About Thea Energy:

Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.

Position Overview:

Thea Energy is seeking a skilled and motivated Embedded Systems Engineer to lead the development of control and protection systems for high-power power supply systems deployed in the Integrated Stellarator Eos. This position focuses on enabling safe and precise operation of superconducting coil power supplies and high-voltage heating systems.

This role will involve designing and implementing embedded control systems using ARM microcontrollers, FPGAs, SoC and DSPs, as well as real-time modeling of power supply behavior. You will interface with internal system owners, power electronics vendors, and control software developers to ensure reliable and high-performance integration across the full range of mission-critical power subsystems.

Design and implement real-time control logic for HTS magnet power supplies (low-voltage/high-current) and gyrotron HVPS systems.

Develop embedded firmware for ARM-based microcontrollers (e.g., STM32, NXP), FPGA and SoC (Xilinx), DSP (TI) for low-latency control, feedback regulation, and interlock logic.

Implement quench detection and fast protection logic for superconducting magnets using embedded or FPGA-based platforms.

Simulate and validate control schemes using MATLAB/Simulink, including HIL or SIL configurations.

Program and integrate FPGA and DSP hardware as required for fast, deterministic control of power conversion systems.

Collaborate with Plasma Control and Supervisory Systems to ensure accurate interface protocols and control sequencing.

Specify and validate analog and digital I/O, high-speed communication links, and protection interfaces between PSUs and control systems.

Participate in FAT/SAT, commissioning, and system validation, including low- and high-power test operations.

Support system documentation, interface control documents (ICDs), and structured control validation plans.
