineer at Bitwarden, you will be responsible for building new features and maintaining the various cross platform SDKs for our Password Manager and Secrets Manager products. We’re looking for someone who will thrive in a growing organization with a strong collaborative focus. You will have the opportunity to take ownership over a key area of our products, providing direction for future changes and scoping out work to bring exciting new features to our user and developer communities while maintaining overall code quality and maintainability.
RESPONSIBILITIES
Platform & Feature Development: Design, build, and maintain high-performance APIs, SDKs, and CLIs for Secrets Manager and our future AI Identity and Access security frameworks [cite: bitwarden_teams_charter_strategy.md].
Machine & AI Identity Custody: Implement secure, zero-knowledge machine authentication, scoped access tokens, and runtime secrets injection gateways that protect credentials from being exposed to parent AI models or local execution environments.
Decoupled Architecture: Work within our Decoupled Platform Architecture to ensure Secrets Manager operates as a highly scalable, independent tenant using its own dedicated data stores and asynchronous event-driven message networks [cite: elt-modernization-blueprint.md].
End-to-End Ownership: Own the automated testing, deployment pipelines, and production SRE health of your team's services, participating in on-call rotations and postmortem analyses to drive continuous operational improvement [cite: elt-modernization-blueprint.md].
Developer Usability: Build usable, highly developer-friendly API endpoints, integration libraries, and comprehensive technical documentation to lower the friction of secrets enrollment and machine onboarding [cite: bitwarden_teams_charter_strategy.md].
Overall Experience: 6-10 years in Software Engineering
Technical Stack: Strong proficiency and experience in AI-Led Development in Rust, C# / .NET, or TypeScript (our core Secrets Manager SDK is built in Rust).
Identity & Secrets Management: Practical experience designing or integrating machine identity platforms, vaulting services, OAuth/OIDC, or token-based authorization structures (e.g., JWT, access tokens, API keys).
AI/Agent Security Interest: Curiosity or experience with the security implications of AI agent architectures, large language model (LLM) memory isolation, or sandboxed execution environments.
T-Shaped Engineering Mindset: Experience writing robust automated integration tests, maintaining containerized environments (Docker/Kubernetes), and using modern APM and SRE logging tools (e.g., Azure Monitor, Grafana) to monitor services in production [cite: Transforming Engineering Through Ownership].
Cryptographic Foundations: Solid grasp of symmetric/asymmetric encryption, zero-knowledge protocols, and OS-level secure storage APIs [cite: Transforming Engineering Through Ownership].
Collaborative Mindset: Excitement to work in a high-velocity, outcome-driven environment using rapid prototyping and data-driven prioritization [cite: elt-modernization-blueprint.md].
Open Source & Communication: Excellent written communication and a strong passion for open-source software, developer tooling, and modern internet security [cite: Transforming Engineering Through Ownership].
