Job Summary

A hands-on security engineering role focused on building and operating the Host Assurance platform to establish trust in bare-metal hosts across OpenAI’s global infrastructure. You’ll work across hardware, firmware, and software boundaries to ensure secure bootstrap, attestation, and measurable trust while enabling scalable production deployments.

Location: San Francisco, Seattle

Workplace: Hybrid

Employment Type: Full time

Job Function: Cybersecurity

Key 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.

Pay and Benefits

Salary: USD 293,000 - 385,000 annually

Equity and Bonus:Equity

Key Requirements

•5+ years of software engineering experience building and operating reliable production systems at scale.
•Deep expertise in PKI, HSMs, machine identity, applied cryptography, secure boot, firmware or hardware security, host attestation, or low-level platform security.
•Comfortable working across systems boundaries, from services and APIs down to host, boot, firmware, or hardware-adjacent trust mechanisms.
•Ability to write production-quality code and reason clearly about failure modes, operational safety, and long-term maintainability.
•Experience replacing fragile or manual security mechanisms with durable, paved-path infrastructure.
