Help us create a better future, quicker!

Join SP Manweb, part of SP Energy Networks, as a Senior Protection and Control Design Engineer and play a vital role in powering the UK's transition to Net Zero. This role sits within our SPM 132kV Networks team, where you'll be accountable for developing safe, compliant and cost-effective protection, control and substation automation solutions across 132kV and associated 33kV networks serving North Wales and the North West of England. 

You'll work on high-value refurbishment, reinforcement, asset replacement and grid access projects that directly enable renewable energy growth. From feasibility through to operational handover, you'll provide authoritative technical guidance on complex, high-impact design packages whilst promoting safety by design, cyber-aware engineering and whole-life asset value. 

This is an opportunity to apply your expertise across the full project lifecycle, working with cutting-edge technology and helping develop the next generation of engineers.

What you'll be doing

• Define protection, control and substation automation requirements across feasibility studies, technical specifications and construction strategies

• Prepare and check detailed designs including protection philosophies, single-line and functional diagrams, AC and DC schematics, interlocking and tripping schemes, wiring diagrams and technical reports

• Undertake and approve protection studies and calculations covering fault levels, protection grading and coordination, current-transformer and voltage-transformer requirements, relay burden and saturation, performance characteristics and scheme effectiveness

• Develop and manage protection and control settings, relay schemes and communication-assisted systems for feeders, transformers, busbars, reactors and customer installations

• Design and deliver IEC 61850-based substation automation solutions, including system architecture, data models, GOOSE messaging, station and process-bus interfaces, configuration files and integration with SCADA and telecommunications systems

• Ensure all designs comply with legislation, CDM designer duties, ScottishPower Safety Rules, SP Energy Networks standards and relevant British, European and international standards

• Identify and reduce foreseeable risks through safety by design, recording residual hazards and considering construction, testing, operation, maintenance, resilience, cyber security and environmental impacts

• Develop technical requirements for procurement, assess submissions and supplier proposals, and provide clear recommendations on technical compliance, interoperability, risk and whole-life value

• Review and check designs, calculations, settings, configurations, drawings and test documentation produced by contractors, consultants, manufacturers and suppliers, ensuring comments and non-conformances are resolved

• Provide technical assistance during manufacture, factory acceptance testing, site installation, commissioning and energisation, resolving site queries and assessing design modifications

• Maintain effective control of technical actions, assumptions, interfaces, design risks, settings and document status, escalating matters that threaten safety, quality, programme or cost

• Contribute to protection and control strategy, standardisation, lessons learned and technical innovation to help shape future practice

• Coach and mentor engineers, designers, graduates and apprentices, delegating work appropriately and providing constructive technical feedback

What you'll bring

• Degree, HNC/HND in Electrical Engineering (or related discipline), or equivalent experience.
• Extensive experience in high-voltage protection and control engineering on UK 132kV and associated 33kV networks.
• Strong technical knowledge of protection schemes, including feeder, transformer, busbar, reactor, switchgear and customer connection protection, alongside control, interlocking and automation systems.
• Experience carrying out and checking protection studies, fault level calculations, grading and coordination assessments, and relay settings using industry-standard software and manufacturer tools.
• Working knowledge of IEC 61850 substation automation, SCADA integration and protection communications systems.
• Experience producing and reviewing protection philosophies, schematics, specifications, settings reports and testing documentation.
• Understanding of CDM requirements, health and safety legislation, utility standards and design risk management.
• Ability to assess supplier and contractor designs, identify technical risks and provide sound engineering recommendations.
• Ability to lead multidisciplinary technical interfaces and clearly communicate engineering decisions to a range of stakeholders.
• Strong project delivery, stakeholder management and mentoring skills, with the ability to prioritise workloads and deliver to programme, cost, quality and governance requirements.
• Professional registration (or working towards IEng/CEng) is desirable.
• Some commissioning experience in testing Protection and Control schemes is desirable.
• Full UK driving licence.
