## About the Role

* 8+ years of relevant professional experience building scalable, distributed backend systems, with a track record of driving architecture end to end.
 * Deep expertise in identity and access management - authentication, authorization, and access-control models such as RBAC, ABAC, or risk-based access control.
 * Hands-on experience with several of: PKI and certificate/key lifecycle management, mTLS, SPIFFE/SPIRE or comparable workload-identity systems, service mesh, secret management (e.g., Vault), and privileged access management (PAM).
 * Proficiency in at least one systems language such as Go, Rust, Java, C++, Python, or C# .NET, and a habit of building systems rather than only configuring vendor tools.
 * Experience leading the technical work of other engineers - setting direction across teams, writing influential design docs, and mentoring senior talent.
 * AI fluency: you use AI tools in your daily workflow, understand LLM capabilities and limitations, and can reason about what it means to give an AI agent an identity and permissions.
 * A Bachelor's degree or equivalent experience in Computer Science, Computer Engineering, or a similar technical field.

You are

 * A systems thinker. You reason about failure modes, blast radius, and reliability, and you design access that stays secure and available even when dependencies fail.
 * Security-minded and pragmatic. You are passionate about least privilege and zero trust, but you optimize for the Builder experience and adoption, not controls for their own sake.
 * A force multiplier. You make the engineers and teams around you better through mentorship, clear writing, and high-quality technical leadership.
 * A strong communicator. You translate deep technical tradeoffs for both engineers and executives, and you build alignment across organizational boundaries.
 * Bar-raising and hands-on. You still love to build, and you set the standard for engineering quality on the hardest problems.
