About the role

Responsibilities

  • Partner with platform, infrastructure, and hardware teams to embed security controls from physical hardware through runtime.
  • Design and implement security hardening across the Linux kernel, bootloader, firmware, and host OS layers of compute platforms.
  • Drive secure boot, measured boot, and attestation strategies across infrastructure, from wafer-scale systems to supporting host nodes.
  • Conduct deep security reviews of kernel modules, drivers, and low-level system components, identifying and remediating memory safety, privilege escalation, and isolation issues.
  • Develop kernel-level monitoring and telemetry, such as eBPF, to enable detection of low-level attacker behavior.
  • Monitor emerging kernel CVEs, supply chain risks, and hardware-level threats, driving response and remediation across the fleet.
  • Document low-level security posture, threat models, and remediation playbooks in clear, accessible language.

Requirements

  • Background in Mechanical and/or Electrical Engineering with a career focus in cybersecurity.
  • Deep familiarity with the Linux kernel, including kernel modules, syscall interfaces, namespaces, cgroups, eBPF, and LSM.
  • Hands-on experience with firmware, UEFI, secure boot, TPM, and platform integrity tooling.
  • Strong proficiency in C and a modern systems language such as Rust or Go, with the ability to read and write production kernel code.
  • Familiarity with hardware-level isolation primitives such as IOMMU, SR-IOV, and confidential computing.
  • Strong written communication skills, with the ability to make low-level security concepts approachable for non-specialists.

Nice to Have

  • Exposure to non-standard compute architectures.
