About the role

El Segundo, CA
Full Time
Job Description: As Senior GNC & Mission Design Engineer, you will design and control missions with the most performant multi-mode propulsion system ever built onboard General Galactic spacecraft and missions.

Responsibilities

• Build practical analytical tools, simulations, spreadsheets, and Python/MATLAB models to evaluate mission feasibility, requirements, timelines, etc.
• Own GNC analyses, algorithms, simulations, and operating modes for General Galactic spacecraft and missions.
• Support business development by rapidly assessing customer mission concepts, producing credible mission architectures, evaluating technical feasibility, and generating proposal-ready performance estimates.
• Collaborate with flight software engineers to integrate GNC algorithms.
• Conduct Monte Carlo analysis and robustness analysis for mission plans and GNC algorithms.
• Review flight data, test data, and simulation results to identify anomalies, validate models, and improve vehicle and mission performance.
• Own attitude determination and control (ADCS) development and make vs buy trades.
• Conduct mission/trajectory design and maneuver planning, including ΔV budgeting and mission conops.

Requirements

• BS in aerospace engineering, controls engineering, or a related technical field
• 4+ years of experience in GNC, mission design, flight dynamics, astrodynamics, controls, etc
• Experience with Python, MATLAB, Simulink, STK/ODTK/GMAT, FreeFlyer, Basilisk, Monte Carlo frameworks, or similar environments
• Experience in a fast-paced startup environment or similar
• High agency, strong ownership, and willingness to work hands-on across disciplines
• A first-principles approach to problem solving even with incomplete or partial information
• Strong fundamentals in orbital mechanics, dynamics, state estimation, controls, propulsion-enabled maneuvering, and mission analysis

Benefits

Includes medical/vision/dental/PTO/401k/stock options, and more!
