Principal Embedded Software Engineer Actuators & Control Systems

Department: Software Employment Type: Full Time Location: Redondo Beach Compensation: $180,000 - $260,000/year

Description As a Senior Embedded Software Engineer at Impulse focused on Actuation & Control Systems, you will be responsible for developing embedded software that controls a variety of actuated systems across launch vehicles and spacecraft. These include rocket engine valves, satellite thrusters, thrust vector control actuators, and motor-driven devices such as reaction wheels and gimbals. You will collaborate with propulsion, avionics, and GNC teams to design high-performance, fault-tolerant firmware capable of operating reliably in harsh environments such as launch and space.

Responsibilities

• Develop real-time firmware for controlling Rocket engine valves and thrust vector control actuators (TVCA).
• Develop Satellite propulsion systems including cold gas and electric thrusters.
• Develop Motor-driven systems such as reaction wheels, gimbals, and momentum wheels.
• Implement closed-loop control for position, velocity, torque, and pressure regulation.
• Implement 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

• Bachelors degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or a related field.
• 12 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.
