Staff GNC Engineer

YOUR MISSION

RESPONSIBILITIES

• Design, develop, and validate GNC algorithms and systems for spacecraft operating in LEO, GEO, and Cislunar environments.
• Develop and refine orbit determination and trajectory planning algorithms for a range of mission profiles, including interplanetary and cislunar operations.
• Lead the design, development, and integration of spacecraft attitude control systems, including sensor and actuator selection, modeling, and testing.
• Perform detailed simulations and analyses of spacecraft guidance, navigation, and control performance using tools such as MATLAB, or equivalent software.
• Optimize GNC strategies for mission-specific constraints, such as fuel efficiency, precision targeting, and operational robustness.
• Define and oversee GNC system validation campaigns, including hardware-in-the-loop (HIL) testing, simulation validation, and on-orbit performance evaluation.
• Collaborate with subsystem teams, including propulsion, avionics, and mission operations, to ensure seamless integration of GNC systems.
• Support mission operations with orbit maintenance, trajectory adjustments, and anomaly resolution. 

QUALIFICATIONS

• 12 years of experience in spacecraft GNC system design, analysis, and operations.
• Proficiency in orbit determination techniques for LEO, GEO, and Cislunar environments, including Kalman filtering and batch least squares methods.
• Strong understanding of spacecraft attitude dynamics and control systems, including quaternion-based kinematics.
• Experience with GNC simulation and modeling tools such as MATLAB/Simulink, STK, GMAT, or equivalent.
• Experience coding in Python and C .
• Hands-on experience with flight hardware, including star trackers, reaction wheels, IMUs, and thrusters.
• Proven ability to deliver GNC solutions for challenging mission profiles in a fast-paced environment. 
• Ability to maintain or obtain TS//SCI clearance.

PREFERRED SKILLS AND EXPERIENCE

• Expertise in orbit determination and trajectory design for cislunar or interplanetary missions.
• Familiarity with mission-specific challenges, such as lunar gravity assists, libration point orbits, and deep-space navigation.
• Experience with optimization techniques for trajectory planning, such as genetic algorithms or direct collocation methods.
• Hands-on experience with autonomous navigation techniques, such as optical navigation or onboard astrodynamics.
• Familiarity with advanced sensor fusion techniques and their application in challenging environments, such as cislunar space.
• Experience working in a startup or similarly fast-paced and multidisciplinary environment. 

COMPENSATION

• Base Salary:  $180,000 - $235,000

• Equity Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave 

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, location, and experience. 

ADDITIONAL REQUIREMENTS
