Job Description

Commonwealth Fusion Systems (CFS) is the surest path to limitless, clean fusion energy. Our mission is to enable world-wide clean energy for everyone, creating a sustainable environment for current and future generations. We have created a credible path to an operating fusion power plant in 15 years which leverages our novel collaboration with MIT and funding from strategic and financial investors who share our vision. This begins by developing a new class of high-field superconducting magnets that will enable the SPARC tokamak to demonstrate net energy from fusion for the first time. To execute this plan, we are now 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 skillsets and experience that relate to this role.
A new class of high-field superconducting magnets will enable the SPARC tokamak to demonstrate net energy from fusion for the first time. To execute this plan, we are now looking to add an Electrical Engineer to our growing team in Milpitas, CA.
This CFS Electrical Engineer will report to the Head of Superconductor R&D and will be responsible for aspects of the design, build, and implementation of the electrical and controls aspects of advanced R&D equipment and complex machinery. This equipment presents a host of challenges including large, robust, and ergonomic high-vacuum chambers; components operating under extreme conditions such as high temperatures; large temperature gradients; complicated component manipulation; large pressure differentials; tight mechanical tolerances; high uptime requirements; and numerous mechanical and electrical support systems (motors, gases, water, AC systems and controls).

This team member will:

  • Work within a multi-disciplinary and proven team of top scientists and engineers;
  • Own the specification, selection, sourcing, and implementation of key components and sub-systems such as power distribution, interlocks, sensors and actuators;
  • Specify and maintain interfaces with other engineering subsystems;
  • Report on and be accountable for project progress to the Head of Superconductor R&D;
  • Specify and write control software for advanced equipment; and
  • Implement safety systems for novel capital equipment.

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

  • 5+ years of relevant experience -- for example: design, construction, and operation of controls for industrial, large-scale equipment
  • Experience in developing and tuning control loops
  • Demonstrated ability to conceive novel solutions to challenging problems
  • Demonstrated implementation and maintenance of safety systems and procedures based on ISO 13:849 or equivalent
  • At least a bachelor’s degree in a relevant engineering field (e.g., electrical);
  • Experience in complying with Semi-S2 and Semi-S8 standards
  • Experience with fieldbus systems such as DeviceNet and Ethercat
  • AC & DC power distribution and controls
  • Cable and harness specification / sourcing
  • PLC programming experience in IEC 611:31-3 languages
  • Familiarity with Beckhoff, Allen Bradley, or closely related system
  • HMI design, implementation and maintenance with user input
  • Specification generation and suppler engagement

Additional experience and/or qualifications:

  • Interlock systems and methods that conform to Semi S2
  • Familiarly with applying ISO, NFPA, UL and other standards to design solutions
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.
At CFS, we deeply value diversity and are an equal opportunity employer by choice. We consider all qualified applicants equally for employment. We do not discriminate on the basis of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law, ordinance, or regulation.
