About the role
- Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly.
- We are seeking a Principal Spacecraft Guidance, Navigation & Control Engineer to serve as the technical authority for the GNC subsystem across multiple spacecraft programs, leading architecture, design, procurement, integration, and verification.
Responsibilities
- Join us in building the next generation of spacecraft.
- Ownership - Build and validate the GNC capability that defines how our spacecraft maneuver, point, and operate autonomously.
- Growth - Collaborate across avionics, FSW, systems, and mission ops, with opportunities to expand into dynamics modeling, autonomy, or flight operations.
- Own the end-to-end GNC/ACS architecture from concept development through flight operations.
- Own GNC subsystem level requirements.
- Lead spacecraft attitude and control system design, including actuator sizing, sensor selection, control authority, and momentum management strategy.
- Define and implement control laws for high-ΔV maneuvering, precision pointing, station-keeping, and proximity operations.
- Develop and maintain high-fidelity 6DOF spacecraft simulation environments for analysis, trade studies, verification, and anomaly resolution.
- Lead GNC participation in system-level reviews (MCR, SRR, PDR, CDR, TRR) and serve as the primary technical voice for the discipline.
- Analyze flight telemetry and test data to assess performance, diagnose anomalies, and drive configuration or algorithm updates.
Requirements
- To comply with U.S. Government space technology export regulations, including ITAR, applicants must be a U.S. citizen, lawful permanent resident, protected individual under 8 U.S.C. §1324b(a)(3), or otherwise eligible to obtain the required authorizations from the U.S. Department of State.
- Support early-orbit operations and critical mission phases as required.
- 15+ years of experience in spacecraft GNC/ACS development, including full lifecycle flight programs.
- Strong experience with thruster-based ACS architectures and propulsion-coupled control systems.
Compensation
- $175,000 - $225,000
- The salary range for this role is determined based on a variety of factors including work experience, education, technical expertise, certifications, critical skills, and business considerations.
- Highly competitive equity grants are included in the majority of full-time offers and are considered part of Quantum Space's total compensation package.
Benefits
- Compensation - Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity participation.
- Support propulsion-coupled dynamics modeling, including thrust misalignment, slosh effects, and flexible-body considerations as needed.
