Responsibilities

  • Design and implement secure, multi-tenant infrastructure that isolates customer data while enabling efficient AI model serving across our platform
  • Build "golden paths" for security including service templates, libraries, terraform policies, and automation, so new services are secure and production-ready by default
  • Own infrastructure-as-code (Terraform) and GitOps best practices, including reusable modules and policy-as-code
  • Expand and help operate the platforms behind alerting detection, secrets management, IAM, and automated remediation, integrating them cleanly into CI/CD and developer workflows
  • Partner with Security, Infrastructure, and product engineering teams to translate enterprise and compliance requirements (SOC 2, ISO 27001, GDPR) into reliable, automated technical controls
  • Participate in security on-call and continuously raise the bar on operability, runbooks, and incident learnings

Qualifications

  • 5+ years building and operating production infrastructure, with meaningful exposure to security or a strong interest in moving deeper into security problems
  • Deep knowledge of Google Cloud Platform and/or AWS, including compute, networking, IAM, and security services
  • Proficiency with infrastructure-as-code (Terraform, Ansible, or similar) and a track record of building developer-facing tooling and automation
  • Strong coding ability in at least one systems language (eg. Python, Go, TypeScript) and comfort building paved-path tooling teams actually adopt
  • Experience applying AI-assisted tooling (Cursor, Claude Code, and similar) to make engineers dramatically more effective
  • Experience with secure container deployment, service mesh, and Kubernetes security best practices
  • Observability and incident-response tooling experience (instrumentation, alerting, dashboards), with a bias toward eliminating toil
  • Clear written communication and the ability to turn ambiguous requirements into simple, reliable designs
