About the role

Role Scope

  • Own security for the cloud and bare-metal control planes customers' training runs depend on: hardening, identity, and workload isolation.
  • Build guardrails as code: policies, scanning, and paved roads that make the secure path the fast path for engineers.
  • Engineer detection and response across cloud infrastructure, from API abuse to compromised credentials to tenant escape.
  • Secure the multi-tenant boundary where customer workloads, some of the most targeted in AI, share infrastructure.

Requirements

  • Secured production cloud or bare-metal infrastructure hands-on, not just audited it.
  • Shipped security tooling engineers actually adopted.
  • Found and fixed real isolation or privilege-escalation issues.
  • Write production-quality code and treat policies as software.
  • Run incident response on infrastructure you helped build.

Nice-to-Haves

  • Kubernetes and container security.
  • Hardware root of trust and measured boot.
  • eBPF-based detection.
  • GPU and HPC environments.
