Runway is hiring an Infrastructure Security Engineer to secure the platform our models are trained and served on. The role covers Kubernetes platform security, cloud identity and access, software supply chain, tenant isolation in the serving layer and the research infrastructure behind our models.
Securing a company that trains and serves frontier video models is a different problem from securing a typical SaaS product. The environment includes research compute, large training datasets, a fast-moving build pipeline, and engineers who work inside AI-assisted tooling every day. Each of those changes what an attack looks like and what the platform has to enforce to stop it.
This is a hands-on engineering role on the Security team. You'll write policy, tooling and infrastructure code, work in the platform team's repositories, and ship controls that hold up in production.
Design and ship security controls in our Kubernetes ecosystem: admission policy, RBAC, workload identity, network policy and runtime hardening across every cluster we run
Harden the software supply chain from dependency intake through build and deploy, including package firewalling, artifact signing and provenance, and admission controls that block what doesn't pass
Own cloud IAM and identity architecture: least-privilege roles, short-lived credentials and workload federation
Secure research infrastructure and training pipelines, including access to model weights and datasets, without slowing down the people using them
Threat model new platform components before they ship and turn the findings into concrete requirements the owning team can act on
Build guardrails for AI agents and developer tooling operating inside our infrastructure
Write infrastructure as code and policy as code, and treat security configuration with the same review and rollout discipline as any other change
Give the incident response team what they need when infrastructure is involved: fast answers about how a system works and what to shut off
