# Hardware / Low Level Security Engineer

- **Company:** Cerebras Systems
- **Location:** United States
- **Contract:** Permanent contract
- **Skills:** Artificial Intelligence, Booting (BIOS), Cyber Security, Firmware, Linux Kernel, Software Systems, Extensible Firmware Interface, U-Boot
- **Published:** July 24, 2026
- **Apply:** https://www.indeed.com/viewjob?jk=afe1f331c043f62b

## About the Role

* Background in Mechanical and/or Electrical Engineering with career focus in Cybersecurity.

 * Deep familiarity with the Linux kernel - including kernel modules, syscall interface, 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 (Rust, Go, or similar), with the ability to read and write production kernel code.

 * Familiarity with hardware-level isolation primitives (e.g., IOMMU, SR-IOV, confidential computing); exposure to non-standard compute architectures a plus.

 * Strong written communication skills, with the ability to make low-level security concepts approachable for non-specialists.

## Description

We are seeking a Hardware / Low Level Security Engineer to harden the foundational layers of the systems that run the fastest AI inference on earth. You will work close to the metal - across the Linux kernel, firmware, secure boot, and hardware roots of trust - to identify weaknesses, build defenses, and partner with platform and infrastructure teams to ship low-level security improvements. The right candidate brings deep systems expertise, a security mindset shaped by hands-on hardening and exploitation, and a passion for protecting unique compute architectures at scale.

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 Cerebras compute platforms.

 * Drive secure boot, measured boot, and attestation strategies across our infrastructure, from the wafer-scale system 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 (e.g., eBPF) to enable detection of low-level attacker behavior.

 * Stay ahead of 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.
