GNC Engineer - Space Systems

Overview

A pioneering company in the defense and space sector is seeking a GNC Engineer to help design, develop, and deploy high-performance spacecraft systems. This is an opportunity to work on mission-critical technology across LEO, GEO, and Cislunar environments, contributing to national security and space sustainability.

You’ll own all aspects of GNC development—from early vehicle architecture to real-time operations—within a collaborative, fast-paced engineering team.

Key Responsibilities

• Lead end-to-end GNC system development, including vehicle architecture, algorithm design, software implementation, and operations

• Design and validate GNC Flight Software and hardware interfaces

• Conduct trade studies for key components: reaction wheels, torque rods, thrusters, star trackers, sun sensors, and more

• Build and refine high-fidelity 6DOF simulations and Monte Carlo analysis environments

• Use and improve control analysis tools to ensure robust performance margins

• Collaborate cross-functionally with mechanical, software, and systems engineering teams

• Support on-orbit commissioning and anomaly resolution of spacecraft

Minimum Qualifications

• B.S. in Aerospace Engineering or related discipline

• 2+ years of experience in GNC system development for space applications

• Proficiency in C++ and Python

• Knowledge of spacecraft GNC architecture, controls, orbital dynamics, and attitude determination

• Experience with closed-loop control, filtering, and state estimation

• Strong problem-solving skills and ability to work with minimal oversight

Preferred Qualifications

• M.S. in Aerospace or related discipline
• 4+ years of experience in space GNC systems design and implementation
• Experience with hardware-in-the-loop (HITL) simulations and real-time flight operations
• Hands-on experience with GNC hardware testing
• Familiarity with jitter, smear, and pointing accuracy analysis
• Must be a U.S. Citizen
• Ability to obtain or maintain a TS/SCI clearance
• Role is hybrid, with a mix of remote and required on-site work
• Some physical activity and hands-on technical work is required
