• Own and develop the industry contracts and partnerships required to deliver the Alpha fuel cycle.
• Develop and lead on tritium accountancy in Alpha including quantification of tritium permeation and retention; and its impact on the Alpha plant and program.
• Technically lead first principles reasoning, modelling, tests and prototyping to detail and validate the design of the Alpha fuel cycle system.
• Provide expert input to the Alpha safety case related to tritium containment best practice.
• Build an innovative and inclusive team within Proxima and strong collaborations with external suppliers, to achieve the ambitious Alpha milestones.

WHO YOU ARE

• Visionary team player with the ability to lead internal and external work packages within multidisciplinary technical teams in fast-paced, dynamic settings.
• Deep understanding of fusion fuel cycles, with knowledge of tritium gas exhaust processing, separation, storage, accountancy and containment.
• Proven success in procuring and commissioning tritium equipment.
• Experience developing and owning tritium accountancy frameworks, including quantification of permeation and retention.
• Experience validating fuel cycles systems through a combination of simulations, testing, and prototyping.

INTERVIEW PROCESS
