• Drive engineering governance and ensure compliance with project specifications, industry standards, statutory requirements, and assurance processes.
• Lead technical resolution of RFIs, EWNs, NCRs, design changes, technical queries, and interface issues.
• Undertake and lead constructability reviews, value engineering initiatives, and risk mitigation activities throughout design and construction phases.
• Provide strategic oversight of subcontractors, suppliers, and installation teams to ensure safe, efficient, and compliant delivery.
• Support procurement strategy, technical evaluations, equipment selection, supplier engagement, and approval processes.
• Lead development and review of RAMS, ITPs, quality plans, testing strategies, energisation plans, commissioning procedures, and handover documentation.
• Monitor project progress, identify engineering risks and opportunities, and provide recommendations to senior project leadership.
• Manage complex interfaces across civil, structural, architectural, systems, telecommunications, signalling, traction power, and MEP disciplines.
• Chair technical workshops, design reviews, coordination meetings, and stakeholder engagement forums.
• Support systems integration, testing, commissioning, energisation, and operational readiness activities.
• Mentor and provide technical guidance to electrical engineers, design coordinators, and graduate engineers.
• Contribute to engineering best practice, lessons learned, innovation initiatives, and continuous improvement across the programme.
• Ensure electrical safety principles are embedded throughout design, installation, testing, commissioning, and operational handover activities.

• Degree qualified in Electrical Engineering or a related discipline.
• Significant experience delivering electrical systems on major infrastructure, rail, tunnelling, utilities, transportation, energy, or heavy civil engineering projects.
• Proven experience leading multidisciplinary engineering teams and managing complex stakeholder environments.
• Strong technical knowledge of HV/LV electrical distribution systems, substations, switchgear, protection systems, standby power generation, UPS systems, lighting, and electrical building services infrastructure.
• Extensive experience in design management, technical assurance, and construction delivery.
• Strong understanding of engineering standards, specifications, design verification, and systems assurance processes.
• Ability to review and approve complex technical documentation, calculations, drawings, and BIM models.
• Experience managing contractor, consultant, and supplier performance.
• Strong understanding of QA/QC, testing, commissioning, energisation, and handover processes.
• Excellent communication, leadership, negotiation, and stakeholder management skills.
• Strong knowledge of relevant standards including BS 7671, IEC standards, EN standards, and applicable rail or infrastructure electrical requirements.

• Chartered Engineer (CEng) status or working towards chartership.
• Experience working on major rail, tunnelling, or transportation infrastructure projects.
• Knowledge of HS2, Network Rail, London Underground, National Grid, or equivalent major infrastructure standards.
• Experience with systems integration, assurance, and commissioning of complex infrastructure assets.
• Familiarity with BIM coordination, digital engineering, and common data environments.
• Experience leading technical governance and engineering assurance reviews.
• Experience of HV authorisation processes and electrical safety management systems.
• Knowledge of traction power, station electrical systems, or tunnel electrical infrastructure.

• Strong technical leadership and engineering judgement.
• Strategic and solutions-focused mindset.
• Ability to influence senior stakeholders and drive technical decision-making.
• Strong commercial, programme, and risk awareness.
• Excellent coordination and multidisciplinary interface management skills.
• Commitment to quality, safety, and engineering excellence.
• Ability to manage multiple workstreams and priorities within a complex project environment.
• Strong focus on electrical safety, operational resilience, and asset performance.
