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.
As a Mechanical Engineer for the SPARC superconducting magnets, you will perform 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 superconducting magnets and their embedded and supporting systems. In your role you will also support procurement in the preparation and execution of manufacturing contracts.
This team member will:
- Produce new and iterate on existing design concepts using NX, using a deep understanding of physics and structural mechanics for both metallics and composites
- Identify enabling technologies in the modeling and construction of high-temperature superconducting magnets
- Perform thermal, fluid, structural, and electromagnetic analysis of SPARC magnets, including conductors, insulation, joints, supports, fluid manifolds, insulator breaks, and inform design decisions
- Perform proof of principle and hand calculations as necessary to confirm the validity of the analysis
- Work with experimental teams on instrumentation, measurement, and correlation of experiment to analysis
- Provide technical support to procurement during manufacturing
- Develop assembly and commissioning documentation
- Support the development of the tooling for assembly
- Support the resolution of technical issues that arise during the manufacturing, assembly and commissioning
- Prepare reports and presentations as requested
- Review other analysts work when requested
The ideal candidate will have most, if not all, of these requirements:
- Bachelor’s degree in mechanical engineering, aerospace engineering, physics, or another relevant field
- At least 5 years of engineering design and analysis experience
- Solid background in component design and performing FEA analyses
- 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 and simplicity
- Be self-motivated and exhibit excellent problem-solving skills
Additional experience and/or qualifications:
- Experience with NX, ANSYS, and COMSOL
- Experience with vacuum, cryogenics, nuclear irradiation, superconductivity, electromagnetics
- Hands-on experience developing hardware
- 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
