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 R&D Production Test Engineer
The role of a Test Engineer is to seamlessly flex between multiple disciplines and groups to effectively execute tests and projects on aggressive schedules supporting Commonwealth Fusion System’s mission. This engineer will be primarily responsible for testing and retiring risks for CFS’ HTS magnets. They must have a fundamental understanding of mechanical, electrical, materials, fluids and software engineering, or some combination thereof. This role in particular heavily emphasizes the mechanical design and construction of the test equipment. They will be responsible for the design, build, and commissioning of equipment in support of development, qualification and production test objectives. They must work collaboratively across manufacturing, R&D, procurement, and SPARC teams to achieve their test campaigns. It is also the role of the test engineer to constantly push and challenge the requirements, risks, and test objectives that they are given to help the combined stakeholders come to a consensus on why the planned test is required and what data is deemed essential for the outcome to be achieved.
What you'll do:
- Develop test plans highlighting the test objectives, key data that are needed and the instrumentation and controls necessary to obtain this data. Ensure data is reliable
- Develop test plans and processes to execute repeatable, reliable test
- Monitor and operate tests of our magnets in cryogenic, vacuum and high-current conditions
- Design, analyze, review, procure and build test equipment including structures, fluid systems, mechanical systems and electrical systems
- Understand, challenge and maintain well-documented requirements and risks for the system or component under test
- Identify and mitigate safety hazards associated with test equipment. Produce safety documentation such as job hazard assessments and test readiness reviews
- Maintain documentation, schedule and budgets for the test campaign. Documentation includes: design reviews, wiring lists, P&IDs, schematics, CAD assemblies, drawings, and operations software
- Troubleshoot and resolve integration and test discrepancies during build, commissioning and operation
- Iterate on designs, equipment and operations for repeat tests to improve test efficiency
- Perform analyses for the system predicting results and develop custom tools to analyze generated data. Compile test results clearly for review
- Lead anomaly investigations and their resolution, and present results to a team of physicists and engineers
- Execute plans for future expansion, including capital equipment and floor layouts, always having a vision for scalability of systems into a larger context. Provide visions for multi-use test infrastructure that can be scaled for multiple applications
What we’re looking for:
- Bachelor's degree in engineering or science field is required; electrical engineering, mechanical engineering or similar, or applied physics degree
- 5+ years experience designing/building/commissioning specialized test or industrial equipment, using CAD software to design complex assemblies, producing drawings for procurement, GD&T and tolerance stackups with analysis of mechanical components, strength of materials and failure criteria. Familiar with use of fasteners and analysis of welds and bolted joints
- Familiarity with electromagnetic fundamentals – voltage, current, resistance, Ohm’s Law, AC/DC, solenoids, etc.
- Excellent troubleshooting/problem-solving skills with great attention to detail
- Strong desire to improve efficiency and throughput of processes
- Effective at communicating technical topics to both technical and non-technical audiences
- High self-motivation and drive to execute quickly
- A can-do attitude and an eagerness to learn
- Collaboration skills including active listening and facilitating a productive discourse on problems
- Ability to innovate creative solutions to challenging problems
- Willingness to challenge the status quo in search of better, more efficient methods
- Experience with designing and commissioning new test facilities
- Experience with developing and executing test procedures
- Willingness to travel
- Must be willing to work required nights/weekends/on-call occasionally
Bonus points:
- Experience with structural FEA software, especially ANSYS and COMSOL
- Experience using NX and Teamcenter
- Experience with high field magnet testing traditional or superconducting
- Experience with designing fluid systems – P&IDs, component selection, ASME design codes.
- Experience with cryogenic equipment design and use for liquid nitrogen and supercritical helium use – vacuum jacketed equipment, cryocoolers, phase separators, cold traps
- Experience with high vacuum equipment design and use – roughing pumps, turbopumps, ion gauges, residual gas analyzers
- Experience with high voltage and high current power equipment design and use – power supplies, water cooled cables, insulation
Essential Requirements:
- Ability to occasionally lift up to 50 lbs
- Perform activities such as typing, stooping, standing, or sitting for extended periods of time
- Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
- #LI-Onsite
