• Provide hands on technical leadership across complex, high impact engineering challenges
• Lead the development and adoption of engineering standards, patterns, guardrails and reusable approaches
• Lead the evolution of AI augmented engineering, identifying, proving and scaling approaches that improve how we design, build, test and deliver software
• Bring systems thinking across frontend, backend, mobile and integration engineering
• Influence software strategy, technical direction and significant engineering decisions across teams and platforms
• Provide enterprise level technical design leadership and proportionate assurance for significant or high risk work
• Guide detailed technical decisions, balancing quality, cost, security, resilience and long term sustainability
