Do you want to be a part of a growing team delivering sustainable electricity supplies Can you collaborate across diverse international project teams Are you experienced in high voltage electrical design for UK substations and cabling Then join us to shape a sustainable and liveable world.

Create Solutions that will enable a better tomorrow
To enable faster grid connections and resilient energy systems we are looking for a High Voltage Engineer to join us. Your primary task will be to supervise engineering work related to the design of electrical transmission systems including substations and high voltage cabling. Your role will be focused on the design environment which while based in the UK will involve interacting day-to-day with colleagues across our global hubs. There may also be opportunities to broaden your contribution to other areas within the electrical discipline in a variety of major infrastructure and energy sector settings.

Your key responsibilities will be:

• System Design & Calculations:
  Lead and perform detailed electrical design calculations for Medium and High Voltage substations and power distribution systems. This includes but is not limited to cable sizing voltage drop power factor correction thermal analysis earthing/grounding and insulation coordination.
• Short Circuit & Load Flow Studies:
  Conduct short circuit load flow and arc flash studies using industry-standard software tools such as ETAP Power Factory SKM Power Tools or equivalent.
• Protection Coordination:
  Develop protection philosophies and perform relay coordination studies for MV/HV networks. Specify and select protective relays current and voltage transformers and design protection schemes for substations feeders transformers and other critical assets.
• Documentation & Reporting:
  Prepare technical reports calculation summaries protection and control single line diagrams and relay settings documentation in accordance with relevant codes and standards (e.g. IEEE IEC NEC NESC).
• Compliance & Standards:
  Ensure all designs and studies align with applicable industry standards utility requirements and client specifications. Actively monitor developments in codes and best practices related to MV and HV electrical systems.
