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.
