Job description

What you'll work on

• Build and maintain cloud infrastructure and deployment systems.

• Strengthen security through appropriate identity management, access controls, and secrets handling.

• Stand up alerting, paging, and an on-call rotation the whole team shares, plus the HIPAA and SOC 2 evidence that good infrastructure produces on its own.

• Keep Terraform, CI, and the merge queue fast and safe as the volume of human- and agent-written code grows.

• Document platform patterns and establish reusable engineering standards.

You might be a fit if

• Experience running production systems on AWS, with Terraform and incidents you have owned through to the postmortem.

• Deep PostgreSQL: row-level security, query plans, migrations on live data, and backups you have restored.

• You have built authentication, access control, or audit systems and know where they fail open.

• You create solutions to problems so that other engineers can focus on their work, and you know when to say no to a request that will create more work for the team.

Bonus points

• Experience with k8s, ECS, or other container orchestration systems.

• HIPAA, SOC 2, or HITRUST experience.

• Multi-region or disaster-recovery design for a stateful system.
