Influence & Mentoring:

• Act as a trusted technical partner to engineers and managers, shaping design decisions and reducing complexity.
• Provide coaching and feedback to strengthen technical capability and delivery quality.
• Champion emerging technologies to maximise engineer contribution, delivery capability and customer value.

• Strong analytical and problem-solving ability with a passion for simplifying complex systems.
