  • Git-based workflows (GitHub), branching and code review standards

  • CI/CD automation (e.g., GitHub Actions) for build, test, and deploy

  • Test automation and repeatable validation of changes

• Champion the thoughtful use of AI in the engineering lifecycle (e.g., code assist, test generation, defect analysis) to automate workflows and improve quality and speed.

• Partner with platform, SRE, and security teams to ensure availability, observability, compliance, and operational excellence for production systems.

• Use metrics (lead time, deployment frequency, change-failure rate, escaped defects, availability) to guide decisions and continuously improve how the team works.

• Represent the team in forums with product, business, and leadership stakeholders, clearly communicating status, risks, and trade-offs.
