Principal HV Cable Design Engineer

UK Energy Infrastructure | Hybrid | Leadership Role

Let's not overcomplicate it.

If you can design high-voltage cable systems properly - and lead others to do the same - this will interest you.

We're hiring a Principal HV Cable Design Engineer to take technical ownership across major grid and renewable infrastructure projects.

Not a back-room checker.

A leader.

The Role

You are the technical authority on HV cable design.

Lead design of 33kV-400kV cable systems
Develop routing, thermal calculations, bonding designs and jointing philosophies
Oversee cable ratings and ampacity studies
Review and sign off detailed engineering outputs
Interface with civils, substation, and protection teams
Provide technical guidance to junior and senior engineersYou'll influence design standards, not just follow them.

The Work

Major energy infrastructure.

Grid reinforcement
Renewable energy connections
Onshore HV export cable systems
Large-scale substation interfacesThese are nationally significant projects. High scrutiny. High standards.

What We're Looking For

You've already earned your stripes.

Proven experience in HV cable design (132kV+ preferred)
Deep understanding of cable systems (XLPE, bonding, sheath calculations)
Strong knowledge of UK utility standards
Experience leading design reviews
Commercial awareness - you understand buildability and cost impactYou don't guess.

You calculate.

You lead.

What You Get

Senior technical ownership
Influence across multiple major projects
Competitive salary & package
Hybrid flexibility
Clear path to engineering leadershipThis isn't a stepping stone role.

It's a platform.

Why This Role Matters

The UK grid is expanding fast.

Cable infrastructure is at the centre of it.

If you want to design systems that move gigawatts - not kilowatts - and lead at principal level, this is your move.
