R&D Test Engineer - Power Systems

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 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 electromechanical design of power systems within the magnet test facility. 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:

• Own and retire technical risks by designing, analyzing, procuring, building, and commissioning test equipment utilizing your knowledge of physics, structures, instrumentation and controls, mechanical and electrical systems
• Mechanical design and build of specialized electrical equipment to support magnet testing
• Develop test plans that effectively retire technical risks. Plans include appropriate instrumentation and controls necessary to obtain repeatable and reliable data
• Understand, challenge and maintain well-documented requirements and risks for the system or component under test. Documentation includes: design reviews, wiring lists, P&IDs, schematics, CAD assemblies, drawings, and operations software
• Identify and mitigate safety hazards associated with test equipment and test plans
• Design safety into the system and produce safety documentation such as job hazard assessments and test readiness reviews
• Design experiment campaigns that match our fast pace and work hard to maintain the proposed schedule
• Troubleshoot and resolve integration and test discrepancies during build, commissioning and operation
• Support end users with troubleshooting and upgrades once the test stand is handed over
• Iterate on designs, equipment and operations for repeat tests to improve test efficiency
• Create physics/mechanical models to predict results. Develop custom tools to analyze generated data.
• Compile test results clearly for review
• Lead anomaly investigations and their resolution (root cause analysis), 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; mechanical engineering, electrical engineering or similar applied physics degree
• 5+ years experience designing/building/commissioning electrical equipment with hands on experience and a proven ability to deliver reliable data
• 5+ years using CAD software (NX is a plus) to design complex assemblies, producing drawings for procurement, GD&T and tolerance stack-ups
• 5+ years experience with analysis of mechanical components (Finite Element Analysis), strength of materials and failure criteria
• Excellent troubleshooting/problem-solving skills with an ability to innovate creative solutions to challenging problems
• The ability to effectively communicate technical topics to both technical and non-technical audiences.
• The ability to challenge requirements and defend results when needed, as well as the ability to acce
