You will design, build, and execute structured software test procedures that validate payload application software across integration milestones, system-level campaigns, and environmental test events. You will assist the payload software team in the test and validations of new feature additions to the system. You will translate requirements, ICDs, and operational concepts into repeatable, high-signal procedures with objective pass/fail criteria, then execute those procedures on real hardware and integrated test environments to produce flight-ready verification evidence.

What You'll Do:

• Develop and execute test plans for software/hardware interface components of the satellite payload system.
• Design and implement automated test scripts and frameworks for testing communication protocols, sensor interactions, and hardware control.
• Perform various types of testing, including unit, integration, functional, and performance testing, with a focus on hardware interaction.
• Identify, document, and track software defects and hardware-related issues.
• Contribute to the development and improvement of testing processes and tools.

Required Qualifications:

• Programming Languages: C/C++, Bash, Python
• Communication Protocols: Knowledge of common protocols like SPI, I2C, UART

Preferred Qualifications:

• Hardware Interaction: Experience with hardware debugging tools, oscilloscopes, logic analyzers (if possible)
• Experience with embedded systems testing.
• Familiarity with aerospace testing standards.
• Experience with continuous integration/continuous delivery (CI/CD) pipelines.
