Security Engineering Manager, Platform Security

About the role

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.

Responsibilities

• 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.

Requirements

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.

Qualifications

• 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.

Skills

You enjoy building and scaling security engineering systems, not policy programs. You care deeply about developing people and creating healthy, high-performing teams. You are energized by enabling a fast-growing business to move quickly and securely. You are comfortable operating in ambiguity and making thoughtful tradeoffs. You believe platform security should reduce risk while empowering engineers to ship with confidence.
