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 Electronics Engineer

Take responsibility for the design, sourcing, implementation, testing, installation, and commissioning of custom electronics required for various I&C systems throughout the SPARC tokamak and plant. This individual will translate requirements from Power, RF, and Controls Engineers into practical, reliable electronic designs and assemblies which interface both with field and infrastructure hardware. This individual will own their designs from concept development, through detailed design and simulation, generating fabrication and assembly files – or contracting out design deliverables as necessary –, define and perform qualification testing, and will support installation and commissioning of their hardware in the field either directly or by generating documentation packages. Position level can scale with experience.

What you'll do:

• Design high-power power convertor electronics for SPARC tokamak magnets and RF heating system
• Design high-density signal routing electronics for in-tokamak and external plant control system applications
• Collaborate with instrumentation and control engineers and other key stakeholders to ensure all necessary functions and interfaces are included in the design and implemented according to requirements
• Coordinate and oversee implementation, testing, installation and commissioning of custom I&C electronics according to the project schedule
• Manage suppliers of components and integrated subsystems of I&C electronics
• Produce engineering deliverables such as circuit diagrams, schematics, PCB layout and routing, electronics assembly files
• Ensure the design is completed in compliance with the Code of Record and established requirements
• Maintain interfaces with other engineering subsystems
• Report on and be accountable for progress to the head of I&C and the engineer responsible for the systems for which the I&C is being produced

What we’re looking for:

• Bachelor’s Electrical Engineering
• Direct experience in the design and procurement of custom electronic assemblies from concept to completion
• Direct experience generating electrical schematics and analyzing circuit performance
• Proficiency integrating and troubleshooting analog and digital circuits
• Proficiency with circuit simulation software, e.g. SPICE or equivalent

Bonus points for:

• Proficiency with EDA software, including schematic capture and PCB layout and routing, particularly Altium
• Direct experience in the design and procurement of custom electronic assemblies from concept to completion
• Design of high-power power supplies (100+ A)
• Design of RF electronics up to 200 MHz
• Experience in the design and procurement of custom electronic assemblies from concept to completion under a QA program
• Designing electronics in support of various on-board and off-board communication protocols, such as Ethernet, RS422, SPI, I2C, CAN
• Development of custom embedded systems, including controller / processor selection and firmware development
• Designing high-reliability electronics in an industrial setting
• Electronics design for extreme environments, including cryogenic temperature and ionizing radiation
• Altium

Must-have requirements:

• Perform activities such as typing, standing, or sitting for extended periods of time
• 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
