Head of Materials: Own the Materials Challenge for a New Reactor
Europe (Netherlands or Central and Eastern Europe) | Permanent | Hybrid with regular travel
Capax Mundi is recruiting for an early-stage advanced reactor developer building its founding team in Europe. The company has a patent-pending, liquid-metal-cooled reactor concept designed around cost from the start, and test facilities lined up with a European research partner. Materials and corrosion are its largest technical risk, and this role owns them.
What you will do
-
Own materials selection and the corrosion strategy for structures, components and fuel in contact with heavy liquid metal
-
Plan and run the test programme, in-house and with partner laboratories, and turn the results into design inputs the engineering team can use
-
Build the materials qualification case and the evidence the regulator and investors will ask for
-
Work closely with the CTO and design engineers, and grow a small materials team as the company scales
What you bring
-
A PhD in materials science, metallurgy, corrosion or a closely related field
-
Hands-on experimental experience in heavy liquid metal (lead, lead-bismuth, lead-lithium) or molten salt environments
-
Experience applying that work in a real project, with a reactor developer, test facility, industrial supplier or fuel vendor, not research alone
-
Comfort with ambiguity and with building something from the start
-
Advantages: fuel cladding or zirconium alloy experience; materials qualification to RCC-MRx or ASME III Division 5; irradiation testing; alumina-forming steels or coatings
Start is flexible, with the first half of 2027 a good fit.
Applications are handled confidentially by Capax Mundi. Contact Imee Carisma, [email protected]
