We are hiring a founding platform security engineer to build and operate the security infrastructure behind an enterprise AI platform. This hands-on role will shape the infrastructure security program and help engineering teams ship secure, reliable services by default.

• Design and implement secure, multi-tenant infrastructure that protects customer data and supports efficient AI model serving.

• Build secure service templates, libraries, Terraform policies, and automation that make services production-ready by default.

• Own infrastructure-as-code and GitOps practices, including reusable modules and policy-as-code.

• Develop and operate alerting, detection, secrets management, IAM, and automated remediation capabilities, integrating them with CI/CD and developer workflows.

• Partner with security, infrastructure, and product engineering teams to turn compliance requirements into automated technical controls.

• Participate in security on-call and improve observability, runbooks, and incident learnings.

On-site in San Francisco, California.

• At least 4 years of infrastructure or platform engineering experience, with meaningful security exposure or a strong interest in security engineering.

• Production experience with cloud infrastructure on GCP and/or AWS, including networking, IAM, compute, and security services.

• Hands-on Terraform and Kubernetes expertise, plus experience with GitOps, secure container deployment, or service mesh.

• Strong coding skills in Python, Go, TypeScript, or a similar language, and experience building developer-facing tools and automation.

• Experience with observability, alerting, and incident response.

• Ability to apply AI-assisted development tools to improve engineering workflows.

• Experience translating enterprise security and compliance needs, such as SOC 2, ISO 27001, and GDPR, into practical controls is valuable.

• Experience building infrastructure or security capabilities in a startup or high-growth environment is a plus.
