Tritium Systems Engineer

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 tritium engineer will work closely with the SPARC fueling and tritium SRO, technical leads, and tritium experts to test, design, procure, and operate tritium processing systems for the SPARC fuel cycle. These systems include separation of tritium from other hydrogenics and tokamak gases, instrumentation and measurement, storage, and interfacing with other fueling and tokamak systems. This engineer will design and specify the requirements for the tritium storage, monitoring and separation systems, conduct hands-on lab work for validating the design, and develop integrated tritium systems for the SPARC fuel team. They may also support early design for the fueling systems on the ARC tokamak, a deuterium-tritium pilot power plant. The fueling systems engineer will collaborate with an interdisciplinary team of engineers, builders, scientists, vendors, and supply integration managers, and report to the Fueling and Tritium System Responsible Officer. 

Applicants must have hands-on experience with tritium and/or vacuum-grade systems. Additionally, experience prototyping systems, familiarity with gas instrumentation and diagnostics, design for vacuum, and systems integration are welcome. This job may require periodic travel for off-site testing at collaborative facilities, supplier development, and meetings with tritium researchers.

This team member will:

- Lead the design of components and test systems for use within the SPARC fueling system including but not limited to tritium storage and delivery, tritium monitoring systems, isotope separation, cryopumps, and interfacing systems.
- Create testing methods and coordinate in-house testing or supplier testing of components to meet SPARC requirements
- Develop processes and layouts for fueling subsystems that are communicated through standard engineering documents and integrated with tokamak and tokamak interfacing systems
- Support the fueling system technical leads in completion of design and documentation for engineering design reviews
- Coordinate engineering system development with contractors and integrate systems in house for SPARC operations
- Provide tritium experience and expertise for development of SPARC and ARC operations.
- Ensure all systems that will contact or contain tritium are compatible with tritium; maintain compliance with tritium licenses

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

- Master’s degree or similar experience in mechanical engineering, chemical engineering, physical chemistry, applied physics
- +3 years experience building vacuum systems and knowledge of measurement techniques 
- +3 years experience with design of tritium systems
- Knowledge of transport phenomena and chemical processes in gasses and interaction of volatile gasses with seals, pumps, transfer lines, etc.;
- Laboratory experience handling hazardous materials
- Knowledge of hydrogen surface chemistry
- Experience in hydrogen separation and measurement methods
- An exceptional track record of safety and attention to detail
- Data acquisition and test stand automation experience
- High-vacuum systems experience
- High-pressure gas delivery systems experience
- Analytical instrumentation experience
- Process engineering and systems integration experience
- Interface management experience
- Change control experience

Additional experience and/or qualifications:

- Use of engineering management tools
- Confluence/JIRA and remote collaboration tools
- Experience developing automated testing platforms
- Integration of tritium systems into facilities
- Knowledge of tritium licensing and regulations
- Ability to lift up to 50 lbs occasionally
- Ability to type, sit, and stand for extended periods of time
- Withstand exposure to heat, cold, noise, hazardous gas and radiological hazards
- Willingness to occasionally travel to vendor / development partners
- Equipment installation and commissioning activities may require evening / weekend work shifts

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.
