Job Application for Hardware / Low Level Security Engineer at Cerebras Systems

Back to jobs New Hardware / Low Level Security Engineer Remote, California, United States; Sunnyvale CA or Toronto Canada

Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. Our novel wafer-scale architecture provides the AI compute power of dozens of GPUs on a single chip, with the programming simplicity of a single device. This approach allows Cerebras to deliver industry-leading training and inference speeds and empowers machine learning users to effortlessly run large-scale ML applications, without the hassle of managing hundreds of GPUs or TPUs.

Cerebras' current customers include top model labs, global enterprises, and cutting-edge AI-native startups. OpenAI recently announced a multi-year partnership with Cerebras , to deploy 750 megawatts of scale, transforming key workloads with ultra high-speed inference.

Thanks to the groundbreaking wafer-scale architecture, Cerebras Inference offers the fastest Generative AI inference solution in the world, over 10 times faster than GPU-based hyperscale cloud inference services. This order of magnitude increase in speed is transforming the user experience of AI applications, unlocking real-time iteration and increasing intelligence via additional agentic computation.

About The Role

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.

Skills and Qualifications

• 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.
