Senior Mechanical Engineer – Superconducting Magnet Systems

Stax Talent is working with a well-funded deep tech company in the energy sector to hire a senior mechanical engineer for its superconducting magnet programme.

The opportunity

Our client is developing large-scale superconducting magnet systems for a next-generation energy application. The engineering team is experienced and growing, and the programme is moving from early development towards larger prototype hardware.

This is a hands‑on ownership role. You'll take responsibility for the mechanical side of magnet and cryogenic hardware, and you'll have a real influence on how the engineering function develops.

What you'll be doing

• Leading the mechanical design of magnet structures, supports, cryostats, vacuum enclosures and test equipment.
• Designing for demanding combined loads: electromagnetic, thermal and pressure.
• Taking hardware from concept and analysis through manufacture, assembly and testing.
• Setting technical direction for CAD and simulation work, and reviewing others' designs.
• Contributing to wider system-level design and to the company's engineering processes and standards.

We're looking for

• A degree in mechanical, aerospace or a related engineering discipline, or equivalent experience.
• 5+ years of mechanical design experience on high-load structures, in industry or research, with real hardware feedback.
• Proven ownership of components or assemblies through design, build and test.
• Strong analytical skills: hand calculations plus FEA (ANSYS, Abaqus, COMSOL or similar) under combined mechanical and thermal loading.
• Solid 3D CAD skills, plus fluency with drawings, tolerances and fits.
• Confidence making and documenting engineering decisions with incomplete information.
• Fluent English. German is not required.

Highly relevant backgrounds

• Superconducting or high-field magnets, for example accelerator, medical imaging or research magnets.
• Cryogenic, vacuum or pressure vessel design, ideally including code-based design.
• Electrical machines or other systems with large electromagnetic loads.
• First-of-a-kind hardware development in a scale-up, research lab or advanced engineering environment.

What's on offer

• Technical ownership and the chance to shape a growing engineering team.
• Challenging, first-of-a-kind hardware with real-world impact.
• A competitive package and modern office and lab facilities.
