## Description

Your time will be split roughly evenly between two areas.

 * On the reliability side, you'll be a US-based point of contact for the platform: investigating issues as they come up, improving monitoring, alerting, and dashboards, and turning recurring problems into lasting fixes.
 * On the infrastructure and developer experience side, you'll evolve our Terraform-based AWS infrastructure along with the CI/CD pipelines, environments, and tooling our engineers use every day, making it faster and safer to ship as more of our development is done alongside AI agents.
 * You'll work closely with backend, frontend, and DevOps engineers across the US and Europe, partner with Medtronic security and cloud teams on reviews and compliance, and contribute to architecture decisions around scalability, cost, and security.
