Spacecraft Ground Software Engineer II

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 a highly skilled Spacecraft Ground Software Engineer II to lead the development, integration, and operational support of software systems that enable spacecraft testing, mission operations, and real-time ground communications.

This role is ideal for an experienced software engineer who thrives at the intersection of distributed systems, mission operations, infrastructure, and real-time data processing. You will play a key role in building the software platforms and operational tooling that support spacecraft integration, command and telemetry workflows, and mission readiness throughout the vehicle lifecycle.

You will work closely with flight software, AI&T, mission operations, avionics, and systems engineering teams to develop scalable and reliable ground software solutions that support both integration and on-orbit operations.

Where You’ll Make an Impact 

• You get to build the architecture upon which the ground software will be run
• Your work directly impacts safety, reliability, and the mission's success
• Ground software touches each part of the mission from testing to on-orbit operations
• You will own major pieces of the architecture end-to-end
• You have the opportunity to influence coding standards, architecture, and how we operate as a team
• You get mission-critical responsibility that will support mission operations long after the first launch
