Our Mission

At Rolls‑Royce SMR, we are transforming the future of clean energy by developing next‑generation nuclear technology that will deliver reliable, low‑carbon power for generations to come. As part of our growing organisation, you will help solve complex engineering challenges that support energy security, sustainability and global net zero ambitions.

The Team

You will join our Plant Equipment Engineering team as we continue to build specialist capability across key technical disciplines. Working within a multidisciplinary environment, you will collaborate with engineers, programme teams, suppliers and stakeholders to deliver critical backup power solutions that support the Rolls‑Royce SMR programme.

The Role

This is a specialist engineering position focused on Emergency Diesel Generator (EDG) and Ultimate Diesel Generator (UDG) systems rather than general plant equipment. You will provide technical leadership across the specification, integration, design and delivery of large‑scale diesel generator systems, helping to ensure safe, reliable and compliant backup power solutions within a highly regulated environment.

What We’ll Need You to Do

Lead the specification, integration and delivery of diesel generator systems and associated fuel, lubrication and oil system equipment. Work closely with suppliers and internal stakeholders to develop requirements, review designs and ensure technical solutions meet programme needs. Provide subject matter expertise on EDG and UDG systems, supporting complex engineering decisions and resolving technical challenges. Apply appropriate governance, quality standards and engineering best practice throughout the product lifecycle. Support programme delivery by managing risks, driving technical maturity and collaborating across multiple engineering disciplines.

What You’ll Bring

A degree, HND or equivalent qualification in Mechanical Engineering or a related discipline. At least five years of engineering experience, including direct involvement with emergency diesel generators, backup power systems or similar critical infrastructure. Experience designing, specifying, integrating, procuring or overseeing large‑scale diesel generator systems and supporting equipment. Technical expertise gained within nuclear, power generation, marine, industrial power or data centre environments would be highly valued. The credibility to operate as a recognised technical specialist, coupled with strong collaboration and stakeholder management skills.

Salary and Package

The salary band for this role will be between £50,650 – £66,500 dependent on the skills, values and knowledge you bring. There may be flexibility with the starting salary in exceptional cases, and the role may develop further as the programme grows.

• Bonus – Performance‑related target opportunity up to 12.5%
• Benefits Allowance – £2,200 per annum for a bespoke package
• Pension – 12% employer and 6% employee contributions
• Holidays – 29 days (+ public holidays) with the ability to buy or sell up to 4 days
• Private Medical Insurance – BUPA single cover
• Life Assurance – 6× pensionable pay
• Home Office Support – £250 one‑off payment for new starters
• Pay Range: £50,600.00 - £66,465.00
