Principal Security Engineer, Infrastructure Security

About This Opportunity

We are representing a confidential AI research organization in their search for a Principal Security Engineer specializing in Infrastructure Security. Our client is at the forefront of developing advanced AI systems and requires exceptional security leadership to protect their cutting-edge research and production environments.

This is a high-impact role where you'll set technical direction for securing complex infrastructure spanning GPU supercomputing clusters, multi-cloud environments, datacenters, and the critical services powering frontier AI models. You'll own security outcomes for critical infrastructure areas, from bare-metal hardware and firmware through Kubernetes clusters, service meshes, and data storage systems protecting highly sensitive model weights and user data.

Responsibilities

• Own end-to-end security outcomes for one or more critical infrastructure areas, including multi-quarter strategy, roadmap, and delivery
• Design and build security controls across diverse layers including physical hardware, firmware/BMC, operating systems, Kubernetes, networks, and CI/CD pipelines to defend against sophisticated adversaries and insider threats
• Lead cross-functional programs to deploy security enhancements and control changes across broad-scale infrastructure, balancing security guarantees with reliability and velocity
• Take a generalist approach to building security controls, balancing security expertise with broad technical skillsets to adapt to evolving challenges
• Lead and drive threat modeling and design reviews for major infrastructure changes, ensuring strong security foundations and operational excellence
• Mentor and level up engineers across infrastructure security and partner teams, contributing to a strong security culture through guidance, reviews, and technical leadership

What We're Looking For

• Deep understanding of security principles, best practices, and common vulnerabilities, with strong security judgment under ambiguity
• Proactive mindset with ability to identify and address security gaps or inefficiencies through automation and tooling
• Expertise and curiosity about using advanced AI models and agents to effectively solve security challenges
• Track record of leading large, cross-organizational initiatives from concept to rollout, including navigating tradeoffs, driving alignment, and delivering measurable risk reduction
• Deep expertise in security of cloud platforms (Amazon AWS, Microsoft Azure), especially securing multi-cloud networks and infrastructure, and designing cloud-agnostic systems
• Experience securing on-premises deployments and datacenters from construction through multi-tenant use
• Familiarity with container security, orchestration security, and authentication/authorization systems
• Strong analytical and problem-solving skills with ability to think critically and objectively assess security risks
• Excellent communication skills, with ability to convey complex security concepts to executive, technical, and non-technical stakeholders
• Excitement about collaborating with cross-functional teams to build secure, reliable systems that scale globally
