Magnet Lead at Stealth Deep Tech Startup (Early Hire)

First Momentum Ventures is hiring for a pre-seed Deep Tech startup industrialising fusion and turning Sci-Fi machines into manufacturable, repeatable products.

At the centre of this strategy is the industrialisation of high-field superconducting magnet systems, to unlock compact fusion and near-term commercial applications in medical imaging and industrial inspection.

Backed by First Momentum, Europe’s leading early-stage deep tech investor, the founding team is now hiring its first technical engineer as it moves from research concept to prototype hardware.

Tasks

• System-level architecture of the HTS magnet platform

• Design, development, and validation of HTS coils for fusion and MRI-class applications

• Demountable superconducting joint development

• Quench detection, protection, and instrumentation

• Prototype campaigns from bench experiments to sub-scale hardware

• Defining the path from early prototypes toward repeatable, industrialised production

Requirements

Must-haves

• Deep experience with superconducting magnet systems (HTS preferred; strong LTS fundamentals acceptable)

• Demonstrated ownership of real hardware: built, tested, debugged, iterated

• Familiarity with REBCO/HTS materials, coil winding, quench protection, and superconducting instrumentation

• Comfortable with high autonomy and low structure at an early-stage company

Nice-to-haves

• Experience bridging research and product development

• Interest in design-to-manufacture and industrialisation of advanced systems

Typical backgrounds: magnet design engineers, applied superconductivity researchers, HTS system developers, or research engineers ready to build products instead of papers.

Benefits

Huge opportunity as employee #1

This is a full-ownership, hands-on role for an engineer who wants to define a magnet program from scratch. You will work directly with the CEO and COO, set the technical direction, and build the team around you as the company grows.

Why This Is Rare

Most magnet roles sit inside large programs with narrow work packages. This is the opposite: we offer full technical ownership of a magnet system that will define the architecture of a next-generation fusion device, with direct input into how industrialised superconductivity gets built in practice. Competitive salary, meaningful equity, and a founding team role with real compounding impact.
