Software Engineer, HSM Infrastructure Security, Consumer DevicesActive$347K–$445K

The opportunity

We are hiring a Security Software Engineer to design and implement the hardware-backed security foundations used across OpenAI’s device ecosystem.

What you'll do

  • Design and implement security-critical software and firmware for HSMs, secure: elements, trusted execution environments, and hardware roots of trust.

  • Build and harden the policy-to-HSM boundary responsible for authorizing: certificate issuance and cryptographic signing operations.

  • Develop HSM trusted applications, firmware components, host interfaces,: device drivers, SDKs, or cryptographic service integrations.

  • Implement or extend cryptographic interfaces such as PKCS#11, OpenSSL: providers or engines, platform key-storage APIs, or comparable hardware-security interfaces.

  • Build firmware and software that cryptographically enforces key generation,: provisioning, usage, rotation, recovery, and destruction policies.

  • Design and implement HSM-backed certificate authority, code-signing,: key-management, and device-identity systems.

What they're looking for

  • Develop end-to-end cryptographic protocols spanning devices, secure hardware,: policy services, and backend infrastructure.
  • Build security capabilities supporting device attestation, secure boot,: factory provisioning and restoration, user registration, and authentication.
  • Design controls that make trusted software and policy changes verifiable,: auditable, and subject to appropriate multi-party authorization.
  • Write, review, test, and audit secure embedded software for resource-constrained environments.
