Mechanical Engineer - Power Electronics job in Devens at Commonwealth Fusion Systems

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.
CFS is collaborating with MIT to leverage decades of research combined with new groundbreaking high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. The mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. To execute this plan, we are looking to add talented people to the team who are mission-driven and treat people well, improve our team by adding diverse perspectives and new ways of solving problems, have demonstrated exceptional results through a range of different pursuits, and have skill sets and experience that relate to this role.
The SPARC tokamak will have a large pulsed power system to operate the superconducting magnets, requiring ~300 megawatts of power at a few kilovolts and tens of kiloamps for up to 30 seconds. We're looking for an early-/mid-career mechanical engineer with experience or interest in large-scale power supplies and to help with the design, procurement, commissioning, and operation of our magnet power supplies RF systems.

This team member will:

• Work within a multi-disciplinary team of engineers and physicists to outline the design and specification of the SPARC magnet power supplies
• Assist simulation and modeling efforts to help evaluate system requirements and support operational goals
• Interface with vendors to ensure that they can deliver power supplies that meet SPARC requirements
• Participate in the planning for commissioning and integration of the SPARC Pulsed Power Electrical System
• Attend and participate in meetings where design progress is discussed, iterated, and updated

The ideal candidate will have most, if not all, of these requirements:

• BSEE or BSME
• Position is entry level
• Experience with power systems of at least the class: ~1 kV, ~10 kA, ~10 s (e.g., thyristor rectifiers used as power supplies for smelters, electromagnets, electrochemical processing, traction, etc.)
• Familiarity in applying IEEE standards to design solutions
• Familiarity with computer-based analysis of electrical systems
• A professional engineer license is preferred, but not required
• Experience with industry standard electrical design tools
• An ability to clearly express and critique ideas
• An emphasis on elegance and simplicity over complexity
• A drive towards commercially viable solutions

Additional preferred experience and/or qualifications:

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

CFS team members thrive in a fast-paced, dynamic environment and have demonstrated exceptional results through a range of different pursuits. We all tightly align with our company values of integrity, execution, impact and self-critique. As we grow, we are looking to add talented people who are mission driven and bring diverse perspectives and new ways of solving problems.
