Lead Full Stack Engineer — Users & Auth We're looking for a Lead Full Stack Engineer to own 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 end-to-end: 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. 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: • Owning auth end-to-end: architecture, implementation, and Auth0 integration across frontend and backend • Leading a multidisciplinary team — sprint planning, standups, retros • Elevating the team through pairing, mentorship, and sharing what you know • Setting and holding the quality bar — through code reviews, design reviews, and your own work • Reviewing product specs from the technical lens — flagging feasibility gaps and spotting where AI tooling can close work that would otherwise take months Who you are • 5+ years of software engineering experience with solid execution in production environments • 2+ years of hands-on experience implementing authentication and authorization with Auth0 or comparable identity platforms • Strong in Java and Spring on the backend, with solid frontend experience — React preferred • Solid understanding of security best practices for web applications and secure software design in distributed architectures • A technical product mindset grounded in security — you know how to balance velocity with the constraints of owning critical systems • High autonomy, proactivity, and ownership mindset. You don't wait for direction — you spot what needs to happen and drive it • A genuine pull toward AI. You don't need to be an expert, but you're actively experimenting with AI tools in your day-to-day work, keep up with where the space is going, and are eager to apply it to how we build. At Clara, AI is part of how we work, not a side topic • English proficiency, with the ability to lead technical discussions across geographies We've kept this l
