Diagnostics Mechanical Engineer

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.

What you'll do:

• Shepherd SPARC diagnostic sub-systems through design closeout, test, and procurement, working with a team of scientists, designers, analysts and engineers
• Integrate technical input from experts on the team to ensure diagnostic designs will survive SPARC’s harsh environments and be usable to achieve SPARC’s scientific mission goals
• Coordinate with manufacturing engineers to align on build and test strategy for complex integrated systems, and support builds in the field to maintain quality and speed
• Contribute to a strong safety culture

What we're looking for:

• Bachelor’s degree in a relevant engineering field (mechanical, aerospace, civil or nuclear)
• 5+ years of relevant experience designing and delivering mechanical systems
• Demonstrated examples of delivering cradle-to-grave mechanical design with nuanced environmental or performance requirements
• Experience designing for manufacturing and assembly, and collaborating with partners to oversee or carry out integrated builds
• Bias toward action, and a balance of engineering intuition and technical rigor that allows for robust, simple designs to be generated with speed
• First principles based approach to engineering and ability to understand concepts and tradeoffs that bridge engineering and physics
• Strong communication skills to gather inputs and distribute information across several partner teams

Bonus points for:

• Experience with Siemens NX, Teamcenter, or Ansys as CAD, PLM, and analysis tools
• Experience with software development, particularly in Python
• Experience designing large equipment requiring lifting/rigging tools to assemble
• Experience with design of systems for exposure to high stress, UHV, high temperature, high magnetic field, and/or radiation environments

Must-have requirements:

• Ability to occasionally lift up to 50 lbs
• Perform activities such as climbing, typing, standing, or sitting for extended periods of time
• Willingness to travel or work required nights/weekends/on-call occasionally
• 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
