About the role

  • 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.

Responsibilities

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

Requirements

  • Bachelor's or Master's degree in Electrical Engineering, Embedded Systems, Power Electronics, or a related field.
  • 5+ years of experience in control and embedded development for high-power systems in R&D, industrial, or scientific environments.
  • Hands-on experience with:
  • Proficiency with simulation tools such as Simulink, MATLAB, or PLECS for modeling PSU behavior.
  • Familiarity with industrial communication protocols (e.g., UART, SPI, CAN, Modbus, OPC UA, EtherCAT).
  • Ability to occasionally lift up to 50 lbs.
  • Willingness to occasionally travel or work required nights/weekends/on-call.
  • Ability to work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, high voltage, high current, pressure systems, and cryogenics.

Nice to have

  • Experience designing control systems for fusion devices, particle accelerators, or large magnet systems
  • Knowledge of superconducting magnet characteristics, ramp-up constraints, and discharge handling
  • Integration experience with SCADA, EPICS, or plant-wide supervisory control systems
  • Familiarity with EMI/EMC mitigation techniques for control electronics in high-power environments
  • Tools & Platforms:
  • Languages: C/C++, MATLAB/Simulink, Python, Verilog/VHDL (preferred)
  • Platforms: ARM Cortex-M/A (STM32, NXP), TI DSP (C2000), Xilinx FPGAs and SoC, NI PXIe, CompactRIO (Optional)
  • Tools: STM32CubeIDE, Keil, PlatformIO, MATLAB/Simulink, LabVIEW (optional), PTP/White Rabbit for timing

Skills

  • STM32CubeIDE, Keil, PlatformIO, MATLAB/Simulink, LabVIEW (optional), PTP/White Rabbit for timing

Compensation
