Lead Engineer / Principal Engineer / Design Manager / Senior Design Manager- Civil & Structures

Overview

We are seeking experienced Civil, Structures, and Pipeline engineers with a strong background in the Water and Wastewater sector to help deliver major infrastructure and non-infrastructure projects, as well as utility frameworks. The role spans the full project lifecycle, from feasibility and concept design through detailed design and construction support. International experience is required, with primarily UK / Ireland experience preferred.

You will collaborate closely with clients, contractors, the Lead office outside India, and multidisciplinary engineering teams. You will take responsibility for technical delivery, coordinate complex interfaces, and deliver high-quality engineering solutions. The position also offers opportunities to lead projects and frameworks, mentor junior staff, and contribute to major UK water infrastructure programmes.

You will be a self-motivated and accountable professional with strong analytical abilities, stakeholder management skills, client-facing experience, and excellent communication. Chartered Engineer status, or a commitment to achieving Chartership, is advantageous.

Your Role

As a Civil/Structural Design/Pipeline Engineer, you will lead the design, review, and delivery of water, wastewater, and utility infrastructure projects. This includes water transmission pipelines, trunk mains, gravity sewers, pumping stations, reservoirs, detention tanks, storm overflow chambers, outfalls, headworks, treatment units, manholes, and associated civil and structural assets. You will produce practical, safe, and buildable engineering solutions by undertaking and reviewing civil and structural designs, calculations, specifications, and drawings in line with relevant standards and project requirements. You will manage multidisciplinary coordination across Civil, Structural, Mechanical, Process, Electrical, ICA, Geotechnical, and BIM teams, support projects through all design stages from concept to construction, and ensure designs meet programme, budget, safety, sustainability, and constructability objectives.

Key Responsibilities

• Lead the design, review, and delivery of water, wastewater, stormwater, and utility infrastructure projects.
• Design and review civil infrastructure including pipelines, pumping stations, reservoirs, detention tanks, drainage systems, manholes, outfalls, storm overflow chambers, and headworks.
• Design and review reinforced concrete and steel structures, including liquid-retaining structures, treatment units, retaining walls, thrust blocks, valve chambers, and associated facilities.
• Prepare and review engineering calculations, design reports, specifications, General Arrangement drawings, detailed design drawings, and Bar Bending Schedules (BBS).
• Develop detailed pipework designs, including pipe material selection, fittings, bedding, thrust restraint systems, utility crossings, and flow control structures.
• Undertake site layout design, drainage studies, earthworks, bulk earthworks, and grading design.
• Perform route selection studies, utility coordination, constructability assessments, utility diversion designs, and easement evaluations.
• Support hydraulic modelling, network planning, capacity assessments, flood risk studies, resilience improvements, and infrastructure investment planning.
• Utilize engineering software including Autodesk Robot, Revit, Civil 3D, Navisworks, ArcGIS Pro, ArcGIS Online, QGIS, and related design and analysis tools.
• Coordinate multidisciplinary design interfaces and undertake 3D BIM coordination, clash detection, and Common Data Environment (CDE)-based project delivery.
• Provide construction-phase support through site queries, Technical Queries (TQs), RFIs, and design issue resolution.
• Review and check calculations, drawings, and deliverables prepared by other engineers while mentoring and supporting junior team members.
• Manage design scope, Basis of Design, project schedules, budgets, and risk assessments while ensuring compliance with relevant engineering standards, health and safety regulations, and CDM requirements.
