Senior Embedded Software Engineer (Actuators & Control Systems)

Responsibilities

• Develop real-time firmware for controlling: Rocket engine valves and thrust vector control actuators (TVCAs); Satellite propulsion systems, including cold gas and electric thrusters; and Motor-driven systems such as reaction wheels, gimbals, and momentum wheels
• Implement closed-loop control for: Position, velocity, torque, and pressure regulation; as well as Feedback via encoders, LVDTs, resolvers, current sensors, and pressure sensors
• Interface with motor drivers and redundant actuator systems using protocols like CAN, SPI, UART, Ethernet, RS-422, and BISS-C.
• Design and implement safety-critical state machines for thrust sequences, valve actuation, pressurization, and safe shutdowns
• Participate in hotfire campaigns, environmental testing, and in-flight diagnostics
• Write unit-tested and reviewable production firmware for use in both testbeds and spacecraft
  
  

Minimum Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or a related field.
• 5+ years of embedded C/C++ development experience for electromechanical control systems
• Experience using oscilloscopes, logic analyzers, hardware debuggers, and source-level debuggers to troubleshoot problems at all layers of the stack.
• Experience implementing real-time control loops, motor commutation, and actuator calibration routines
• Proficiency working with servo motors, stepper motors, or brushless DC motors
• Strong understanding of low-level hardware and digital interfaces (I2C, SPI, CAN, UART)

Preferred Skills and Experience

• Prior work on rocket engine controller software, including valve sequencing and abort logic
• Experience with satellite attitude control systems (ACS), including reaction wheels, magnetorquers, and small thrusters.
• Familiarity with redundant actuator architectures and fault detection/response algorithms
• Exposure to space environment constraints such as vacuum, temperature extremes, and radiation upsets
