Commonwealth Fusion Systems

Company Overview

Name

Commonwealth Fusion Systems (CFS)

Headquarters

Cambridge, MA, United States

Founded

2018

Size

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.

Job Description

Commonwealth Fusion Systems (CFS) is seeking a Staff Quality Engineer to serve as the subject matter expert (SME) for dimensional management and quality strategy for our HTS Magnet production and the SPARC Project. In this high-impact role, you will be the technical authority on Geometric Dimensioning and Tolerancing (GD&T), ensuring that novel, first-of-a-kind designs are translated into manufacturable and verifiable hardware.

In this capacity, you will act as the technical authority for translating novel, first-of-a-kind design requirements into manufacturable reality. You will partner closely with Engineering to understand design intent and work to better define GD&T requirements that are more manufacturable, while architecting the inspection systems, tooling, and process controls necessary for HTS Magnet production. Serving as the subject matter expert in GD&T, you will resolve complex fabrication challenges with risk-informed quality strategies that directly enable the SPARC project mission.

What you'll do

  • Manufacturing-Driven GD&T Interpretation
    • Partner closely with Engineering to understand design intent and define more manufacturable GD&T requirements; work directly with Manufacturing Engineers to determine how to achieve critical tolerances using existing equipment and novel fabrication methods
  • Proactive Problem Solving
    • Lead the development of risk-informed QA controls that bridge the gap between design intent and shop-floor reality to positively impact the CFS mission
  • Inspection Architecture
    • Architect measurement systems and quality inspection methods specifically designed for the assembly of large metallic components, moving beyond theoretical models to executable floor-level plans
  • Disposition Leadership
    • Provide risk-informed leadership to design engineers in dispositioning Non-Conformance Reports (NCRs) across the full range of outcomes (use-as-is, rework, repair, scrap), grounded in structural integrity and functional requirements
  • Process Stabilization
    • Regularly analyze manufacturing data using control charts and process capability studies to identify emerging process drift, escalating insights to Operations to drive immediate process adjustments
  • Sub-system Integration
    • Facilitate the creation and execution of PFMEAs and Quality Plans for the installation of sub-systems, ensuring that assembly tolerances are managed as the SPARC project scales
  • Measurement System Analysis (MSA)
    • Lead advanced MSA and Gage R&R studies to ensure that the methods used to measure novel designs are statistically sound and repeatable in a production environment
  • Mentorship & Oversight
    • Provide technical coaching to QC Inspectors and Quality Engineers, specifically regarding GD&T interpretation on the shop floor

What we're looking for

  • BS in Mechanical, Industrial, Material Science or Manufacturing Engineering
  • Minimum 10+ years of Quality Engineering experience in a manufacturing, assembly or equipment manufacturing environment, specifically focused on transitioning new products to production
  • Demonstrated program-level ownership of dimensional management or quality strategy, not solely execution of inspection plans defined by others
  • Proven experience architecting inspection systems and measurement strategies for complex hardware, including defining what to measure, how, and to what acceptance criteria
  • GD&T Expertise: Mastery of GD&T (ASME Y14.5) with a proven ability to translate theoretical tolerances into practical manufacturing work instructions
  • Metrology: Deep knowledge of CMM, Romer Arm, and Laser tracker applied to complex geometries
  • ISO 9001-2015, Six Sigma, Statistical Process Control (SPC), Process Capability Analysis, PFMEA, Measurement System Analysis (MSA), APQP
  • GD&T and Metrology (Required)
  • Knowledge of NDE (non-destructive evaluation) methods including dye penetrant, ultrasonic, eddy current, and x-ray (Preferred)
  • Knowledge of cryogenics (Preferred)
  • Minitab or JMP, MS Excel (including VBA), MS Visio
  • Excellent communication and organization skills

Bonus points for

  • Manufacturing Experience: NPI in a low volume environment
  • Mentorship & Oversight: Proven ability to provide technical coaching and indirect leadership to QC inspectors and quality engineering teams
  • Statistical Tools: Proficiency in Minitab or JMP for conducting Process Capability Analysis and Six Sigma methodologies

Must-have Requirements

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

$130,000 - $200,000 a year
