What You'll Do:

CoreWeave is the AI hyperscaler, operating infrastructure at a scale and level of complexity required to support the most demanding AI workloads in the world. In this role, you will lead and scale CoreWeave's Platform Security engineering function, owning how security is designed into the Kubernetes-based platform and public cloud environments. This is a hands-on engineering leadership role focused on building and operating security controls, not writing policy. You will define strategy and execution for cloud security posture, workload isolation, platform guardrails, image integrity, and multi-cloud security across CoreWeave's own Kubernetes infrastructure and third-party cloud platforms including AWS, GCP, and Azure. You will lead and grow a team of platform security engineers and partner closely with Infrastructure, Platform Engineering, SRE, and other security teams to ensure platform security capabilities scale alongside the business. This role reports to the Senior Director of Security Foundations.

About The Role:

CoreWeave delivers GPU-accelerated infrastructure purpose-built to support the most demanding AI and machine learning workloads in the world. Our platform is designed for extreme performance, scale, and reliability, supporting frontier AI development across a rapidly expanding global footprint.

As CoreWeave continues to scale, securing the platform layer that underpins customer workloads and internal services is a critical foundation for the business. Platform Security at CoreWeave is an engineering discipline focused on building and operating systems that enforce security at the infrastructure layer across both our Kubernetes-based platform and third-party public cloud environments.

The team owns the technical design, implementation, and operation of cloud security posture management, workload isolation, platform-level guardrails, and image integrity controls. This role is responsible for running, evolving, and operating CoreWeave's Platform Security engineering program and team in close partnership with Infrastructure, Platform Engineering, SRE, and other security stakeholders.

Core job duties include, but are not limited to:

• Own the strategy, roadmap, and execution of CoreWeave's Platform Security engineering program across Kubernetes and multi-cloud environments.
• Lead and develop a team of platform security engineers through mentorship, technical direction, and performance management.
• Design, build, and operate security controls for CoreWeave's Kubernetes-based platform, including workload isolation, admission control, runtime policy enforcement, and tenant boundary integrity.
• Drive the security posture of CoreWeave's third-party public cloud environments (AWS, GCP, Azure), including account governance, IAM hygiene, configuration baselines, and automated guardrails.
• Own and mature cloud security posture management (CSPM) capabilities, ensuring continuous visibility and automated remediation across all cloud environments.
• Build and operate image integrity and supply chain security controls, including image signing, provenance verification, and base image governance.
• Partner closely with Infrastructure and Platform Engineering to embed security into the Kubernetes control plane, admission pipelines, and deployment workflows.
• Collaborate with Security Operations on detection, investigation, and response for platform and cloud security incidents.
• Define engineering standards, guardrails, and metrics that scale platform security capabilities with the organization.
• Act as a senior escalation point for platform and cloud security risks, incidents, and complex cross-functional issues.

Who You Are:

• You have 5 to 10 or more years of experience in platform security, cloud security, infrastructure security, or adjacent security engineering domains.
• You have 3 to 5 or more years of experience leading or managing engineers, either as a people manager or technical leader with people responsibility.
• You bring strong hands-on depth in Kubernetes security, including admission control, RBAC, network policy, runtime security, and workload isolation patterns.
• You have experience designing and operating security controls across multiple public cloud platforms (AWS, GCP, Azure), including IAM, account governance, and configuration management.
• You prefer building and operating systems over writing policy documents.
• You are comfortable owning ambiguous problem spaces and turning them into clear technical plans and outcomes.
• You communicate clearly and partner effectively across Infrastructure, Platform Engineering, SRE, and Security.

Preferred:

• Experience with CSPM platforms such as Wiz.
• Experience with container image signing and supply chain security tooling (Sigstore, Cosign, Chainguard).
• Experience with infrastructure-as-code tooling, especially Terraform.
• Proficiency with automation or programming languages such as Go or Python.
• Experience with admission control frameworks such as OPA Gatekeeper or Kyverno.
• Experience securing multi-tenant Kubernetes environments at scale.
• Familiarity with security frameworks such as NIST, ISO, or SOC2 in the context of infrastructure and platform security.
