Lead Electrical Engineer - Uninterruptible Power Supply Systems

Role Title: Lead Engineer – Battery Systems

We are Rolls‑Royce SMR and we’re doing something that’s never been done before. We’re revolutionising an industry. That’s a once‑in‑a‑career opportunity for those excited by such a challenge. This is more than just a job; this is a legacy.

The Electrical Engineering team at Rolls‑Royce SMR is responsible for designing and delivering electrical systems that underpin safe, resilient and reliable power station operation. Battery and UPS systems are essential components within this architecture, supporting both safety‑classified and non‑classified functions across the plant.

About The Role

As a Lead Engineer for Battery Systems, you will provide technical expertise across the lifecycle of Battery and Uninterruptible Power Supplies (UPS) systems for the SMR nuclear power plant. This covers delivery of the complete design — spanning system architecture, sub‑system design, equipment specification and system selection — to realise the final verified design of the power station. You will achieve this by working closely with engineering teams from across the power station and applying a structured, systems‑engineering approach to design.

You will translate high‑level requirements into battery and UPS system specifications, ensure compliance with international standards (including IEC 63046, IEC 61225 and SSG‑34), and lead verification and validation planning. The role includes responsibility for supporting the safety case, acting as an intelligent customer when managing contract partners, and providing electrical technical leadership within the team. You may also coach and mentor less experienced engineers and contribute to procurement, operational and maintenance considerations.

We’ll Need You To

• Work with process and mechanical systems engineers to translate high‑level requirements into Battery and UPS system specifications
• Liaise across engineering disciplines to understand functional performance and integrate systems effectively
• Provide electrical technical leadership for Battery/UPS systems in support of the team manager
• Assess and substantiate that battery system designs and specifications meet all applicable requirements
• Ensure compliance with key industry standards including IEC 63046, IEC 61225 and SSG‑34
• Produce verification and validation plans and define test plans to demonstrate system requirement satisfaction
• Support planning and implementation of lifecycle policies and procedures for battery and UPS systems
• Ensure optimum solutions across procurement, operations and maintenance aspects of battery and UPS equipment
• Contribute to safety case development and engage with regulators and independent nuclear safety assessors
• Act as a responsible designer or intelligent customer depending on the task
• Deliver agreed programme work and manage suppliers or contract partners where required
• Coach, mentor and provide technical guidance to less experienced engineers in the electrical capability

Key Skills Required

We know there’s no such thing as the ‘perfect’ candidate. If you meet around 75% of the criteria below, we’d love to hear from you:

• Experience across the lifecycle of battery or UPS systems in a highly regulated industry; nuclear experience desirable but not essential
• Deep knowledge and significant experience in battery and UPS system design, including specification, assessment, verification, testing, installation, commissioning and maintenance
• Expertise in one or more relevant sub‑disciplines: battery systems, UPS systems, protection systems, earthing systems and electrical distribution systems
• Good understanding of designing systems to be functionally resilient to faults (redundancy, diversity etc.)
• Knowledge and experience in applying relevant standards such as IEC 63046 and IEC 61225, and understanding related regulatory frameworks
• Experience applying systems engineering methodologies, including MBSE, to electrical systems
• Strong communication skills, able to interpret and present complex technical information clearly, including to regulators
• Ability to act as an intelligent customer and provide technical oversight of supply chain partners
• Degree‑qualified in electrical engineering, electronics or a related discipline, or equivalent experience

We welcome applicants at different levels of experience and from across regulated sectors.
