Principal Electrical Engineer

Job Description

Principal Electrical Engineer – Data Centres

Up to £75,000 + Benefits

Central London - Flexible Hybrid

An established UK engineering consultancy, independent for over 70 years, is expanding its specialist Data Centre team and is seeking a Principal Electrical Engineer with strong technical design experience. This is an opportunity to join a respected, people-centric business with an average staff tenure of 12 years, a genuine open-door culture, and a commitment to continuous progression without rigid promotion cycles.

Why Join? The same reason people stay!

A genuinely supportive culture

  • No annual reviews or fixed pay-rise cycles — promotions and salary increases happen as soon as they’re earned.
  • “No stupid questions” philosophy — learning is encouraged and supported.
  • Highly selective hiring focused on technical excellence, ensuring you work alongside capable, high-quality engineers.
  • Flexible hybrid working: 2 days in the office (Tue/Thu typically; 3 days initially for onboarding and collaboration).
  • Long-standing leadership that trusts its engineers and provides autonomy.

Strong Benefits Package

  • 25 days holiday + Christmas shutdown (rising to 28 after 6 years)
  • Contributory private healthcare
  • Standard pension
  • EAP including financial & legal support
  • Annual wellbeing day: a full team day out (walks, tours, social events)
  • Chartered Engineer mentorship available (including from a recognised CIBSE Data Centre leader)

About the Data Centre Team

The London-based Data Centre group consists of a core team of five permanent engineers, supported by contractors when needed. The team is led by senior Electrical and Mechanical leads, with a strategic plan to continue growing a central London hub before expanding expertise across other UK offices.

The practice has made a deliberate and successful push into the data centre sector over the last two years, securing work with major global operators (hyperscalers and colocation providers). While most work is UK-based, they are now being asked to support clients on European projects.

Project & Technical Exposure

You will work on both design and technical advisory projects, including:

  • Strategic asset replacement programmes
  • New build data centres up to 100MW
  • Reviewing and upgrading live MEP systems in operational facilities
  • Compliance monitoring
  • Detailed electrical design, specifications and scopes of work
  • Protection studies

This role is hands-on and design-focused — not a project management position (although PM skills can be developed).

What They’re Looking For

  • Senior or Principal-level Electrical Engineer with strong data centre design experience
  • Solid understanding of critical electrical infrastructure and MEP integration
  • Capable of delivering high-quality technical work and contributing to client-facing advisory tasks
  • Someone who values autonomy, collaboration, and technical excellence
  • UK-based, able to attend the London office twice weekly

The consultancy does not use salary bandings and pays based on technical capability — up to ~£70k is realistic for a strong Principal.

If you’re an electrically biased Data Centre specialist looking for a technically engaging role within a supportive, low-ego engineering environment, this position offers long-term growth, high-profile project exposure, and the chance to help shape a growing specialist team.
