Job summary

Red Canyon Engineering & Software is seeking a Simulation Software Engineer to develop and maintain spacecraft simulation environments. You'll model processors and interfaces using Renode/QEMU, integrate COSMOS for testing, and support software-in-the-loop and hardware-in-the-loop activities.

You will collaborate with flight software and systems teams to validate virtual testbeds, ensure test accuracy, and document architectures. A related degree and hands-on embedded experience are required.

Qualifications

• Experience developing or supporting embedded-system simulation, emulation, or software test environments.
• Hands-on experience with COSMOS.
• Experience using Renode and/or QEMU for processor, hardware, or embedded-system emulation.
• Software development experience with languages such as C, C++, or Python.
• Understanding of embedded software, processor architectures, hardware/software interfaces, and real-time system behavior.
• Experience developing automated tests or test-support software.
• Strong troubleshooting, communication, and cross-functional collaboration skills.

Responsibilities

• Develop, configure, and maintain simulation and emulation environments for spacecraft and embedded flight systems.
• Use Renode and/or QEMU to model processors, peripherals, interfaces, and embedded-system behavior.
• Configure and integrate COSMOS for command, telemetry, automated testing, and system validation.
• Support the execution and testing of flight software in virtual and hardware-independent environments.
• Develop software models representing spacecraft components, sensors, actuators, communications interfaces, and other system behaviors.
• Create automated test scripts, test utilities, and simulation tools for software verification and validation.
• Troubleshoot issues involving flight software, simulated hardware, telemetry, commands, and system interfaces.
• Collaborate with flight software, systems engineering, test, mission operations, and hardware teams.
• Support software-in-the-loop, processor-in-the-loop, and potentially hardware-in-the-loop testing.
• Document simulation architecture, interfaces, configurations, test procedures, and results.
• Participate in technical reviews and help improve simulation and testing capabilities.
