Software Engineer

Hardware-in-the-Loop (HIL) Software Engineer

Red Canyon Engineering & Software is seeking a Hardware-in-the-Loop (HIL) Software Engineer to develop and integrate spacecraft simulation and test environments.

This role connects simulation models and hardware emulators to physical avionics, enabling flight software, guidance, navigation and control (GNC), and fault management testing.

Responsibilities

• Develop and integrate a mini-HIL/HWIL test environment connecting spacecraft simulations and emulators to avionics hardware.

• Connect simulation software to United Electronic Industries (UEI) hardware and verify interface functionality.

• Develop and maintain C/C++ simulation models and Python scripts for integration, testing, and data analysis.

• Configure and troubleshoot RS-422, MIL-STD-1553, SpaceWire, GPIO, and analog-to-digital interfaces.

• Validate simulation outputs and hardware responses against expected system behavior.

• Investigate timing, communication, and hardware/software integration issues.

• Configure and maintain Docker-based simulation and test environments.

• Collaborate with flight software, GNC, and systems engineers to support integration and fault management testing.

• Document testbed configurations, integration procedures, and validation results.

Required Qualifications

• Experience developing software for HIL/HWIL, simulation, emulation, or comparable embedded systems test environments.

• Proficiency in C/C++ and Python.

• Experience integrating simulation models or emulators with physical hardware.

• Working knowledge of embedded systems and hardware/software interfaces.

• Experience with one or more of the following: RS-422, MIL-STD-1553, SpaceWire, GPIO, or analog/digital I/O.

• Ability to analyze simulation results, troubleshoot discrepancies, and validate system behavior.

• Strong technical communication and documentation skills.

Preferred Qualifications

• Experience with UEI hardware and software interfaces.

• Experience with the NASA Trick simulation framework.

• Experience with Docker and containerized development environments.

• Spacecraft or launch vehicle simulation and test experience.

• Familiarity with software-in-the-loop (SIL/SWIL) and flat-sat environments.

• Familiarity with GNC testing and fault detection, isolation, and recovery (FDIR).
