Security Engineer, Infrastructure Security

Designs and builds security controls for infrastructure including GPU clusters, multi-cloud setups, datacenters, Kubernetes, and networks to protect AI models and data from advanced threats. Requires deep security expertise, cloud platform knowledge, and proactive problem-solving across on-prem and cloud environments.

About the job

Responsibilities

  • Design and build security controls across diverse layers (e.g., physical hardware, firmware/BMC, OS, Kubernetes, networks, and CI/CD) to defend against sophisticated adversaries and insider threats.
  • Collaborate with engineering and security teams to drive deployment of security enhancements and control changes across broad-scale infrastructure.
  • Tackle high-impact projects such as checkpoint encryption, network isolation, secret management, and machine identity, while continuously raising the security bar for emerging AI workloads.
  • Take a generalist approach to building security controls, balancing a mix of security expertise and broad technical skillsets to adapt to evolving challenges.

Requirements

  • Deep understanding of security principles, best practices, and common vulnerabilities.
  • Proactive mindset, with the ability to identify and address security gaps or inefficiencies through automation and tooling.
  • Track record of delivering scalable solutions and driving impactful changes across infrastructure in real-world projects.
  • Expertise in the security of cloud platforms (e.g., Amazon AWS, Microsoft Azure), especially securing multi-cloud networks and infrastructure, and designing cloud agnostic systems.
  • Experience securing on-prem deployments and datacenters from construction to multi-tenant use.
  • Familiarity with container security, orchestration security, and authentication/authorization.
  • Strong analytical and problem-solving skills, with an ability to think critically and objectively assess security risks.
  • Excellent communication skills, with the ability to convey complex security concepts to technical and non-technical stakeholders.
  • Excitement about collaborating with cross-functional teams to build secure, reliable systems that scale globally.
