Job Description

Drive experimental strategy while remaining deeply hands-on at the forefront of fusion research. This senior scientist will both lead and contribute to several experimental physics projects to advance the physics basis for the high-field axisymmetric mirror. This work will include designing, building, and fielding new experimental diagnostics on the currently operating Wisconsin HTS Axisymmetric Mirror (WHAM) at the University of Wisconsin-Madison, proposing new experimental campaigns and plasma diagnostics needed to enhance physics understanding and validation efforts with computational tools, and helping design and diagnose of future axisymmetric mirror devices at Realta Fusion called Anvil and Hammir. This role will include leading and participating in collaborations with external research groups at both national laboratories and universities, publishing work in peer-reviewed journals and disseminating results at conferences.

Job Responsibility

  • Develop complex research methodologies and procedures to identify solutions in a magnetic mirror fusion research device and optimize the design of Realta’s next fusion devices
  • Design, build, and field new plasma diagnostic systems on WHAM at the University of Wisconsin-Madison and for our future fusion devices called Anvil and Hammir
  • Collect and analyze highly complex research data, propose and conduct experiments, and document results according to established policies and procedures
  • Interface with theory and modelling, engineering team and business leadership to deliver on technical milestones
  • Conduct literature reviews, prepare reports and materials and disseminate information to appropriate entities

  • Contribute to the establishment of company safety standards and implement these standards within the R&D team
  • Foster a positive and inclusive work environment that aligns with the company's mission, values, and sustainability goals, promoting innovation, collaboration, and employee engagement

Requirements

  • PhD in Plasma Physics, or a related field + minimum of 5 years' experience in experimental plasma physics research
  • Extensive experience with standard plasma diagnostics (e.g. bolometers, electrostatic ion energy analyzers, interferometers, magnetic probes, spectrometers, visible imagery, fusion neutron diagnostics, soft and hard x-ray detectors, Thomson scattering, etc…) and analysis techniques
  • Understanding of magnetically confined fusion plasma heating and current drive technologies, such as bias-induced rotation, electron cyclotron heating, neutral beam injection, and RF heating
  • Exceptional interpersonal and communication skills (written and verbal) to collaborate effectively with colleagues, external partners, and stakeholders
  • Demonstration of innovation capacity through IP generated and/or publications in the field

What we offer

  • Competitive compensation package, including equity stock options
  • Comprehensive benefits including health, dental, and vision insurance, plus a 401(k)
  • Flexible paid time off (PTO) to support work-life balance
