• Buildability & Value Engineering: Review engineering drawings, P&IDs, and models to resolve buildability issues early, driving value engineering solutions suited to active wastewater treatment environments.
• Progress & Deliverable Management: Drive the Design Deliverable Schedule (DDS) to align with site construction milestones, tracking and resolving Technical Queries (TQs) and RFIs.
• Regulatory Compliance & Approvals: Ensure design submissions comply with water authority specifications, WIMES standards, environmental regulations, and CDM 2015.
• On-Site Technical Support: Spend 50% of your time on-site in Kingston, interfacing directly with Project Managers, Site Engineers, and operations teams to resolve live design interface challenges.

Requirements & Qualifications

• Water Sector Experience: Proven track record as a Design Manager or Design Coordinator delivering water infrastructure or sewage treatment projects (STW, WwTW, or AMP frameworks) in the UK.
• Technical Breadth: Strong working knowledge of wastewater process assets, water infrastructure networks, pipework networks, and MEICA design integration.
