Job Description

START HERE. GROW HERE.

“Are you ready to join a team of talented engineers to power the future, shape the grid and lead with impact?”
We are seeking a Principal Cables Engineer to join our expanding Transmission & Distribution (T&D) team within AECOM. This is a senior leadership role within the business, with responsibility for driving technical excellence, leading complex projects, and supporting strategic client engagement across a broad portfolio of high-voltage infrastructure schemes.
As a Principal Engineer, you will play a critical role in the planning, design, and delivery of cable systems across multiple voltage levels, spanning both onshore and offshore environments, including HVAC and HVDC applications. Our clients include Transmission System Operators, Distribution Network Operators, private developers, and international energy majors across the UK and globally.
You will lead multidisciplinary project teams, act as a trusted advisor to clients, and contribute to developing our technical standards, innovation strategy, and digital delivery approach within the cable engineering space.
This is a fantastic opportunity to be at the forefront of energy transition, delivering world-class solutions for projects that are shaping the grid of tomorrow.

READY TO PUSH THE LIMITS OF WHAT’S POSSIBLE?

Here’s what we’re looking for:

The successful engineer will have/be:

• Demonstrated experience as a technical leader in HV/EHV cable system design across onshore and offshore projects, AC and DC.
• Proven track record in design, specification, and installation of complex cable systems including subsea, tunnel, urban, and constrained environments.
• In-depth understanding of international and UK-specific standards, particularly National Grid TPs, IEC, and CIGRÉ guidelines.
• Experience working in regulated, quality-assured environments—preferably with National Grid, SSE, EirGrid, or equivalent TSO/DNOs.
• Strong ability to coordinate multidisciplinary engineering teams and engage with senior stakeholders across the project lifecycle.
• Excellent communication, client-facing, and team leadership skills.
• Commitment to fostering innovation, digital delivery, and sustainability in design.

DESIRABLE CERTIFICATIONS & QUALIFICATIONS

• Degree-qualified in Electrical Engineering or related field; MSc/MEng advantageous.
• Chartered Engineer (CEng) status or working towards.
• National Grid CDAE certification or similar.
• Experience with cable system software (e.g., CYMCAP, WinCable) and advanced analysis tools.
• Offshore project delivery certifications (e.g., GWO/BOSIET) beneficial but not essential.
  You will also be self-motivated with an ability to work both autonomously where required, with a strong sense of commitment, a willingness to learn and a desire to work in a dynamic deadline driven team environment.
  At AECOM, we believe in creating a better world through innovative and sustainable solutions. If you share our vision and are ready to make a difference in the energy industry, we want to hear from you.
  Additional Information

• Lead the technical delivery of large-scale HV/EHV cable system projects from concept to completion, ensuring quality, safety, and innovation throughout the lifecycle.
• Develop and oversee HVAC and HVDC cable system designs, including routing, burial risk assessments, thermal, electromagnetic, and mechanical performance modelling.
• Provide expert-level input into cable system ratings, installation methodologies, jointing arrangements, cleating design, and system integration in challenging environments (e.g., subsea, tunnel, urban).
• Guide and validate complex calculations including ampacity, short circuit forces, EMC, induced voltages, and thermomechanical forces to meet compliance with National Grid TPs, IEC, and CIGRÉ standards.
• Lead client and stakeholder engagement, providing technical assurance, strategic direction, and value-engineered solutions on high-profile infrastructure programmes.
• Manage coordination between disciplines, including civil, structural, OHL, substation, and marine engineering inputs, to ensure cohesive and integrated design solutions.
• Drive project execution, managing technical risks, interfaces, and quality reviews while supporting procurement, construction, and commissioning phases.
• Conduct 3rd-party inspections, FAT/SAT witnessing, and vendor oversight for cable and ancillary equipment.
• Champion mentorship, knowledge-sharing, and technical development within the wider team, supporting capability growth in cable systems engineering.
• Support business development activities, including proposals, bid reviews, and client presentations.
