Flight Software I&T Engineer

Flight Software Integration & Test Engineer — SIL/HIL

Red Canyon Engineering & Software is seeking a Flight Software Integration & Test Engineer to develop and execute automated tests for spacecraft flight software across software-in-the-loop (SIL/SWIL) and hardware-in-the-loop (HIL/HWIL) environments.

This role focuses on translating requirements and mission scenarios into comprehensive tests that verify vehicle behavior, identify defects, and demonstrate system readiness.

Responsibilities

• Develop and execute flight software tests across SIL, mini-HIL, and full HIL environments.

• Analyze system and software requirements to define test cases, expected results, and verification criteria.

• Develop Python scripts to automate test execution, data collection, and result analysis.

• Perform black-box testing of spacecraft functions and mission scenarios.

• Expand test coverage for vehicle initialization, commanding, subsystem control, and mission execution.

• Develop tests for nominal operations, off-nominal conditions, and fault management responses.

• Analyze telemetry, logs, and simulation outputs to assess system behavior.

• Investigate test failures and work with software, GNC, and systems engineers to resolve issues.

• Maintain test procedures, requirements traceability, and verification evidence.

• Support regression testing as flight software and simulation environments evolve.

Required Qualifications

• Experience testing flight software, embedded software, or comparable mission-critical systems.

• Proficiency in Python for test automation and data analysis.

• Experience with black-box testing and requirements-based verification.

• Experience testing in SIL/SWIL, HIL/HWIL, or comparable simulation environments.

• Ability to interpret telemetry and logs, investigate failures, and document findings.

• Strong analytical, communication, and collaboration skills.

Preferred Qualifications

• Spacecraft or launch vehicle flight software testing experience.

• Experience with flat-sat test environments.

• Familiarity with GNC integration and testing.

• Experience testing fault management, system autonomy, or fault detection, isolation, and recovery (FDIR) functionality.

• Familiarity with C/C++, Docker, and the NASA Trick simulation framework.

Benefits

Eligible employees may receive medical, dental, and vision insurance, retirement benefits, paid time off, and additional benefits based on employment classification.
