The API/IAM team is a high‑visibility team responsible for Core Weave’s identity platform and the Core Weave API. We design and operate the authentication, authorization, account‑management, and access‑control services that every Core Weave product relies on. We own the interfaces that give customers programmatic control over their cloud resources, including REST/gRPC endpoints, Infrastructure‑as‑code, and more.

As the Engineering Manager for API/IAM, you will lead, mentor, and scale a distributed team of backend engineers working at the intersection of security, platform architecture, and developer experience. Some of what you’ll work on:

• Lead & grow the team – coach 6‑10 backend engineers, set clear goals, run regular 1‑on‑1s, and foster an inclusive, high‑performance culture.
• Own the API/IAM roadmap – partner with product, security and engineering teams to define and sequence work on authentication, authorization, identity primitives, service tokens, and first‑class developer APIs.
• Guide technical direction – facilitate design reviews, unblock complex architecture decisions, and ensure that our identity and edge services are scalable, secure, observable and efficient.
• Raise the engineering bar – drive test strategy, CI/CD hygiene, on‑call quality, and post‑incident learning so production health stays “five nines” strong.
• Hire for hyper‑growth – partner with recruiting, and lead interviews to expand the team’s capacity and skill diversity.
• Deliver business outcomes – define and track OKRs, balance tech‑debt vs. features, and communicate progress to senior leadership and stakeholders.

We’re looking for a thoughtful leader who blends technical depth with strategic vision, and thrives in fast-moving, high-growth environments. If you value clarity over complexity, mentorship over management, and resilience over rigidity, you’ll fit right in.

• At least 2 years of experience in engineering leadership roles.
• Track record of shipping and operating APIs and/or identity platforms using Go, Python, or Type Script.
• Deep understanding of authentication, authorization, and IAM best‑practices (SAML, OIDC, OAuth, RBAC, etc).
• Solid grasp of CI/CD, observability, databases and secure SDLC principles.
• Excellent written & verbal communication—you translate technical trade‑offs for executives and engineers alike and drive alignment across functions.
• Passion for developing people, crafting a psychologically safe environment, and modeling Core Weave’s values in day‑to‑day leadership.

• Experience leading teams that build cloud platform services on Kubernetes (operators, CRDs, admission webhooks, etc.).
• Demonstrated success hiring and scaling teams during hyper‑growth or rapid product expansion.
• Familiarity with multi‑region, high‑throughput identity or access‑control pipelines.
• Hands‑on background with Infrastructure‑as‑Code (Terraform, Pulumi) and major clouds (AWS, GCP, Azure).
• Prior ownership of SLO/SLA definition and end‑to‑end telemetry pipelines for identity and access services (e.g., auth latency, token issuance…
