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. T

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- You have experience designing and operating security controls across multiple public cloud platforms (AWS, GCP, Azure), including IAM, account governance, and configuration management
You communicate clearly and partner effectively across Infrastructure, Platform Engineering, SRE, and Security
You are comfortable owning ambiguous problem spaces and turning them into clear technical plans and outcomes
You have 5 to 10 or more years of experience in platform security, cloud security, infrastructure security, or adjacent security engineering domains
You bring strong hands-on depth in Kubernetes security, including admission control, RBAC, network policy, runtime security, and workload isolation patterns
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 prefer building and operating systems over writing policy documents
Experience with CSPM platforms such as Wiz
Experience with infrastructure-as-code tooling, especially Terraform
Experience with container image signing and supply chain security tooling (Sigstore, Cosign, Chainguard)
Experience with admission control frameworks such as OPA Gatekeeper or Kyverno
Proficiency with automation or programming languages such as Go or Python
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
