HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. Our mission is to deploy these power plants to meet global decarbonization goals as fast as possible. To that end, 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 implement this plan, we are looking to add dedicated people to the team who treat people well, improve our work by adding multifaceted perspectives and new ways of solving problems, have achieved outstanding results through a range of pursuits, and have skills and experience related to this role.\nThe Senior Electronics Engineer will be responsible 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 Instrumentation, Diagnostics, 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 – and will support installation and commissioning of their hardware in the field either directly or by generating documentation packages.\nThis team member will:\nDesign signal conditioning electronics, sensor interfaces, and data acquisition hardware for various instrumentation systems within the SPARC tokamak and plant\nDesign high-density signal routing electronics for in-tokamak and external plant control system applications\nCollaborate with instrumentation and control engineers for and other key stakeholders to ensure all necessary functions and interfaces are included in the design and implemented according to requirements\nCoordinate and oversee implementation, testing, installation and commissioning of custom I&C electronics according to the project schedule\nManage suppliers of components and integrated subsystems of I&C electronics\nProduce engineering deliverables such as circuit diagrams, schematics, PCB layout and routing, electronics assembly files\nEnsure the design is completed in compliance with the Code of Record and established requirements\nMaintain interfaces with other engineering subsystems\nReport 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\nThe ideal candidate will have most, if not all, of these requirements:\nBachelor’s Electrical Engineering\nDirect experience in the design and procurement of custom electronic assemblies from concept to completion\nDirect experience generating electrical schematics and analyzing circuit performance\nProficiency integrating and troubleshooting analog and digital circuits\nProficiency with EDA software, including schematic capture and PCB layout and routing, particularly Altium\nProficiency with circuit simulation software, e.g. SPICE or equivalent\nAdditional preferred experience and/or qualifications:\nExperience in the design and procurement of custom electronic assemblies from concept to completion under a QA program\nExperience with the design of low-power supplies and precision analog electronics\nExperience designing electronics in support of various on-board and off-board communication protocols, such as Ethernet, RS422, SPI, I2C, CAN\nUnderstanding of the development of custom embedded systems, including controller / processor selection and firmware development\nExperience with the design of RF electronics up to 200 MHz\nExperience designing high-reliability electronics in an industrial setting\nElectronics design for extreme environments, including cryogenic temperature and ionizing radiation\nWork in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics\nCFS team members thrive in a fast-paced, dynamic environment and have demonstrated exceptional results through a range of different pursuits.
