What you will do

• Anticipate infrastructure needs from the engineering roadmap and work with the founders on platform direction.
• Improve CI, deployment, and environment spin-up to reduce developer waiting time.
• Run monitoring, logging, alerting, and incident response; lead major infrastructure builds and own product security.
• Make build-versus-managed-service decisions and provide tooling that enables engineering, GTM, AI, operations, and compliance teams to work independently.
