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 Senior Mechanical Engineer - HTS Magnet Feeder System
As a Senior Mechanical Engineer for the SPARC superconducting magnets feeder team (FEED), you will own hardware from early concepts to SPARC delivery, performing thermal, structural, and electromagnetic analysis using hand calculations and finite element methods. You will develop design notes, technical specifications, assembly procedures and documentation necessary to manufacture and install the SPARC FEED hardware and supporting systems. In your role you will also support procurement in the preparation and execution of manufacturing contracts.
What you'll do:
- Act autonomously as the primary owner of SPARC and ARC current feeder (FEED) hardware, ensuring designs are completed, validated, procured, built, and installed correctly and on time
- Produce new and iterate on existing design concepts, using a deep understanding of physics, structural mechanics, and analysis techniques for both metallics and composites
- Liaise with partner teams such as R&D, analysis, manufacturing, and procurement to drive completion of program milestones in a timely fashion
- Diagnose issues on the production and assembly line and provide path forward based on known understanding of hardware
- Prepare reports, presentations, and other documentation to serve as design documentation and validation of final SPARC and ARC FEED systems
What we’re looking for:
- A minimum of 5 years of engineering design and analysis experience is required, including at least 2 years providing engineering support to production hardware in the form of resolving technical issues and implementing design for manufacturing changes
- Excellent fundamental knowledge of mechanical systems such as static structures and heat transfer
- Relevant hands-on experience in the form of parts designed for high loads and extreme environments
- Bachelor’s degree in mechanical engineering, aerospace engineering, physics, or another relevant field
- Demonstrated record of design of mechanical components beyond desktop scale. E.g. high power (MW+), high mass (ton+), high force (MN+)
- Familiarity with all steps in the design process with an emphasis on creativity, simplicity, and execution
- Be self-motivated, committed to self-growth, and exhibit excellent problem-solving skills
Bonus points:
- Hands on experience developing and executing testing to buy down technical risk in new hardware development
- Experience with vacuum, cryogenics, nuclear irradiation, superconductivity, electromagnetics
- Authored documentation in the form of specifications to drive requirements to manufacturing and assembly.
- Led interdisciplinary teams to deliver hardware on time and to requirements
- Experience with NX, ANSYS, and COMSOL
Essential Requirements:
- Perform activities such as 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
