• Identify and resolve technical issues across software, hardware, and system interfaces
• Support value engineering efforts to optimise cost and performance of solutions
• Contribute to the development and improvement of engineering standards, tools, and processes
• Support Business Development teams with technical input for proposals and bids where required
• Coordinate with cross-functional teams to align scope, schedule, and deliverables.
• Communicate clearly and proactively with internal teams, customers, and partners.
• Act as a technical interface between Engineering, Integration, and Operations teams.
• Support project leadership in identifying risks, resolving issues, and maintaining delivery alignment.
• Identify and escalate technical risks, constraints, or scope changes early.
