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 we're working with policymakers, suppliers, and many others to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading 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 an R&D 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 emphasizes electrical power systems used to test HTS magnets. They will be responsible for the design, analysis, build, commissioning and maintenance of high current and high voltage electrical equipment. 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:

Design, analyze, review, procure and build test equipment for energizing superconducting magnets

Contribute to ground-up design of electrical testing infrastructure in new testing facilities

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

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 electrical apparatus or equipment

2+ years using electrical analysis software such as PLECS, LTSPICE, ETAP, Simulink or similar

Aptitude for applying electromagnetic fundamentals to understand system behavior, such as: parasitic inductance/capacitance, EMI coupling, dielectric breakdown, etc

Familiarity with electrical standards such as building codes (NEC/NFPA 70), personnel safety (OSHA, NFPA 70E), equipment safety standards (IEC, IEEE, etc)

Experience working with high-power electronics, such as rectifiers, DC/DC converters, inverters, etc

Experience working with stored energy devices such as batteries and supercapacitors

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

Bonus points for:

Experience with thermal or electromagnetic FEA software.

Experience using NX and Teamcenter to manage CAD assemblies

Experience with schematic or PCB design software such as AutoCAD, SkyCAD, Altium, etc

Experience with high field magnet testing traditional or superconducting

Must-have requirements:

Ability to occasionally lift up to 50 lbs

Perform activities such as stooping, climbing, typing, 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

Willingness to travel or work required nights/weekends/on-call occasionally

#LI-Onsite

At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.
