About The Position

As a Senior Full Stack Engineer on the Data Insights and Reporting (DIRT) team at Bitwarden, your work will directly impact how enterprise administrators understand the security posture of their organizations. You'll build the reports, dashboards, and integrations that turn vault data and activity into actionable intelligence, surfacing at-risk credentials, mapping who has access to what, protecting users from phishing attacks directly in the browser, and streaming events into the SIEM and collaboration tools security teams already rely on. This role combines deep front-end craft, backend API and data work, and the challenge of building meaningful insights on top of a zero-knowledge, end-to-end encrypted product. Working within Bitwarden's open-source ecosystem, you'll collaborate with a passionate community dedicated to transparency and trust in security software while contributing to our mission of making security accessible to everyone. This is an all-remote team and we're looking for someone located in the U.S. We do not offer visa sponsorship at this time.

Requirements

Extensive experience with .NET Core and C# for backend services
Strong proficiency with Angular, TypeScript, and RxJS for front-end development

Collaborative and adaptable mindset 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
