About The Role

We have an exciting opportunity for a Principal / Associate Electrical Engineer to join our Data Centre & Mission Critical (MCDC) team at Hoare Lea.

Data centres are central to the modern economy and the technology that powers them is evolving rapidly. Our Mission Critical team helps clients navigate these changing requirements. At Hoare Lea you'll gain a truly unique experience working across the full spectrum of the data-centre sector - from early-stage site appraisal, masterplanning and feasibility studies through detailed design, live plant upgrades, test-fits, commissioning and operational optimisation. This breadth means you'll work on single-building and campus-scale schemes, hyperscale, colocation and enterprise/research clients, and be exposed to cutting-edge topics such as AI-ready cooling, high-density power architectures and low-carbon integration.

You'll work across complex live plant upgrades, grey and white space in facilities, electrical design, critical engineering, and due-diligence reviews of existing facilities. Projects span mainly in the UK, but also across Ireland and Europe.

You will join a collaborative, knowledgeable and highly engaged team with a positive, supportive and flexible culture. Working alongside the Project Leader, you will engage directly with clients, develop designs and produce reports, specifications and guidance, and support testing and commissioning activities to deliver consistent, high-quality outcomes.

In this key and varied role you will

• Own day-to-day technical delivery of electrical design services for data centre and mission-critical projects.
• Lead development of initial strategic concepts that meet the brief and regulatory requirements.
• Act as a client-facing engineer: attend project meetings, interpret and communicate the brief, and maintain stakeholder relationships.
• Coordinate multidisciplinary inputs (sustainability, acoustics, fire engineering, security, etc.) to deliver integrated building and campus solutions.
• Prepare and review design deliverables, specifications and technical reports, and contribute to proposals, scope development and bid content.
• Provide pragmatic technical input during early-stage site appraisals, masterplanning and test-fit studies.
• Oversee testing, commissioning and handover activities to maintain resilience and uptime.
• Support monitoring of fee expenditure, resource allocation and project delivery alongside the team leader.
• Mentor and develop 'next-gen' professionals, including apprentices and graduates.

About You

To be successful in this role you'll need:

• Proven experience as an Electrical Engineer (or closely related role) delivering Mission Critical and Data Centre projects.
• Experience with modern technical delivery processes and software/tools such as Revit, BIM workflows, Electrical OM, Dialux and Relux.
• Demonstrable client-facing consultancy experience working with clients, contractors and architects on design-led projects.
• Strong technical judgement, self-awareness, a collaborative mindset and an open, generous approach to teamwork.
• Experience mentoring and supporting others to develop knowledge, skills and confidence.

Desired Specialist Experience

• Experience in mission critical and data centre engineering across new-build, live operational upgrades, technical due diligence, feasibility studies and test fits.
• Exposure to large-scale, multi-megawatt data centre developments - from single 30-40MW buildings through to campus schemes in the 100-600MW range.
• Understanding of hyperscale, colocation and enterprise/research data centre environments and differing client drivers around resilience, flexibility, speed to market and scalability.
• Experience of early-stage site appraisal, masterplanning and test-fit studies, assessing site constraints, utility availability, incoming power, planning, topography, flood risk and plant strategy.
• Knowledge of critical power and cooling infrastructure including HV/MV systems, substations, UPS, generators, PDUs, cooling plant and resilient distribution strategies.
• Experience designing for resilience and uptime, including single points-of-failure reviews, FMEA, concurrent maintainability and Tier-aligned design thinking.
• Interest or practical experience in high-density and AI-ready infrastructure (liquid cooling, direct-to-chip, immersion cooling, hybrid air/water solutions).
• Capability delivering works in live operational environments - plant replacement, refurbishment and phased upgrades while maintaining critical services and uptime.
• Experience of complex campus-scale developments and coordinating multidisciplinary inputs (planning, utilities, sustainability, acoustics, air quality, fire engineering, security, infrastructure).
• Appreciation of energy efficiency and sustainability in mission-critical design - PUE reduction, low-carbon strategies, renewables integration, heat reuse, water efficiency and BREEAM / net-zero objectives.
• Experience working across the UK; interest or experience in international markets (particularly mainland Europe and the Nordics) is desirable.

If this sounds like you and you want to help shape resilient, future-ready data centre infrastructure, we'd love to hear from you.
