About the Role

You will design and develop motor controls, automation sequences, and embedded control systems for the vehicle's fluid systems. This includes motor-driven valve and pump actuation, automated fill/drain/vent/conditioning sequences, and closed-loop control of fluid subsystems across propulsion, pressurization, and thermal management. You will work at the intersection of electrical, mechanical, and software engineering to deliver robust, flight-ready control solutions from concept through integration and operations. This role is located in Seattle, WA.

Responsibilities

  • Design and implement motor control systems for electrically actuated valves and pumps, interfacing with drive electronics, feedback sensing, and control algorithms.
  • Develop automated sequences for propellant fill, drain, vent, and conditioning operations on both vehicle and ground support equipment.
  • Architect and implement closed-loop control for fluid system parameters (pressure, temperature, flow rate, liquid level) across propulsion and thermal subsystems.
  • Select and integrate actuators, motors, encoders, position sensors, and pressure/temperature instrumentation for fluid system control.
  • Design control electronics hardware (motor drivers, power stages, sensor interfaces) or define requirements for electrical engineering partners.
  • Develop embedded firmware and real-time control software for fluid system controllers and sequencers.
  • Perform system modeling and simulation to validate control strategies, predict transient behavior, and tune controller gains.
  • Define and execute hardware-in-the-loop (HIL) and system-level test campaigns to verify control performance and fault response.
  • Develop fault detection, isolation, and recovery (FDIR) logic for fluid system automation to ensure safe operations during nominal and off-nominal conditions.
  • Work closely with fluid systems, propulsion, avionics, and software teams to integrate controls into the broader vehicle architecture.
  • Support propulsion hot-fire testing, vehicle fill/drain operations, and ground system commissioning.
  • Investigate anomalies, analyze telemetry data, and iterate on control designs to improve performance and reliability.

Basic Qualifications

  • Bachelor's degree in Mechatronics, Electrical, Mechanical, Aerospace, or related engineering field.
  • 3+ years of experience in controls engineering, mechatronics, or automation for hardware systems.
  • Experience with motor control (BLDC, stepper, or brushed) including drive electronics and feedback control.
  • Experience with PID control loops, Kalman filtering, feedforward control or other control loops and estimation algorithms.
  • Proficiency in embedded programming (C/C++) for real-time control applications.
  • Experience developing automated sequences or state machines for complex physical systems.
  • Hands-on experience integrating sensors, actuators, and control electronics into hardware assemblies.

Preferred Qualifications

  • Experience with PLC/PAC programming or custom sequencing engines for ground support equipment.
  • Knowledge of control system design tools (MATLAB/Simulink, Python, LabVIEW, or equivalent) for modeling and simulation.
  • Experience designing or specifying motor drives and power electronics for harsh environments (vibration, thermal extremes).
  • Familiarity with communication protocols common in aerospace (CAN, RS-422, EtherCAT, SpaceWire).
  • Experience with hardware-in-the-loop testing and rapid prototyping of control systems.
  • Understanding of fluid system physics (pressure regulation, two-phase flow, thermal transients) as it relates to control design.
  • Experience with launch vehicle, spacecraft, or rocket engine fluid system controls.
  • Familiarity with cryogenic fluid handling and the controls challenges of cryogenic environments.

Compensation and Benefits

  • Salary: $160,000-$200,000 annually
  • Equity in Cowboy Space Corp.
  • Medical, dental, and vision insurance
  • 401(k) retirement savings plan
  • Paid time off and 10 paid holidays per calendar year
  • Paid parental leave
  • Relocation assistance if applicable
  • Daily lunch in the office and fully stocked kitchen
