The Role

We’re looking for an experienced and client‑focused Principal Engineer with electrical design experience to join our data centre team.

You will have excellent electrical design and consulting experience, ideally from a highly technical background.

As part of the role, you’ll be engaging directly with clients, shaping technical strategies, as well as reviewing and developing designs for our projects. You’ll be trusted to take ownership of your work while being supported by a team of experienced engineers.

As a Principal, you’ll also support the development of junior engineers, as well as contribute to project planning and fee proposals. In a leading role, you’ll help bring your technical expertise to the market and shape the direction of our growing team.

Responsibilities

• Produce electrical designs, including schematic diagrams, layouts, and technical calculations.
• Prepare technical specifications, calculations, schedules, project reports, and supporting documentation.
• Conduct site inspections and surveys to inform and validate design development.
• Develop detailed and coordinated design solutions in collaboration with multi‑disciplinary teams.
• Contribute to internal and external project meetings, providing electrical expertise and updates.
• Assist with fee proposals and business development activities as required.
• Collaborate with colleagues across regional and international offices on project delivery.

The Skills

You’ll have gained experience in a consulting engineering role and now looking to take this into a new challenge with greater responsibility and impact. We value engineers who bring initiative, problem‑solving, and a collaborative mindset to their work.

You don’t need previous data centre experience. Our DC101 programme has been designed to provide in-depth technical training alongside your projects to ensure new joiners can succeed in the industry. This programme has led to multiple award wins and nominations for talent development across the data centre sector.
