Software Engineer, Host AssuranceActive$266K–$445K

The opportunity

Security is foundational to OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity.

What you'll do

  • Design, build, and operate components of the Host Assurance platform that: establish trust in both bare-metal & VM hosts before they are eligible for production use.

  • Help ensure hosts are verifiably trustworthy from delivery and installation: through secure bootstrap and readiness to join orchestration systems.

  • Build and improve systems such as machine identity, certificate issuance and: enrollment, HSM-backed or key-management-backed trust services, host attestation, measurement, and baseline verification tooling.

  • Validate delivered hardware and firmware against vendor claims and: continuously detect and manage drift over time.

  • Eliminate insecure bootstrap patterns while preserving deployment throughput: and operational reliability. Partner with provisioning, fleet, and orchestration teams to deliver paved paths where the secure approach is the easiest approach.

  • Own software components through implementation, operational readiness,: launch, and ongoing operation. Define readiness criteria, validate behavior under load and failure, establish monitoring and actionable alerts, plan staged rollouts and tested recovery procedures, and maintain runbooks. Use production experience to improve reliability and reduce operational burden.

What they're looking for

  • Participate in production support via oncall rotation.
  • Help define observable, testable security properties for host platforms and: improve the telemetry and validation needed to enforce them in practice.
  • Work across different deployment models and provider boundaries while: maintaining a consistent bar for host trust outcomes.
  • Have strong software engineering experience building and operating reliable production systems at scale.
