• Develop tools and automation that improve reliability, performance, and developer experience — using languages like Python, PHP, or Go. • Design and implement infrastructure for scalability and resilience across AWS, Fly.io, and related cloud services. • Build developer-facing systems: internal APIs, build pipelines, CI/CD automation, observability tooling, and service orchestration. • Instrument and monitor applications to detect customer-facing symptoms first, surfacing root causes through dashboards and metrics. • Partner with developers to build services that are secure, observable, and easy to deploy. • Define Service Level Objectives (SLOs) and metrics that balance uptime and velocity. • Participate in on-call rotations, incident response, and postmortems — turning lessons learned into permanent fixes. • Promote security best practices across builds, deployments, and code reviews. • Collaborate cross-functionally to guide engineering practices and improve the entire software delivery lifecycle.
