Senior Auth Engineer — Users & Auth

We're looking for a Senior Auth Engineer to own, architect, and build the systems that define how users exist and move within Clara's platform — authentication, authorization, identity, and access control. This is one of those roles where the work is invisible when it's done right and critical when it's not. The scope is deep and end-to-end: architecting the identity layer, designing auth flows, managing the user lifecycle, integrating Auth0 with Clara's platform, and making sure the frontend and backend sides of identity speak the same language. You'll be the person the rest of engineering turns to when there's an auth question no one else can answer. Security isn't a checklist here — it's a first-class concern baked into how we build.

We move fast and trust our engineers to own outcomes end-to-end. That means autonomy to make decisions, proactivity to surface problems before they become blockers, and the attitude to push initiatives across the finish line without waiting to be told what to do.

Your responsibilities will include:

Architecting and building identity and access as a shared platform capability that Clara's apps build on — making the design decisions that scale across products and turning them into working systems
