Principal Integration & Test Engineer

About the role

We are seeking a Principal Integration & Test (I&T) Engineer to support the development, integration, debugging, and verification of space payload systems. This role requires a hands-on engineer who can work across software, firmware, and electronics to troubleshoot complex system issues and ensure payload readiness for lab, environmental, and flight test activities.

Responsibilities

• Debug and troubleshoot issues spanning application software, embedded software, FPGA/firmware interfaces, electronics, sensors, and communication links.
• Support bring-up of payload electronics, processors, FPGAs, data interfaces, and support equipment.
• Investigate failures during integration and test using lab equipment, logs, telemetry, and software/firmware diagnostics.
• Use lab equipment such as oscilloscopes, logic analyzers, power supplies, DMMs, protocol analyzers, and signal generators to diagnose hardware and interface issues.
• Support checkout and debugging of interfaces such as SPI, I2C, UART, RS-422/485, Ethernet, SpaceWire, CAN, and other mission-specific buses.
• Work closely with software, firmware, electrical, systems, and mechanical engineers to resolve integration issues and improve design robustness.
• Document test results, anomalies, troubleshooting steps, and corrective actions to support formal verification and flight readiness reviews.
• Absorb system-level and environmental testing, including functional test, thermal vacuum, vibration, EMI/EMC, and mission simulations.
• Contribute to development of testbeds, lab infrastructure, automated test tools, and debug processes.
• Support configuration management and ensure testing is performed against the correct hardware, firmware, and software baselines.

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering, or related field (OR equivalent years of experience / combined education).
• 9 or more years of related experience.
• Experience integrating and testing embedded systems, avionics, or aerospace hardware.
• Ability to debug across software, firmware, and electronics.
• Experience reading and interpreting schematics, ICDs, test procedures, requirements, and design documentation.
• Experience with embedded debugging tools, logs, telemetry, and lab instrumentation.
• Familiarity with C/C++, Python, or similar scripting languages for test automation and troubleshooting.
