Drive Operational Excellence

  • Build secure, resilient and observable platforms.
  • Implement SLOs, operational practices and recovery capabilities.
  • Diagnose incidents and performance issues and drive continuous improvement.
  • Embed security and compliance into delivery pipelines and platform services.

Contribute to Engineering Impact

  • Partner with product, engineering and security teams.
  • Identify recurring team needs and convert them into reusable platform capabilities.
  • Influence technical outcomes across your team and adjacent engineering teams. 
What do I need?
