Nuclear & Radiological Engineer
About Commonwealth Fusion Systems:
Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.
Combining decades of research, top talent and new technologies, we’re designing and building commercially viable fusion power plants. And working with policymakers and suppliers to build the energy industry of the future.
We’re in the best position to make it happen. Since 2018, we’ve raised over $2 billion in capital – more than any other fusion energy company in the U.S.
Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.
If that’s you and this role fits, we want to hear from you.
Generating net energy plasmas in the SPARC tokamak will involve a skilled team of physicists and engineers designing, building, and operating the tokamak and its many systems. The Nuclear & Radiological Engineer (NRad Engineer) tracks, studies, and engineers the cascade of high energy neutrons, photons, and charged particles generated from DD and DT fusion. NRad Engineers work with multiple engineering disciplines and get to know every part of the SPARC tokamak.
The NRad Engineer is responsible for the delivery of radiation transport analyses to support the design, construction, and licensing of the SPARC fusion device. Discovery of issues and energetic pursuit of solutions is expected from each team member.
This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, “Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws.
This team member will:
- Develop analytical solutions for a range of technical challenges to support all SPARC systems related to nuclear engineering technical areas including radiation transport, shielding design, nuclear heating, and far-field dose calculations
- Perform analysis related to neutronics modeling, radiological engineering, design, and operational health physics
- Be accountable for the quality and accuracy of the previously mentioned work, reports, and presentations
- Provide prompt feedback when a task encounters issues that preclude its timely completion
- Comply with CFS design control processes, including but not limited to: *Documenting analyses in written files *Arranging for check and review of analysis files through submission to M-Files *Upholding high standards of good-faith collaboration and teamwork
The ideal candidate will have most, if not all, of these requirements:
- Bachelor’s degree in Nuclear Engineering, preferably with diverse applications related to radiation transport. (This includes performing calculations that include shielding analyses, dosimetry, nuclear heating etc.)
- An MS or PhD and work experience are beneficial but not required
- Experience with both deterministic and Monte Carlo methods of neutron/photon transport
- Strong analytical skills with fundamental understanding of the first principles of transport methods and nuclear data
- Experience with the following: Python, FORTRAN, C++, Linux
- Experience with common nuclear engineering software, such as MCNP, OpenMC, FISPACT, ATTILA, SCALE, ORIGEN, etc.
- Knowledge of various nuclear codes and standards
- Strong interpersonal and technical communication skills and the ability to work effectively with a wide range of constituencies in a diverse community as well as foster a cooperative work environment
Additional experience and/or qualifications:
- Perform activities such as typing or sitting for extended periods of time
- Willingness to travel or work required nights/weekends/on-call occasionally
- Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
