Lead Electrical Engineer - Battery Systems; SMR

Position: Lead Electrical Engineer - Battery Systems (SMR)
Provide technical expertise across the full lifecycle of Uninterruptible Power Supply (UPS) systems within a highly regulated, safety-critical engineering environment. The role covers delivery of complete UPS system designs, including system architecture, sub-system development, equipment specification, equipment selection, integration, verification, and validation activities.
Working within multidisciplinary engineering teams, you will apply a structured systems engineering approach to develop robust and compliant critical power solutions from concept through to final verified design.

Key Responsibilities

Translate high-level plant and operational requirements into detailed technical specifications for UPS and associated electrical power systems.
Collaborate with process, mechanical, controls, safety, and electrical engineering disciplines to develop integrated system solutions.
Provide technical leadership and engineering guidance for UPS system design activities.
Develop and assess system architectures, equipment specifications, and design substantiation documentation.
Ensure designs comply with applicable international standards and regulatory requirements, including IEC 63046, IEC 61225, and IAEA SSG-34 guidance.
Produce verification and validation strategies, including inspection, testing, commissioning, and acceptance plans.
Support lifecycle engineering activities covering design, procurement, installation, operation, maintenance, and future upgrades.
Contribute to safety case development and technical interactions with regulators, independent assessors, and external stakeholders.
Support supplier and contract partner management activities, acting as an intelligent customer where required.
Provide mentoring and technical support to junior and developing engineers.

Experience & Skills Required

Strong background in UPS systems, critical power infrastructure, or industrial electrical power systems.
Experience delivering systems engineering activities within regulated or safety-critical industries.
Understanding of electrical system integration, power continuity, battery systems, and equipment qualification processes.
Familiarity with verification, validation, and requirements management methodologies.
Knowledge of relevant IEC and international engineering standards.
Ability to work effectively across multidisciplinary engineering teams.
Experience supporting safety case or regulatory compliance activities is desirable.
Previous experience managing suppliers, contractors, or technical work packages would be advantageous.

Experience with in nuclear, defence, aerospace, rail, automotive, oil & gas, or similarly regulated sectors is beneficial.

Additional Information

Role involves working across the full lifecycle of safety-classified and non-classified UPS systems.
Opportunity to act as a responsible designer and technical authority depending on project scope.
Responsibility for delivery of defined engineering work packages and programme milestones.
May involve oversight of external engineering partners and technical review activities.
Opportunity to coach and mentor less experienced engineers while supporting wider engineering capability development.
Flexible and hybrid working arrangements may be available depending on project requirements and site access needs
