Responsibilities

  • Design, build, and operate Host Assurance platform components that establish trust in bare-metal and VM hosts before production use.
  • Ensure hosts remain verifiably trustworthy from hardware delivery and installation through secure bootstrap and orchestration readiness.
  • Build machine identity, certificate issuance and enrollment, HSM- or key-management-backed trust services, host attestation, measurement, and baseline verification tooling.
  • Validate hardware and firmware against vendor claims and detect and manage drift over time.
  • Eliminate insecure bootstrap patterns while partnering with provisioning, fleet, and orchestration teams on secure deployment paths.
  • Own components through implementation, operational readiness, launch, rollout, monitoring, recovery procedures, runbooks, and ongoing operation.
  • Participate in production support through an on-call rotation and define observable, testable security properties for host platforms.

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.
  • Ability to reason across services, APIs, host software, trust boundaries, correctness, and safe failure behavior.
  • Experience writing production-quality code and analyzing failure modes, operational safety, and long-term maintainability.
  • Experience supporting critical production systems at scale, such as through on-call responsibilities.
  • Experience with PKI, HSMs, machine identity, attestation, secure boot, or hardware security is valuable but not required.
  • Ability to work independently and collaboratively across infrastructure, research, provisioning, fleet, orchestration, hardware, and firmware disciplines.
