About the role

Axiom Space is building the world's first commercial space station. We need a GNC Engineer to design control systems for our orbital modules across the full program lifecycle. You will work in a fast-paced environment across multi-disciplinary teams, applying system-level thinking to implement robust GNC solutions.

What you will do

  • Design, analyze, and implement GNC algorithms for aerospace vehicles
  • Develop and refine control laws using classical and modern control techniques (PID, LQR, MPC, adaptive control)
  • Evaluate and integrate spacecraft control effectors (thrusters, reaction wheels, CMGs)
  • Perform 6-DOF modeling, simulation, and performance analysis under nominal and off-nominal conditions
  • Build high-fidelity dynamic models of vehicles, sensors, actuators, and environmental disturbances
  • Conduct Monte Carlo analyses, sensitivity studies, and stability assessments to validate robustness
  • Use MATLAB/Simulink, Python, C/C++ to develop simulations
  • Translate GNC algorithms into flight-ready software with numerical stability and real-time performance
  • Collaborate with embedded software teams on hardware-in-the-loop (HIL) integration and testing
  • Support development of requirements, interface definitions, and verification plans
  • Plan and execute verification and validation activities including unit tests, SIL/HIL testing, and integrated system tests
  • Analyze flight test and mission data to assess GNC performance and identify improvements
  • Support troubleshooting and root-cause analysis for anomalies during testing or operations
  • Work with hardware teams to define performance requirements and ensure GNC compatibility
  • Contribute to system-level design reviews, requirements development, and architecture decisions
  • Collaborate with propulsion, avionics, structures, and mission operations teams
  • Provide technical leadership on sub-projects, mentor junior engineers, and support design trade studies
  • Prepare technical reports, design documentation, test plans, and analysis summaries
  • Present findings at design reviews, customer meetings, and engineering forums
  • Ensure compliance with aerospace standards, safety requirements, and certification processes
  • Communicate project progress, status, and issues to stakeholders and leadership
  • Implement and maintain agile project management methodologies

Your background

  • Bachelor's degree in Aerospace Engineering or related technical discipline
  • 2-4 years of experience developing attitude control systems on flight vehicles (spacecraft preferred)
  • Experience in at least one of: control law development and stability analysis, momentum exchange actuators (Reaction Wheels, CMGs), control systems for flexible-mode or articulating vehicles, optimization techniques (least squares, linear/quadratic programming), SWIL and HWIL testing, actuator testing and characterization
  • Experience with 6-DOF Monte Carlo simulations; NASA Trick simulation framework and JSC Engineering Orbital Mechanics (JEOD) preferred
  • Proficient with C++, MATLAB, and/or Python
  • Track record of delivering outcomes in ambiguous, fast-moving environments
  • Proven ability to deliver high-quality results under tight deadlines

What we value

  • Passion for space and mission
  • Entrepreneurial, growth mindset
  • Perseverance and resourcefulness
  • Precision execution with pace
  • High emotional intelligence and cross-functional collaboration
  • Excellent written and verbal communication
  • Accountability, extreme ownership, and sense of urgency

Requirements

  • Must be able to complete a U.S. government background investigation
  • Proof of U.S. Citizenship or U.S. Permanent Residency required
  • Must be willing to work evenings and weekends as needed to meet critical project milestones

Work environment

Onsite at our Space Station Development Facility (SSDF) in Houston. Generally office-based but may involve inside or outside work depending on task. Work involves sitting or standing for extended periods (90% of the time). May require lifting and carrying up to 25 lbs. (5% of the time). Standard office equipment (PC, phone, printer, etc.).
