Senior Plasma Physicist

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 magnet

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.

YOUR IMPACT

We are seeking a highly skilled and motivated Senior Plasma Physicist to join our stellarator design team at Proxima Fusion. We are designing a net-energy stellarator as a research and engineering platform on the path toward a fusion power plant.

This role is crucial to driving our mission to design, build, and operate the device. As a Senior Plasma Physicist, you will lead the conceptualization and development of key scientific analysis workflows and contribute to novel research in magnetic confinement fusion.

Proxima Fusion is committed to publishing its scientific results to accelerate the entire fusion ecosystem, openly collaborating with academic partners, and contributing to public trust in fusion energy.

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.

WHAT YOU WILL DO

• Contribute to the definition of requirements and conceptualize the design of critical stellarator components such as heating systems and divertors.

• Develop and enhance our physics and engineering simulation stack.

• Collaborate with partners from public institutions to foster innovation and knowledge exchange.

• Mentor team members and guide them in achieving project milestones.

WHO YOU ARE

• We are looking for high performers who love challenges and see these as learning opportunities.

• It is important not to be afraid to experiment, take risks and learn from mistakes. We believe in continuous iterations and getting things done.

• Hold a PhD in Plasma Physics, Nuclear Engineering, or a related field, with a focus on magnetic confinement fusion—preferably on a toroidal confinement device.

• Have demonstrated expertise in one or more of the following areas: core transport, plasma heating, MHD, edge physics, or scenario development.

• Possess strong problem-solving skills and the ability to make informed decisions in a fast-paced environment.

• Have excellent communication skills, with the ability to collaborate effectively within a multidisciplinary team.

INTERVIEW PROCESS
