You'll collaborate across multiple departments - including engineering, planning, and commercial - to develop realistic programmes, identify value engineering opportunities, and support pricing strategy at board level. This is a highly visible role within TMS Maritime and offers the opportunity to influence how we win, plan, and deliver projects nationwide.
