Energy Group is mission-driven to provide sustainable, affordable
fusion power to the world. The company was formed in 2019 by a team
of globally-recognized fusion scientists with a strong track record
of building state-of-art stellarator fusion machines, together with
veteran business leaders experienced in successfully scaling
companies and commercializing energy technologies. If you are
searching for the best new ideas and share our vision, join us as a
“ Nuclear Engineer ”. This is what you need to know: Location:
Knoxville, TN (other office locations may be available) Salary:
Highly Competitive Plus Benefits Contract: Permanent, full time
Reporting to: Director of Nuclear and Fuel Cycle Your role in the
mission: Type One Energy is seeking a highly motivated Neutronics
Engineer with education in radiation transport analysis to support
the design, construction, and licensing of Type One Energy
high-field stellarator systems. Ideally the candidate will have
knowledge in radiation transport codes and their uses for solving
nuclear challenges related to performance and safety. As a
Neutronics Engineer, you will play a vital role in the development
of our nuclear analysis program in support of both our near-term
Infinity One Project and longer-term Fusion Pilot Plant. Assist in
the development of computational solutions for a range of nuclear
challenges related to both D-D and D-T fusion devices, including
radiation particle transport, radiation damage, nuclear heating,
nuclear activation and decay heat analysis, shielding design, dose
calculations. Perform analyses on neutronics modelling,
radiological engineering, nuclear design, and operational health
physics. Utilize advanced radiation transport tools to evaluate and
characterize the impact of multivariate design choices (including
materials, geometry, and operational conditions) on performance
metrics. Support in-depth research and analysis on a variety of
nuclear design strategies for fusion systems as it relates to
