About the role

Security Engineer building trust foundations for bare-metal platforms at OpenAI. Designing and operating core security infrastructure for reliable compute platforms across global infrastructure.

Responsibilities

Design, build, and operate components of the Host Assurance platform that establish trust in bare-metal 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.
Contribute code, reviews, operational improvements, and design guidance for foundational trust services that must be dependable at scale.
Help define observable, testable security properties for host platforms and improve the telemetry and validation needed to enforce them in practice.
Participate in incident response, debugging, and post-incident improvements for security-critical infrastructure.
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.
Have deep expertise in at least one relevant domain such as PKI, HSMs, machine identity, applied cryptography, secure boot, firmware or hardware security, host attestation, or low-level platform security.
Are comfortable working across systems boundaries, from services and APIs down to host, boot, firmware, or hardware-adjacent trust mechanisms.
Can write production quality code and reason clearly about failure modes, operational safety, and long-term maintainability.
Have experience replacing fragile or manual security mechanisms with durable, paved-path infrastructure.
Balance rigor with pragmatism, and care about making strong security controls deployable in real-world environments.
Are self-directed, low ego, and willing to work across disciplines to solve the most important problems.
Enjoy building in ambiguous spaces where the architecture is still emerging, stakes are at all time high, and the future is being built.
