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.
Join the power movement as a Diagnostic System Owner
The SPARC tokamak design is continually advancing, including the diagnostic systems that will be used to control the plasma and deliver the scientific data necessary to complete the design of ARC. These include approximately 40 sub-systems covering magnetics, interferometry, neutral pressure, x-ray to visible spectroscopy, camera imaging, bolometry, neutrons, Thomson scattering, electron cyclotron emission, reflectometry, Langmuir probes and structural temperature and strain sensing. All systems have completed conceptual design, and many have completed or will soon complete preliminary design. CFS is looking to grow the SPARC team in order to complete final design and shepherd diagnostics through fabrication, assembly, commissioning and utilization. Presently the diagnostics team has enough expertise for baseline support for all major diagnostic systems, but we are looking to add generalists who have experience in multiple diagnostics to ensure our team can deliver measurements on SPARC’s fast timeline. Candidates will work as part of an integrated diagnostic team along with MIT-PSFC partners and fusion community collaborators from around the world to demonstrate net energy from a tokamak for the first time. CFS encourages applications from both senior and early career fusion scientists and those interested in cross-industry career changers to help us build a diverse team to meet our mission goals.
What you'll do:
- Help to shepherd SPARC diagnostic sub-systems through final design, working with a team of scientists, designers, analysts and engineers
- Integrate technical input from experts in the SPARC team to ensure diagnostic designs will be usable to achieve SPARC’s mission goals
- Lead internal and vendor prototyping to verify diagnostic components can survive SPARC’s thermal, structural and neutron environment
- Develop the diagnostic’s assembly, installation, calibration and commissioning plans to ensure SPARC is able to achieve first plasma on-schedule
- Work with the SPARC tokamak operations team to integrate the diagnostic into the plant-level and real-time plasma control systems
- Participate in the testing and operation of diagnostic systems that balances learning how to operate SPARC with obtaining physics results as quickly as possible
- Contribute to a strong safety culture
- Collaborate with CFS designers and analysts as well as provide feedback to academic partners providing input to SPARC diagnostic designs
What we’re looking for:
- Participated in the design of a new or upgraded scientific instrument of the scale and complexity of those used in magnetically confined fusion
- Demonstrated examples of using scientific instruments to support an operational and/or research mission
- Developed software using Python, Matlab, C++ or equivalent for analysis of experimental data
- Relevant hands-on knowledge/skills specific to diagnostic systems listed in summary (e.g. vacuum systems, lasers, calibration lamps, etc.)
- Ability to understand concepts and tradeoffs that bridge engineering and physics
Bonus points:
- Participated in the design and implementation of a diagnostic for a magnetically confined fusion experiment at University-scale or above
Essential Requirements:
- Ability to occasionally lift up to 50 lbs
- Perform activities such as typing, standing, sitting for extended periods of time
- Dedication to safety to mitigate hazards that may include heat, cold, fumes, strong magnets, confined spaces, lasers, microwaves, ionizing radiation, and vacuum/pressure systems
- Willing to occasionally travel or work required nights/weekends/on-call
