We’re supporting a leading organisation in advanced nuclear technologies that is progressing a first-of-a-kind Small Modular Reactor from detailed design through licensing and into delivery.

As a Valve Engineer, you’ll sit within a systems engineering centre of excellence, shaping how safety-critical mechanical components perform across the full plant lifecycle.

You may already be working in nuclear or heavy industry, responsible for specifications or component reviews, but finding that your role is limited to narrow scopes, legacy plants, or late-stage changes. Perhaps you want earlier technical influence, closer interaction with system design, or a clearer line of sight between your decisions and a licensed nuclear facility. This role offers exactly that. You’ll develop and own valve requirements and procurement specifications, work directly with manufacturers, and support licensing-grade design for a new reactor platform. Your work will influence operability, maintainability, outage performance, and long-term plant reliability, not just compliance on paper.

Technically, the role sits at the intersection of system engineering, mechanical design, and nuclear regulation. You’ll engage with ASME BPVC, API, MSS, nuclear QA requirements, and regulator-facing documentation, while collaborating across reactor, balance-of-plant, and auxiliary systems. Exposure to industry tools and system codes is part of the environment, alongside hands-on engineering judgement.

If you have solid valve engineering fundamentals and want to apply them where design decisions still matter, on a programme that will define the next generation of nuclear build, we’d be glad to have a confidential conversation.

Capax Mundi supports engineers working on meaningful, long-term contributions to the global energy transition.
