About the role 💭

The Radar team builds our real-time identity intelligence layer that helps developers detect risk, prevent threats, and protect their apps. Radar ingests high-volume authentication and identity events, enriches them with signals, and powers workflows that customers use to take action: enforcing challenges, blocking suspicious behavior, or triggering reviews.




Our mission is to give developers a turnkey platform for identity security and risk evaluation — something that “just works” out of the box but is flexible enough to support sophisticated use cases.




Engineers on Radar care deeply about correctness, performance, observability, and the developer experience. The ideal candidate is excited by distributed systems, analytics, and safety features that meaningfully protect users.
