The opportunity
Security is at the foundation of OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity.
What you'll do
Own the architecture and roadmap for one or more core security services: (e.g., authN/Z, policy enforcement, secure proxies, key management), taking them from design to rollout to long-term operation.
Design and implement planet-scale security systems that provide strong: guarantees across hardware, operating systems, Kubernetes, networks, and CI/CD: balancing security, reliability, latency, and developer ergonomics.
Lead cross-functional launches with infrastructure and research engineering: teams, shaping interfaces, migration plans, and safe rollout strategies across large fleets and critical workflows.
Build or evolve security primitives (identity, attestation, authorization,: encryption key lifecycle, access mediation) that become platform building blocks for OpenAI.
Leverage frontier models and agents to develop automation and detection: tooling to continuously identify and mitigate risks in large-scale cloud and on-prem environments.
Lead design reviews and threat models for major initiatives, and drive closure on systemic issues.
What they're looking for
- Mentor engineers across InfraSec and partner teams, raising the bar on: engineering quality, operational readiness, and secure-by-default practices.
- Strong software engineering skills with a track record of shipping and: operating reliable distributed systems in production.
- Experience building or operating critical infrastructure, especially security: infrastructure, at planet scale (e.g., auth services, service-to-service proxies, certificate or key-management systems).
- Deep understanding of security principles, best practices, and common vulnerabilities.
