Stellarator fusion reactor development with HTS magnets and advanced manufacturing
Type One Energy is building a stellarator fusion power plant using high-temperature superconducting magnets and additive manufacturing. The tech stack reveals a heavy CAD + simulation architecture (Siemens NX, Julia, Fortran, C++) paired with project management tools (Jira, Smartsheet, Microsoft Project), reflecting the complexity of multi-disciplinary fusion engineering. Hiring is 40 engineers strong across senior and intern levels, with active projects spanning reactor modeling, risk management, neutronics simulation, and digital twin development — a trajectory consistent with moving from design validation toward prototype construction.
Type One Energy commercializes stellarator fusion energy systems founded by fusion scientists and business leaders in 2019. The company pursues two main development programs — FusionDirect and Infinity — targeting a fusion power plant within the coming decade. Operations span 201–500 employees across engineering, research, and operations, headquartered in Knoxville, Tennessee, with hiring in the United States, Canada, and United Kingdom. Core technical challenges center on integrating experimental data into models, scaling manufacturing processes, neutronics modeling, tritium accounting, and coordinating multiple simulation tools across high-priority programs.
Type One Energy relies on Siemens NX for CAD, Julia and Fortran for computational physics, C++ and Python for core software, MySQL/PostgreSQL for databases, and Jira/Smartsheet for project management. They are adopting GitHub Actions and SIEM.
The company is developing two main programs: FusionDirect and Infinity2, focusing on stellarator reactor modeling, neutronics simulation, digital twin development, fuel cycle subsystem modeling, and risk management for fusion power plant commercialization.
