Design the HVAC systems that enable next-generation nuclear power plants.

We’re supporting a confidential organisation at the forefront of Small Modular Reactor (SMR) development, expanding its engineering team as part of a major next-generation nuclear programme.

This role sits within a multidisciplinary design environment and focuses on the HVAC systems that support safety, operability, and long-term reliability across nuclear power plant buildings. You’ll work closely with mechanical, electrical, civil, safety, and licensing teams to ensure systems are fully integrated and nuclear-grade.

Perhaps you’re currently designing HVAC systems for industrial or energy projects, but feel limited by repetitive building types, shallow interfaces, or a lack of exposure to full plant lifecycle design. This role offers a step into technically demanding SMR projects where HVAC is treated as a critical system — not a late-stage utility. You’ll contribute to breathing air calculations, leakage assessments, pressure loss analysis, and equipment specification, all within a regulated nuclear framework.

The work includes hands-on system design, vendor engagement, review of P&IDs and ducting diagrams, and collaboration with contractors developing detailed solutions. You’ll also be part of a U.S. government-supported advanced reactor programme, where quality, integration, and engineering judgement matter. If you have a solid HVAC engineering foundation and are curious about applying it to nuclear-grade design — even if you haven’t worked in nuclear before — we’d be glad to have a conversation.

Candidates must have UK right to work for the Bristol role.
