• Engage with clients, developers, and project teams through regular meetings to manage design progression and risks.
• Support delivery quality by collaborating with the QA team and overseeing contractor compliance during commissioning and handover.
• Mentor Graduate Engineers and contribute to their technical development.
• Participate in an accelerated training programme to support your growth within the sector.
