About the company:

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.

CFS is collaborating with MIT to leverage decades of research combined with new groundbreaking high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost.

The mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change.

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 Build Engineer

The design of the SPARC facility is continually advancing, including the design of instrumentation that will be used to control the plasma and deliver the scientific data necessary to inform the design of ARC. The SPARC Diagnostic system is comprised of over forty sub-systems that use a variety of proven techniques to encode information from a tokamak plasma into measurable signals; active laser based measurements, passive and active analysis of microwave-band emission, spectroscopy of plasma emission from the x-ray to infrared, characterization of neutrons produced from fusion reactions, and a wide variety of wired sensors and probes integrated into the vacuum environment. Techniques have been demonstrated by decades of government-sponsored fusion research, and CFS is looking for multidisciplinary engineers who can contribute to innovative design and engineering solutions to ensure these concepts can be integrated into the SPARC tokamak. Candidates that have design, build, or analysis skills in the mechanical, civil, or aerospace engineering disciplines are encouraged to apply. The SPARC diagnostic team welcomes engineers looking for a career transition who want to join a team with diverse backgrounds and can solve challenging problems in the growing fusion energy industry. Candidates will work alongside CFS staff, MIT-PSFC partners, and fusion community collaborators from around the world to design and build the tools that will control the SPARC plasma and measure net energy from a tokamak for the first time.

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.

What you'll do:

Support the diagnostic systems in the design and assembly of components by applying multi-disciplinary engineering and design skills to a variety of diagnostic systems

Contribute to a strong safety culture while helping to commission and operate SPARC diagnostics

Grow expertise that helps CFS build a core competency in fusion measurement tools that can deliver future tokamaks optimized for power production

Project areas can range over multiple topics including design, analysis and testing of:

Large ~5m tall structures, towers, and weldments which provide support and precision locating features for 10’s - 1000’s of kg of diagnostic equipment

Packaging and assembly constrained piping and wiring components that can interface from sensors and tokamak systems to signal processing equipment

Multi-ton radiation shielding to help increase the lifetime of sensitive equipment

Support and interfacing structures for scientific measurement tools that use a ~375m^2 dedicated laboratory space next to the SPARC tokamak

Scope and depth of required work is adjustable based on aptitude and experience but can cover:

Development of assembly and installation procedures for large assemblies

Detailed design and assembly layout in CAD for assembly tooling and structures

Rapid prototyping and design of benchtop and rackmount parts that interface custom SPARC components to COTS equipment

Collaboration with diagnosticians, other CFS teams, construction engineers, and external vendors to verify design functionality and manufacturability

Supporting the resolution of technical issues that arise during the manufacturing of SPARC diagnostic equipment

Developing and executing benchtop tests of prototypes

Providing hands on support for diagnostic assembly and calibration, providing feedback on the impact of field changes during installation

What we’re looking for:

At least a bachelor’s degree in a relevant engineering field (manufacturing, mechanical, or civil)

3+ years of relevant experience

Demonstrated record of build or design of structural assemblies requiring high strength and/or complex assembly operations

Understanding of design for manufacture principles for relevant manufacturing methods such as machining, welding, concrete fabrication, or lifting/rigging

Experience with rapid prototyping, and failure testing used to debug and improve designs

Familiarity with work planning and generation of detailed assembly instructions

Be self-motivated and exhibit excellent problem solving skills when working collaboratively

Bonus points for:

Experience with design using NX and Teamcenter for CAD and Drawings

Familiarity with design of metallic structures and weldments

Bias toward design for manufacture and experience working with vendors and fabricators to reduce cost and lead time

Design of platforms, enclosures, or support structures for medium sized, sensitive equipment

Experience with creation of piping and instrumentation diagrams

Attention to detail with an ability to pivot between topics multiple times per day

An ability to clearly express and critique ideas in a collaborative environment

Must-have Requirements:

Ability to occasionally lift up to 50 lbs

Perform activities such as typing, standing, sitting for extended periods of time

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

Willing to occasionally travel or work required nights/weekends/on-call
