Your new role

As our new Technical Director – Critical Systems, you will play a pivotal role in leading and developing Ramboll’s electrical design capability across the Industrial, Healthcare, Government, Marine, and infrastructure sectors. You will provide specialist expertise in High Voltage (HV) systems up to 33 kV, Low Voltage (LV) networks, and critical power systems including UPS and standby generation. You will also guide clients in improving resilience, redundancy, and reliability, while supporting the decarbonisation and electrification of private networks. Your work will cover the full lifecycle of private power distribution systems, from concept and feasibility studies through detailed design, commissioning, and operational optimisation.

Key areas of focus

• Design and specification of HV substations up to 33 kV, including switchgear selection, transformer sizing, protection coordination, and earthing system design.
• Production and review of single-line diagrams (SLDs) and network protection studies, ensuring compliance with ENA, IEC, and BS standards.
• Technical leadership for resilient electrical systems, incorporating redundancy topologies (N+1, 2N) and mitigation of single points of failure.
• Guidance on private HV network connections to Distribution Network Operators (DNOs), including G99/G100 compliance, load flow analysis, and fault level management.
• Supporting clients in future-proofing their electrical infrastructure for low-carbon technologies such as battery storage, renewable integration, and electric vehicle charging.
• Leading technical assurance and governance to maintain the highest standards of quality across all electrical deliverables.

Your key responsibilities

• Act as the UK electrical subject matter expert for all Critical Systems projects up to 33 kV.
• Lead concept, feasibility, and detailed designs for HV and LV power distribution systems in mission-critical and industrial environments.
• Develop and review equipment specifications, protection philosophies, and earthing and bonding designs.
• Undertake and review network modelling and analysis, including:

• Protection coordination studies
• Short-circuit and fault level calculations
• Load flow and power quality studies
• Arc flash hazard analysis and mitigation strategies

Your new team

You will join a skilled, multi-disciplinary technical team working alongside project managers and engineers across multiple offices and regions. You’ll be the go-to authority on HV systems and resilient electrical design, supporting colleagues in delivering technically excellent and sustainable outcomes for clients. Our team’s mission is to improve the efficiency, reliability, and sustainability of electrical infrastructure while supporting the UK’s net-zero transition. We work across the project lifecycle—from feasibility studies through to detailed design, commissioning, and operational optimisation.

• Proven experience in private HV networks up to 33 kV, including substation design, switchgear specification, and protection coordination.
• Chartered Engineer (CEng) status, ideally with the IET.
• Proficiency in power system analysis software such as ETAP, Trimble or equivalent.
• Demonstrated capability in protection studies, fault analysis, load flow, and arc flash assessments.
• Strong understanding of resilience and redundancy architectures (N+1, 2N) and their application to critical systems.
• Experience with DNO interfaces, G99 compliance, and relevant ENA standards.
• Knowledge of low-carbon and energy transition technologies, including battery energy storage systems (BESS) and renewable integration.
• Excellent communication and stakeholder management skills, with the ability to translate technical detail into clear commercial and operational outcomes.

What we can offer you
