Flight Software Engineer

Responsibilities

• Design, implement, and maintain flight software services for sensing payload operations, onboard data handling, and resource management
• Build robust interfaces to hardware, including drivers, protocol integrations, and debugging tools
• Develop software for embedded Linux environments and constrained compute targets
• Build and improve data paths for collection, compression, storage, and downlink
• Partner with hardware and avionics teams to debug hardware/software interactions
• Use simulation, software-in-the-loop, and hardware-in-the-loop testing to validate behavior
• Improve build, test, and release workflows, including automated testing and artifact traceability

Requirements

• 2–6+ years of professional flight software, embedded software, or closely related systems experience
• Strong programming skills in Python and either C++ or Rust
• Experience with multi-threading, memory management, and performance optimization
• Hands-on experience with build systems like CMake or Make and embedded Linux
• Experience with low-level communication protocols and fault-tolerant system design
• Strong instincts for testing, reproducibility, and observability

Preferred Qualifications

• Experience designing CI/CD pipelines and automated test systems in GitLab
• Experience with hardware-in-the-loop testing or simulation infrastructure
• Experience architecting onboard data paths (filesystems, compression, buffering)
• Experience working with sensors, avionics, robotics, satellites, or aerospace systems

About the Company

Matter is building sensor infrastructure to read the Earth’s material fingerprint from orbit, turning previously inaccessible data into critical intelligence for industries like agriculture, mining, and environmental monitoring. Founded by engineers and scientists with deep NASA/JPL roots, Matter combines meticulous science with the speed of an early-stage startup.
