• Manage engineering priorities, sprint planning, testing, documentation and releases

• Establish strong engineering standards across code quality, testing and deployment

• Lead and support engineers, contractors and external development partners

• Help evolve Agile X towards data visualisation, predictive analytics, automation and AI-assisted operational decision-making
