Your new role

As our new Technical Director Critical Systems you will play a pivotal role in leading and developing Rambolls 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 will include:

• 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 (N1 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 will be:

• 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
