We are currently recruiting for an experienced Mechanical Engineer to join a major Kier-led water infrastructure programme, working across the Thames Valley and surrounding areas.

With significant investment being made across the UK water sector, this is an excellent opportunity for a Mechanical Engineer to become involved in major water and wastewater infrastructure projects, including treatment works upgrades, process improvements, pumping systems, mechanical installations and commissioning.

📍 Central location: Thames Valley / Oxfordshire
📍 Projects across: Oxford, Swindon, Reading & Harpenden
💼 Permanent or Contract: Both options available

The successful candidate will have the opportunity to work on a portfolio of significant Thames Water AMP8 projects, potentially including major sewage treatment works upgrades and wider water infrastructure schemes across the region.
