Job description

Help shape the future of the UK's energy infrastructure.

At Kelvin Power, we're powering the future of the UK's energy infrastructure, and we're looking for an experienced Senior Overhead Line (OHL) Engineer to join our growing engineering team.

As part of the global VINCI Energies Group, Kelvin Power delivers specialist engineering consultancy and design solutions across major electricity transmission and infrastructure projects throughout the UK and Ireland.

With an expanding portfolio of projects and continued investment in our engineering capabilities, this is an exciting opportunity to take a leading role in delivering technically challenging 132kV to 400kV overhead line transmission projects, including schemes for National Grid Electricity Transmission (NGET).

You'll play a key role in leading technical design, supporting project delivery and mentoring the next generation of engineers, while contributing to the continued growth and success of Kelvin Power.

The Role

As our Senior OHL Engineer, you'll take technical ownership of overhead line design projects, working closely with multidisciplinary engineering teams, clients and construction partners.

From initial feasibility through to detailed design and construction support, you'll help deliver innovative, practical and cost-effective engineering solutions that support the UK's evolving electricity network.

Key Responsibilities

Technical Leadership & Design

• Lead the design and delivery of 132kV, 275kV and 400kV overhead line transmission projects, ensuring technical excellence and timely delivery.
• Manage OHL design activities from feasibility and FEED through to detailed design, construction support and final handover.
• Deliver designs for new-build, refurbishment, reconductoring and point-of-connection projects.
• Undertake conductor system design and line modelling using PLS-CADD, including sag and tension calculations, stringing charts, clearance diagrams and line schedules.
• Carry out structural analysis, modelling and strengthening of steel lattice towers using PLS-Tower, including tower modifications, extensions and terminal arrangements.
• Assess existing tower foundations and develop suitable upgrade and strengthening solutions.
• Produce and review technical drawings, insulator arrangements, line fittings, temporary diversion designs and earthwire/OPGW solutions.

Project Delivery & Collaboration

• Ensure all engineering designs comply with NGET Technical Specifications, BS EN 50341 and relevant Eurocodes.
• Work collaboratively with our civil, structural, electrical, substation and cabling teams to deliver fully integrated engineering solutions.
• Review and approve technical deliverables, ensuring compliance with project requirements, quality standards and best practice.
• Liaise with clients, contractors and construction teams throughout the project lifecycle.
• Attend site visits, line surveys and client meetings across the UK.
• Support the management of a portfolio of projects, ensuring successful delivery against agreed budgets, programmes and commercial objectives.

People Development & Continuous Improvement

• Provide technical guidance, mentoring and support to OHL design engineers and technicians.
• Share expertise and encourage technical development across the wider engineering team.
• Contribute to the improvement of engineering processes, design standards and quality assurance.
• Support tender submissions, technical proposals and project estimates.
