  • Contribute to observability across services, helping teams better understand performance, reliability and user impact. 
  • Develop and improve CI/CD pipelines to enable safe, frequent and low-risk delivery of changes. 
  • Collaborate with product, delivery and architecture colleagues to ensure platform services meet user and business needs. 
  • Support live service operations, including incident response, troubleshooting and problem management, with a focus on learning and continuous improvement. 
  • Share knowledge and provide coaching and mentoring to colleagues, contributing to a supportive and inclusive engineering community.
