Software Engineer, Infrastructure SecurityActive$230K–$385K

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

  • Architect and implement production-grade security services (e.g., auth: services, access brokers, secure proxies, key-management infrastructure) that provide strong guarantees across hardware, operating systems, Kubernetes, networks, and CI/CD.

  • Partner with infrastructure and research engineers to embed security into: high-performance compute clusters, enabling rapid model training and deployment without compromising protection.

  • Develop automation and detection tooling to continuously identify and: mitigate risks in large-scale cloud and on-prem environments.

  • Drive high-impact initiatives such as line-speed encryption, machine: identity, and network isolation, continuously raising the security bar for emerging AI workloads.

  • Lead or participate in design reviews and threat models to ensure new systems: launch with strong security foundations and operational excellence.

  • Strong software engineering skills in languages such as Python, Go, Rust, or: C/C++, with a track record of shipping and operating high-reliability distributed services.

What they're looking for

  • Experience building or operating critical security infrastructure (e.g., auth: services, service-to-service proxies, certificate or key-management systems).
  • Deep understanding of security principles, best practices, and common vulnerabilities.
  • Expertise in securing large-scale cloud platforms (e.g., Azure, AWS, GCP),: including multi-cloud networks and cloud-agnostic system design.
  • Familiarity with container and orchestration security (Kubernetes, service: meshes) and modern authentication/authorization standards (OIDC, mTLS, SPIFFE/SPIRE).
