Associate software engineer Jobs in Westminster, CO

The Mission Space is the bleeding edge for humanity's next industrial revolution.

While reusable rockets have opened the door, true economic transformation requires infrastructure that makes orbit as accessible and reliable as air travel.

At Lux Aeterna, we're building that future by developing the first reusable satellite platform with controlled return capability - transforming space from a one-way street into a two-way highway for innovation and commerce.

The Opportunity We're seeking an experienced Flight Software Engineer to develop and validate the software that will command our revolutionary reusable satellite platform.

You'll build safety-critical systems that operate autonomously in the harshest environment known to humanity, and own the testing strategy to ensure they work flawlessly in orbit and during atmospheric reentry.

This is a unique opportunity to :

• Develop flight software architecture for autonomous spacecraft operations Build real-time embedded systems that control everything from propulsion to payload operations Design and implement comprehensive testing strategies for safety-critical code Create fault-tolerant software that handles the unexpected in orbit and during reentry Join a rapidly growing team with the resources to tackle ambitious technical challenges Why Lux Aeterna?

Pioneering Technology :

Architect and implement flight software for spacecraft operations Develop Linux-based software for avionics, propulsion, thermal, and payload subsystems Build autonomous decision-making algorithms for mission-critical operations Create robust fault detection, isolation, and recovery (FDIR) software Design and implement spacecraft-to-ground communication protocols and telemetry systems Architect distributed flight software systems across multiple spacecraft subsystems Architect and build comprehensive software-in-the-loop (SIL) and hardware-in-the-loop (HITL) test frameworks Develop test automation pipelines and validate flight software across all subsystems Work with security-hardened systems for spacecraft command and data integrity Support integration, testing, and on-orbit commissioning of flight software Collaborate with GNC, avionics, and mission operations teams to ensure seamless system integration Required Qualifications B.S. in Computer Science, Computer Engineering, Electrical Engineering, or related technical field 5+ years of experience developing flight software for spacecraft or safety-critical systems Expert proficiency in C / C++ for flight software development Strong experience developing Linux-based flight software for satellites or embedded systems Experience with real-time operating systems (RTOS) such as VxWorks, FreeRTOS, or similar Strong understanding of embedded systems constraints :
