The Mission
Space is the bleeding edge for humanity's next industrial revolution. At Lux Aeterna, we're building the infrastructure that makes orbit as accessible and reliable as air travel. Our reusable satellite platform requires a ground software system capable of commanding, monitoring, and operating spacecraft with precision and reliability—the digital mission control center that brings satellites home safely.
The Opportunity
We're seeking a Ground Software Engineer to architect and build the mission control systems that will command our reusable satellite platform. You'll design real-time ground station software, build mission automation tools, and create the interfaces that enable operators to conduct complex space missions reliably. This is an opportunity to:
Design and implement mission control systems for autonomous spacecraft operations
Build telemetry processing and visualization systems
Create ground station automation that minimizes operator workload
Develop fault-tolerant high reliability systems for mission-critical operations
Join a rapidly growing team solving infrastructure challenges at scale
Why Lux Aeterna?
Pioneering Technology: We're developing the first reusable satellite platform with controlled return capability, fundamentally transforming space from a one-way journey to a two-way trade route
Real Impact: Your work will enable new industries in space manufacturing, research, and logistics while pioneering sustainable space infrastructure
Speed & Autonomy: We maintain parallel hardware development streams and empower engineers to innovate rapidly while upholding rigorous aerospace standards
World-Class Team: Work alongside experts from leading aerospace companies and research institutions, building technology that will reshape humanity's access to space
The Role
You'll own the ground software architecture for spacecraft mission control and operations.
Design and build mission control systems (command, telemetry, automation)
Develop systems for command routing, telemetry acquisition, data processing, and visualization
Create operational automation tools that streamline daily mission operations tasks
Architect ground station network infrastructure
Build integrated test and simulation systems with flight software
Implement time-series databases and data processing pipelines
Design intuitive operator interfaces and dashboards
Support satellite operations, commissioning, and on-orbit troubleshooting
Collaborate with flight software, GNC, RF, and mission operations teams
Required Qualifications
B.S. in Computer Science, Computer Engineering, or related technical field
5+ years developing software for spacecraft operations, mission control, or ground systems
Experience with mission / satellite operations (SatOps) platforms and workflows
Strong proficiency in Python, C++, or Go for backend systems development
Solid understanding of networking protocols (TCP/IP, UDP)
Proficiency with relational and/or time-series databases (PostgreSQL, InfluxDB, Prometheus, etc.)
Experience integrating with ground station service providers (KSAT, Atlas, or similar)
Proficiency with version control (Git), CI/CD pipelines, and automated testing
Familiarity with cloud platforms (AWS or equivalent)
Desired Experience
M.S. in Computer Science, Computer Engineering, or related field
Experience processing and visualizing spacecraft telemetry streams
Deep experience with spacecraft communication protocols (CCSDS)
Background with monitoring and visualization tools (Grafana, Prometheus)
Experience with containerization (Docker, Kubernetes)
Familiarity with RF communications and ground station hardware
Contributions to open-source aerospace or robotics projects
Location & Work
We are based in Denver, CO and believe in the power of in-person collaboration. We are onsite 5 days/week by default, but flexible when life requires it.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.
