Design and coordinate utilities, underground services, ducts and road interfaces.

Coordinate technical information across multidisciplinary project teams.

Produce designs using Civil 3D and MicroDrainage or InfoDrainage.

Take responsibility for defined work packages, ensuring technical quality and timely delivery.

Essential Skills & Experience

Strong technical background in civil infrastructure design beyond drainage alone.

Experience in drainage, earthworks, pavement design, external works and levels.

Proficiency in Civil 3D and MicroDrainage or InfoDrainage.

Understanding of underground utilities, ducting and 3D services coordination.

Ability to manage and deliver design packages independently.

Experience coordinating with other engineering disciplines.

Relevant Civil Engineering degree or qualification.

Desirable Experience

Previous involvement in Power, Energy, Substation or Utilities infrastructure projects.

Experience working on complex multidisciplinary engineering schemes.

Chartered Engineer (CEng) or Incorporated Engineer (IEng) status with ICE.

Experience within Nuclear, Defence or other regulated sectors.

Contract Details & Benefits

Contract opportunity supporting an established engineering consultancy.

Inside IR35 assignment.

Hybrid working from London, Warwick or Manchester.

Exposure to major Power and Infrastructure projects.

Potential opportunities to contribute to Nuclear and Defence projects, subject to security clearance.

Collaborative multidisciplinary engineering environment.

Security Clearance Requirements

Candidates must be eligible to obtain and maintain the appropriate security clearance or assurance level.

Basic clearance or assurance will be required for the initial Power sector work. Security Check (SC) clearance will be required for any Nuclear or Defence projects.

Additional nationality or residency requirements may apply depending on the project.
