Requirements

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

What the job involves

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
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
