The Role
Develop real-time, fault-tolerant embedded firmware to control rocket and satellite actuators and motor-driven devices. Implement closed-loop control, interface with various sensors and communication protocols, design safety-critical state machines, support testing and hotfire campaigns, and produce unit-tested production firmware for spacecraft and testbeds.
Summary Generated by Built In
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 (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
