Type One Energy Tech Stack

Stellarator fusion power plant developer using superconducting magnet technology

Renewable Energy Power Generation Knoxville, Tennessee 201–500 employees Founded 2019 Privately Held

Type One Energy is developing a stellarator-based fusion power plant, and its stack reads like a national lab with a hardware shop attached: ANSYS, COMSOL, OpenFOAM and HFSS for multiphysics simulation, Fortran and Julia for computational physics, and FPGA, VHDL, PetaLinux and RTOS for real-time diagnostics control. Hiring is overwhelmingly senior engineering, though overall velocity is slowing.
