Volantes Renewables Recruitment is partnering with a leading UK & Ireland EV charging infrastructure and grid connections contractor to appoint an experienced Tendering & Design Engineer specialising in high voltage networks up to 33kV.

• Develop detailed engineering drawings in AutoCAD — single line diagrams, GA layouts, schematics and wiring diagrams.
• Coordinate with structural and civil designers to integrate substation infrastructure and cable routes.
• Liaise with DNOs / IDNOs and ensure designs comply with ENA, BS, IEC and relevant DNO design standards.
• Prepare detailed bills of quantities and cost estimates alongside the estimating team.
• Develop construction design packs incorporating in-house and third-party input for delivery teams.
• Identify and eliminate risk across construction, operational and decommissioning phases.
• Provide technical input at tender evaluations, client meetings and design reviews.
• Ensure all designs meet health, safety, environmental and quality standards.
• Maintain up-to-date knowledge of industry standards and best practice.

ESSENTIAL REQUIREMENTS

• Degree in Electrical Power Engineering, or HNC/HND with extensive HV design experience.

• Proven experience in 33kV substation layout, protection & control, earthing design and auxiliary systems.

• Strong understanding of HV plant equipment — transformers, switchgear, CTs/VTs and similar.
• Experience liaising with DNOs / IDNOs for design submissions and approvals.
• Full UK driving licence.

DESIRABLE

• Experience preparing and reviewing protection studies and earthing reports.
• Experience with SCADA projects, PV schedule design or energy conversion systems.
