Cryogenic Systems Lead

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
Take ownership of the design and integration of the cryogenic plant and cooling systems for Proxima's net energy stellarator, Alpha. This role demands systems thinking, simulation and modelling skills, technical judgement, and the ability to make impactful design decisions. Your deep expertise in thermal analysis and cryogenic plant design will be critical to integrate the advanced cooling systems required to realize Alpha within the ambitious Proxima timelines.

What You Will Do

• Architect and design the integrated cooling systems and plant for the Alpha high temperature superconducting coils and wider cryogenic systems.
• Evaluate high-level systems concepts, conducting trade studies between components within the wider context of the Alpha machine constraints.
• Collaborate closely with the electromagnetic, mechanical and electrical engineers, magnet experts, and physicists both within the Alpha team and across Proxima.
• Use first principles reasoning, simulation, tests and prototyping to detail and validate the design of the Alpha cryogenic system.
• Identify and act as an expert customer for projects with external suppliers and partners to specify and co-design the Alpha cryogenic systems, covering both in-vacuum magnet cooling and the wider cryoplant system, with the highest quality and speed.

Who You Are

• Team players who love challenges and are not afraid to experiment, take risks and learn from mistakes.
• Experience in cryogenic system and plant architecture design, commissioning, and operation within complex large-scale systems and facilities.
• Proven track record in specifying and designing complex cryogenic cooling systems using both multi-physics and reduced-order modelling.
• Experience validating complex cryogenic systems through a combination of simulations, testing, and prototyping.
• Demonstrated ability to lead internal and external work packages within multidisciplinary technical teams in fast-paced, dynamic settings.
