Commonwealth Fusion Systems

Company Overview

Commonwealth Fusion Systems (CFS)

Cambridge, MA, United States

2018

Approximately 430 employees (source: zoominfo.com). Revenue figures vary, with reports indicating $211.3 million or $31.7 million, though as a pre-revenue fusion developer focused on R&D, these may reflect funding or operations rather than sales.

What They Do

Commonwealth Fusion Systems (CFS) is a pioneering private fusion energy company that specializes in tokamak-based magnetic confinement fusion. Founded as a spinout from MIT's Plasma Science and Fusion Center, CFS focuses on utilizing high-temperature superconducting magnets to achieve commercial net energy production (source: cfs.energy). The company has made significant strides in its technology, particularly with the development of compact fusion machines that leverage decades of tokamak science. Their flagship projects, SPARC and ARC, aim to demonstrate net energy gain and commercial viability in the coming years (source: cfs.energy).

Projects & Track Record

CFS is currently engaged in several groundbreaking projects, most notably the construction of SPARC, which is set to be the world's first net-energy fusion machine. Located at their Fusion Energy Campus in Devens, Massachusetts, SPARC aims to demonstrate net energy gain by the late 2020s (source: cfs.energy). Additionally, CFS is planning the ARC project, a 400 MW-class grid-scale tokamak power plant designed for commercial deployment in the early 2030s. These projects are underpinned by significant technological advancements, including the successful testing of the central solenoid magnet module (CSMC) in November 2024, which confirmed the manufacturability of critical components for SPARC (source: zoominfo.com).

Recent Developments

In the past two years, CFS has made remarkable progress, including the opening of its Devens Fusion Energy Campus on February 10, 2023, which was attended by notable figures such as U.S. Secretary of Energy Jennifer Granholm (source: cfs.energy). The company has also secured substantial funding, raising $863 million in August 2024, building on a previous $1.8 billion round in May 2023, bringing total funding to over $2 billion (source: wbjournal.com). Furthermore, CFS announced its first commercial power plant site in Chesterfield County, Virginia, which will be independently financed and operated, with plans for grid connection in the early 2030s (source: zoominfo.com).

Working There

CFS offers a range of roles across various disciplines, including fusion science, engineering, manufacturing, and materials science. The majority of their workforce is based at the Devens campus, which has grown to over 430 employees (source: cfs.energy). The company culture emphasizes rapid execution and transparency, attracting top talent from the fusion and manufacturing sectors. Key executives include Co-Founder and CEO Bob Mumgaard, along with other leaders in operations and science, indicating a strong demand for expertise in tough tech and physics (source: nasdaqprivatemarket.com). While specific benefits are not detailed, the scale-up and investor backing suggest competitive packages for high-caliber roles in a mission-driven environment (source: cfs.energy). Job seekers are encouraged to monitor their careers page for openings related to SPARC and ARC advancements.

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 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 nearly $3 billion in capital, making us the largest and leading private 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 Metrology Engineer

CFS is seeking a motivated Metrology Engineer to develop, validate, and deploy inspection methods for highly engineered hardware supporting the SPARC project. In this role, you'll work hands-on with complex parts and advanced measurement systems, partnering closely with Supply Chain, Manufacturing, Design Engineering, Quality, and R&D to ensure hardware meets demanding performance and reliability requirements.

You'll thrive here if you enjoy solving ambiguous measurement problems, communicating clearly across disciplines, and building repeatable processes that scale. We're looking for someone who takes ownership-from defining inspection strategy and tooling, to documenting methods and presenting results-while continuously improving how metrology supports production and engineering teams.

The Schedule

Shift: Monday through Friday, 3:00 pm - 11:30 pm

Salary Range: $77,000 - 128,000 (includes 10% shift differential)

What you'll do

  • Develop and refine advanced mechanical inspection techniques to solve complex measurement challenges
  • Qualify and document inspection methods in partnership with Quality Engineering (procedures, work instructions, and evidence of capability)
  • Collaborate daily with Quality and Manufacturing Engineering to support production readiness and rapid issue resolution
  • Support evaluation and selection of new metrology equipment and technologies, including ROI, capability, and implementation planning
  • Maintain metrology equipment and standards; execute 5S and calibration/verification activities as applicable
  • Provide design-for-inspection input during drawing release, GD&T definition, and development of inspection standards
  • Cross-train as a Quality Technician and perform routine inspections as needed to support throughput
  • Summarize, visualize, and present critical dimensional inspection results to technical and non-technical stakeholders
  • Design and procure inspection fixturing and tooling to enable accurate, repeatable measurements

What we're looking for

  • Bachelors degree in an engineering discipline, or equivalent industry experience in lieu of a degree
  • 3-5 years of experience in a manufacturing, production, or field environment
  • Demonstrated experience developing advanced metrology/inspection techniques
  • Strong communication skills, including presenting technical information to broad audiences
  • Ability to interpret complex mechanical drawings and apply GD&T
  • Working knowledge of standard machining and fabrication processes
  • Experience programming metrology and/or manufacturing equipment
  • CAD design experience
  • CMM programming experience (ZEISS Calypso preferred)
  • Experience using portable metrology equipment (e.g., Creaform, laser tracker, CMM arm)
  • CAD design experience (Siemens NX preferred)
  • Working knowledge of quality systems fundamentals
  • Comfort using Atlassian tools (Jira, Confluence) or similar collaboration platforms

Bonus points for

  • PolyWorks Inspector experience
  • Hands-on experience with a range of metrology equipment and measurement approaches
  • Experience creating and implementing procedures, work instructions, and training materials
  • Familiarity with statistical quality tools (e.g., gage R&R, DOE)
  • Quality experience in a regulated industry (e.g., aerospace, medical)
  • Working knowledge of ERP and MES systems
  • Experience working as a field metrologist or supporting on-site measurements

Must-have requirements

  • Ability to occasionally lift up to 50 lbs
  • Perform activities such as typing, standing, or 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
  • Willingness to travel or work required nights/weekends/on-call occasionally

$70,000 - $120,000 a year
