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.

Who We're Looking For

We are seeking an experienced and technically driven Software Systems Engineer III to manage the development of spacecraft software architectures, mission operations capabilities, and system-level engineering solutions for next-generation spacecraft. In this role, you will bridge software engineering and systems engineering disciplines, driving technical solutions from early concept development through spacecraft integration, mission execution, and on-orbit operations.

You will serve as a senior technical contributor responsible for software architecture, systems engineering, interface definition, verification, and deployment of advanced spacecraft software and mission systems. Working closely with flight software, ground software, autonomy, mission operations, guidance, navigation and control (GNC), communications, and spacecraft subsystem teams, you will help develop robust software architectures that enable reliable, autonomous, and mission-ready spacecraft operations. This position is ideal for an engineer who combines deep software expertise with strong systems engineering skills and enjoys leading multidisciplinary technical efforts across the full spacecraft lifecycle.

Where You'll Make an Impact

Architect and design of spacecraft software and system-level solutions supporting spacecraft programs
Develop and manage system requirements, interface definitions, technical baselines, verification plans, and traceability throughout the development lifecycle
Define and manage interfaces between Flight Software (FSW), Ground Software (GSW), mission operations systems, and spacecraft hardware
Collaborate with multidisciplinary engineering teams, including flight software, GNC, autonomy, communications, avionics, and mission operations, to develop, integrate, and validate spacecraft software capabilities
Conduct system architecture trade studies, technical assessments, and design analyses supporting program objectives
Lead technical reviews, risk assessments, architecture evaluations, and engineering decision processes
Support mission planning, concept of operations (ConOps) development, and mission execution planning
Mentor engineers while promoting systems engineering best practices, software quality, and technical excellence
Support customer interactions, executive briefings, design reviews, and technical presentations
Drive resolution of complex technical issues across software and spacecraft systems throughout the product lifecycle
Support continuous improvement initiatives that strengthen software architecture, and mission execution capabilities

What It Takes

Bachelor's, Master's, or Ph.D. in Aerospace Engineering, Systems Engineering, Computer Engineering, Electrical Engineering, Computer Science, or a related technical discipline
