Cerebras Systems

Security Engineer

• Define and own the architectural roadmap for Cerebras's enterprise, data center, and cloud network estate.
• Co-author secure design and lifecycle management of high-performance data center networking — including spine/leaf, RDMA, and high-bandwidth fabrics supporting wafer-scale compute.
• Build and maintain an AI-agent based analysis and review framework for network changes as well as self-improvement driven by observed network patterns and use cases.
• Partner with Network Security to deliver segmented, zero-trust-aligned network designs across data center and corporate environments.
• Set standards for resiliency, observability, and capacity planning across the global network
• Mentor engineers across regions (US, Canada, Bangalore, and beyond), and serve as the senior technical voice on cross-functional network initiatives.
• Stay ahead of emerging networking patterns relevant to AI infrastructure and translate them into actionable architecture decisions.

Principal Network Security Architect

• Define security architecture and build controls for AI platforms, training and inference workflows, model-serving systems, customer workloads, developer workflows, and agentic
• Develop reusable AI and agent security patterns for identity, authorization, delegated authority, scoped tool access, MCPs, connectors, secrets, approvals, isolation, auditability, and
• Design runtime controls that constrain execution, access, data exposure, model and tool interaction, and blast radius.
• Build security capabilities as code using infrastructure as code, configuration as code, policy as code, GitOps, CI/CD, and automated validation.
• Define secure development patterns for AI systems, agents, prompts, tools, models, policies, evaluations, releases, and rollback.
• Automate security reviews, policy checks, evidence collection, control validation, and remediation
• Instrument AI, agent, and platform activity with telemetry, traceability, policy decisions, audit logs, anomaly signals, and response workflows.
• Lead hands-on security reviews and influence product, platform, infrastructure, and security architecture through practical design changes and reusable controls.

Principal AI Security Engineer

• Design and operate firewall, segmentation, and zero-trust controls across data center, corporate, and cloud (AWS) networks.
• Build and maintain network security infrastructure as code — including firewall rules, policy automation, and CI/CD-driven deployment.
• Lead network lifecycle management: design review, configuration baselines, change automation, and ongoing rule hygiene.
• Build detection capabilities for network-based attacker behaviors and partner with the Detection & Response team on response playbooks.
• Implement and operate network access controls including ZTNA, VPN, and remote access patterns.
• Drive periodic firewall rule reviews, segmentation audits, and remediation campaigns to reduce risk and complexity.
• Document network security architecture, controls, and operating procedures in clear runbooks.

Network Security Engineer

• 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.
