• Work with Infrastructure as Code (Terraform) as part of the delivery pipeline.
• Troubleshoot build, deployment and pipeline issues, identifying root causes and putting lasting fixes in place.
• Improve pipeline reliability, speed and visibility through monitoring, logging and continuous improvement.
• Work closely with developers, engineering leads and customer stakeholders to improve delivery practices and promote DevOps ways of working.
• Produce clear documentation and share knowledge with other engineers and teams.
• GitHub Enterprise administration, or experience rolling GitHub out across multiple teams.
