  • Advance our supply chain security posture — investments in SAST and artifact attestation with meaningful work to implement them
  • Troubleshoot hard infrastructure problems across network, application, and system layers — complex problems requiring cross-layer analysis

  • Configuration management experience with Ansible and/or Terraform
