Electrical Design Engineer

Fohntech Group are looking for an Electrical Design Engineer to join their team in Belgium. The Electrical Design Engineer will support the delivery of large-scale hyperscale data centre campuses, providing technically robust, standardised, and resilient electrical designs that meet strict client performance, availability, and operational requirements.

The role focuses on repeatable design solutions, high-capacity power infrastructure, and close coordination with client, vendor, and construction teams.

Key Responsibilities

Hyperscale Electrical Design Develop electrical designs for hyperscale data centre buildings and campuses from concept through IFC and as-built stages. Deliver high-capacity and high-resilience electrical systems including: Utility intake and on-site HV substations MV/LV distribution architectures Large-scale UPS and battery systems Standby generation plants and fuel systems interfaces EPMS, metering, and power quality monitoring Apply and maintain standardised client design templates and basis-of-design documents.

Redundancy, Resilience & Capacity Planning Design electrical systems to meet hyperscale redundancy strategies (N, N+1, 2N, 2N+1). Support power density planning and future capacity expansion strategies. Evaluate system performance, fault levels, selectivity, and short-circuit coordination. Design Governance & Client Standards Ensure designs fully comply with hyperscale client standards, technical specifications, and change control processes.

Support client design reviews, technical gateways, and approval milestones. Manage deviations, concessions, and technical risk registers. Multi-Discipline & Vendor Coordination Coordinate with mechanical, CSA, ICT, BMS, fire, and commissioning teams to ensure integrated solutions. Engage with OEMs and vendors (UPS, generators, switchgear) during design development.

Review vendor and specialist subcontractor designs for compliance and constructability. Construction & Site Engineering Support Provide ongoing technical support during construction, installation, and commissioning. Respond to RFIs, technical queries, and site-driven design changes. Attend site inspections, factory acceptance tests (FATs), and witness testing as required.

Testing, Commissioning & IST Support development of commissioning strategies and integrated systems testing (IST). Review test scripts and ensure alignment with client operational requirements. Support phased energisation, building-by-building, and campus-wide handovers. Value Engineering & Programme Support Contribute to value engineering while protecting hyperscale performance and reliability requirements.

Support procurement strategies and long-lead equipment coordination. Provide technical input into construction sequencing and programme planning. Key Skills & Competencies Strong understanding of hyperscale electrical architectures and utility interfaces. Experience with high-capacity power systems and campus-scale infrastructure.

Ability to work within strict client governance and change control environments. Excellent coordination, documentation, and stakeholder management skills. Strong analytical and engineering judgement.

Qualifications

& Experience Degree in Electrical Engineering or equivalent. 4–8 years’ experience in hyperscale data centres or large-scale mission-critical projects. Experience working with hyperscale clients, major contractors, or Tier 1 consultants. Proficiency in BIM-led design environments (Revit, AutoCAD) and electrical analysis tools.

Working knowledge of standards such as IEC, BS, IEEE, NFPA, TIA-942, and Uptime Institute. Chartered Engineer or actively working toward chartership desirable. Personal Attributes Detail-focused with a strong appreciation for standardisation and repeatability. Confident engaging with demanding hyperscale clients and technical reviewers.

Calm, methodical, and solutions-driven under programme pressure. Strong ownership mindset and pride in engineering quality. Next Steps If you are interested in this role, please apply directly or email your CV to careers@fohntechgroup.com
