The opportunity
Crusoe is on a mission to accelerate the abundance of energy and intelligence . As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads.
What you'll do
Own IAM Architecture & Direction: Set and own the multi-quarter architecture for the fine-grained authorization model, authentication and federation, and identity lifecycle that secure every request in Crusoe's AI cloud.
Define Platform-Wide Standards: Own the identity primitives, authorization patterns, and guardrails that keep access control consistent and secure across the entire Crusoe Cloud platform.
Drive Build-vs-Buy & Framework Decisions: Lead evaluation and adoption of core IAM technologies, making durable, well-reasoned decisions.
Solve the Hardest, Highest-Risk Problems: Take on ambiguous, high-blast-radius initiatives such as scaling the authorization hot path, multi-tenancy, and tenant isolation, balancing security, reliability, and latency.
Stay Hands-On: Remain deeply technical: write and review code on the most critical and complex paths, and set the engineering quality bar through your own work.
Lead Through Influence: Drive cross-team technical alignment, author design reviews and RFCs, and steer execution across multiple teams without direct authority.
What they're looking for
- Champion Security at Scale: Lead threat modeling and secure-by-design practices for systems on the critical path of every request.
- Multiply the Team: Mentor senior and mid-level engineers, raise the engineering bar, and shape hiring, onboarding, and technical strategy.
- Education & Experience: Bachelor's degree in Computer Science or a related field (or equivalent practical experience), 8+ years of software engineering experience building production distributed systems in Go, including significant experience with identity, authorization, or other security-critical systems, and a track record of leading the design of large-scale systems.
- Architectural Leadership: Demonstrated ability to set technical direction and deliver complex, fault-tolerant distributed systems and managed cloud services across multiple teams.
