The Role

\n

A technical, hands-on role where you will:

\n

\n
• Architect and implement safety-critical C/C++ flight software for spacecraft operations.
\n
• Develop real-time embedded Linux software for avionics, propulsion, thermal, and payload subsystems.
\n
• Build autonomous decision-making and Fault Detection, Isolation, and Recovery (FDIR) software.
\n
• Architect and execute comprehensive SIL (Software-in-the-Loop) and HITL (Hardware-in-the-Loop) test harnesses.
\n
• Design spacecraft-to-ground communication protocols and telemetry pipelines.
\n
• Support hardware-software integration, launch preparation, and on-orbit commissioning.
\n

The Essential Requirements

\n

\n
• U.S. Person status required due to U.S. export control regulations (ITAR/EAR).
\n
• 7+ years experience developing flight software for spacecraft or safety-critical platforms.
\n
• Expert proficiency in C/C++ for real-time embedded systems (Linux or RTOS like VxWorks/FreeRTOS).
\n
• Proven track record building automated SIL and HITL test environments.
\n
• Willingness to work on-site in Denver, CO, with occasional travel to launch/recovery zones.
\n

What Will Make You Stand Out

\n

\n
• Experience with atmospheric reentry, heat shields, or hypersonic vehicle controls.
\n
• Practical knowledge of Rust for embedded platforms.
\n
• Familiarity with aerospace safety standards (DO-178C, NASA-STD-8739.8) or spacecraft protocols (CAN, RS-422).
