Original job description

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 we're working with policymakers, suppliers, and many others to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world.

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 Senior Diagnostics Mechanical Engineer

Commonwealth Fusion Systems is assembling the high-field SPARC tokamak, which aims to be the first magnetic fusion device to achieve net fusion energy, and is predicted to be able to achieve high gain and fusion power up to 140 MW. We are completing the design and have begun the assembly and installation of 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. A more detailed overview can be found at: https://pubs.aip.org/aip/rsi/article/95/10/103518/3317155.

CFS is looking to grow the SPARC team in order to complete the mechanical design and integration of these diagnostic systems as they move through design closeout, analysis, procurement, test, and installation. At present we’re finalizing the design and starting assembly for many of the front-end, in vacuum measurement devices and are looking to add multi-faceted support to help carry those designs across the finish line, take on engineering challenges associated with their build and test, and help design the structural components associated with ex-vessel data transmission to our diagnostic labs. Candidates will work as part of an integrated diagnostic team along with fusion scientists and other engineers to demonstrate net energy from a tokamak for the first time. CFS encourages applications from both senior and early career engineers and those interested in cross-industry career changers to help us build a diverse team to meet our mission goals.

What you'll do:

Shepherd SPARC diagnostic sub-systems through design closeout, test, and procurement, working with a team of scientists, designers, analysts and engineers
Integrate technical input from experts on the team to ensure diagnostic designs will survive SPARC’s harsh environments and be usable to achieve SPARC’s scientific mission goals
Coordinate with manufacturing engineers to align on build and test strategy for complex integrated systems, and support builds in the field to maintain quality and speed
Contribute to a strong safety culture

What we're looking for:

Bachelor’s degree in a relevant engineering field (mechanical, aerospace, civil or nuclear)
5+ years of relevant experience designing and delivering mechanical systems
Demonstrated examples of delivering cradle-to-grave mechanical design with nuanced environmental or performance requirements
Experience designing for manufacturing and assembly, and collaborating with partners to oversee or carry out integrated builds
Bias toward action, and a balance of engineering intuition and technical rigor that allows for robust, simple designs to be generated with speed
First principles based approach to engineering and ability to understand concepts and tradeoffs that bridge engineering and physics
Strong communication skills to gather inputs and distribute information across several partner teams

Bonus points for:

Experience with Siemens NX, Teamcenter, or Ansys as CAD, PLM, and analysis tools
Experience with software development, particularly in Python
Experience designing large equipment requiring lifting/rigging tools to assemble
Experience with design of systems for exposure to high stress, UHV, high temperature, high magnetic field, and/or radiation environments

Must-have requirements:

Ability to occasionally lift up to 50 lbs
Perform activities such as climbing, typing, standing, 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

At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.

We value diversity deeply and are proud to be an equal opportunity employer by choice. We consider all qualified applicants equally, regardless of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law.

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.
