## Description

OpenAI is seeking a Software Engineer, Host Assurance to build and operate the services, APIs, and host software that establish and maintain trust in our compute infrastructure.

The base pay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience. The salary range for this position is $266K – $445K, with generous equity, performance-related bonus(es) for eligible employees, and a comprehensive benefits package.

The Security organization protects OpenAI’s technology, people, and products by building and operating deeply technical systems that must work reliably at massive scale. The Host Assurance team exists to make bare metal and VMs dependable & scalable foundations for OpenAI: secure by default, verifiable in practice, and resilient across providers and operating models.

Responsibilities:

- 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.

- Own software components through implementation, operational readiness, launch, and ongoing operation.

- 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.

Requirements:

- Strong software engineering experience building and operating reliable production systems at scale.

- Depth in distributed systems, backend or platform engineering, operating systems, or infrastructure security.

- Experience with PKI, HSMs, machine identity, attestation, secure boot, or hardware security is valuable but not required.

- Ability to reason across services, APIs, and host software, and learn the boot, firmware, and hardware trust mechanisms relevant to your work.

- Experience writing production quality code and ability to reason clearly about failure modes, operational safety, and long-term maintainability.

- Experience supporting critical production systems at scale, such as being on-call.

Benefits:

- Medical, dental, and vision insurance for you and your family, with employer contributions to Health Savings Accounts

- Pre-tax accounts for Health FSA, Dependent Care FSA, and commuter expenses

- 401(k) retirement plan with employer match

- Paid parental leave

- Paid time off

- 13+ paid company holidays

- Mental health and wellness support

- Employer-paid basic life and disability coverage

- Annual learning and development stipend

- Daily meals in our offices, and meal delivery credits as eligible

- Relocation support for eligible employees
