Senior Civil Engineer – Highways & Drainage

Senior Civil Engineer – Highways & Drainage Shape the Future of Infrastructure Delivery

Tetra Tech is seeking an experienced and motivated Senior Engineer to join our Highways and Civils team, based in either Newark or Birmingham, with hybrid working available. This role offers an excellent opportunity for a technically strong highways and drainage engineer who enjoys problem solving, working collaboratively, and contributing to the delivery of complex infrastructure projects across residential, commercial, industrial, and strategic development sectors.

As a Senior Engineer, you will contribute to the technical delivery of highways and drainage projects across a broad range of infrastructure schemes. You will be involved in all stages of design, from concept layouts and feasibility studies through to detailed design and technical approvals. The role requires strong analytical skills, practical engineering judgement, and the ability to deliver high‑quality design outputs under the guidance of senior technical leaders.

You will work closely with multidisciplinary teams, support the preparation of reports and design documentation, and help maintain a consistent level of technical excellence. Alongside your design responsibilities, you will mentor junior engineers and technicians, helping the wider team build capability and confidence. You will also engage with clients and design partners, supporting the coordination and communication necessary to deliver successful project outcomes.

You will play an active role in the delivery of highways and drainage designs for development‑led infrastructure projects, including estate roads, junction improvements, access strategies, earthworks, and drainage systems. You will support technical approval processes (S104, S278, and S38) with Water Authorities, Local and National Highways Authorities, preparing submissions, responding to comments, and contributing to the approvals strategy.

Your role will involve producing and reviewing technical drawings, models, assessments, and calculations, while supporting colleagues across Newark, Birmingham, London, and the wider Tetra Tech RPS infrastructure team. You will be trusted to manage your own tasks independently, contributing to smaller projects and supporting the delivery of larger, more complex commissions. Your work will help ensure that technical quality, client expectations, and programme requirements are consistently achieved.
