About the role

OpenAI seeks a Security Software Engineer to join the Infrastructure Security (InfraSec) team. The role designs and builds foundational security services for OpenAI’s high-scale infrastructure, including authentication, proxies, access brokers, and key management, across on-prem and cloud environments.

Responsibilities

  • 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.

Qualifications

  • Strong software engineering skills in Python, Go, Rust, or C/C++, with a track record of shipping and operating high-reliability distributed services.
  • 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).
  • A proactive mindset, with the ability to identify and address security gaps or inefficiencies through automation and tooling.
  • A track record of delivering scalable solutions and driving impactful changes across infrastructure in real-world projects.
  • Strong analytical and problem-solving skills, with an ability to think critically and objectively assess security risks.
  • Excellent communication skills, with the ability to convey complex security concepts to technical and non-technical stakeholders.
  • Excitement about collaborating with cross-functional teams to build secure, reliable systems that scale globally.
