Materials Lead Engineer

WHO WE ARE

At Proxima Fusion, we're driven by a bold mission – to redefine the future of sustainable energy. Our unique concept, built upon the groundbreaking W7-X stellarator and the latest advances in technology, paves the way for commercially viable fusion power plants.

What’s more, our work in stellarator optimization, powered by cutting‑edge computation and machine learning, is propelling us into uncharted territories of fusion technology. New higher performance design points are unlocked by high temperature superconducting magnets.

To fully grasp this huge opportunity, we’re building a team of extremely dedicated and passionate people who come together driving something extraordinary, radically transforming technology in the world.

WHY JOIN PROXIMA FUSION

- You will get to work on some of the most complex tech challenges to bring abundant, safe, clean energy to the world.

- You'll get to join and learn from an exceptional selection of accomplished and driven individuals.

- Do your life’s best work and enjoy the journey.

- Get to show that big things are possible in Europe when you assemble the best talent.

YOUR IMPACT

As a Materials Engineer experienced in both the properties of fusion‑relevant materials and their joining and manufacture, you will provide the expertise required to select the materials for the Proxima net energy stellarator, Alpha. Through external collaborations and internal prototyping and testing, you will lead the selection and verification of the materials, manufacturing and joining techniques that will enable the delivery of Alpha within the ambitious Proxima timelines.

WHAT YOU WILL DO

- Provide recommendations for the Alpha core stellarator systems materials through detailed reviews of the materials, joining and component manufacturing processes, and close collaboration with Alpha system designers. This will include structural, shielding, coating, plasma facing, high temperature and and cryogenic materials

- Manage and act as an expert customer for external contracts to deliver the data and materials, joining and manufacturing demonstrations required to design and operate the Alpha stellarator.

- Own, populate and maintain the Proxima materials database, ensuring that the data is traceable, verified, and sufficient to enable the demonstration of net energy during Alpha operations.

- Lead the Alpha materials qualification and verification strategy.

WHO YOU ARE

- High performers who love challenges and are not afraid to experiment, take risks and learn from mistakes.

- Experienced materials engineers with the ability to make materials recommendations for a broad range of environments and system requirements. You will ideally have a background in fusion‑relevant materials, including some or all of the following environments: high temperature, high‑energy neutrons, plasma facing, cryogenic and vacuum.

- Experience in materials characterisation, testing and prototyping to obtain material properties and/or verify joining and manufacturing techniques.

- Knowledge of materials standards and the methods needed to qualify materials.

- Demonstrated ability to manage contracted external work packages within multidisciplinary technical teams in fast‑paced, dynamic settings.
