We're looking for a GNC Hardware Test Engineer to help build, integrate, and validate sensor and test hardware for spacecraft GNC systems. This is a hands-on lab role ideal for someone who enjoys working across sensors, embedded hardware, test software, and rapid prototyping.

What You'll Do

• Build and maintain test jigs to evaluate GNC sensor performance.

• Integrate and test sensors such as IMUs, magnetometers, GNSS receivers, sun sensors, Earth horizon sensors, and star trackers.

• Develop and debug sensor communication over interfaces such as SPI, I2C, UART, and CAN.

• Support hardware-in-the-loop test setups for GNC software, sensors, actuators, and flight-like interfaces.

• Use platforms such as Raspberry Pi, Arduino, Pixhawk, or similar embedded systems for prototyping and test automation.

• Design simple fixtures, mounts, and test equipment using 3D printing and rapid prototyping methods.

• Write scripts and test tools in Python, MATLAB, and C++.

• Work with GNC, avionics, software, and systems engineers to troubleshoot issues and validate hardware performance.

Required Qualifications

• Hands-on experience with hardware testing, sensor integration, embedded systems, robotics, aerospace projects, or similar lab-based engineering work.

• Familiarity with navigation or attitude sensors such as IMUs, magnetometers, GNSS, sun sensors, Earth horizon sensors, or star trackers.

• Experience with communication interfaces such as SPI, I2C, UART, CAN, or similar protocols.

• Experience with Python, MATLAB, and/or C++ for test scripting, data analysis, or embedded development.

• Ability to troubleshoot hardware/software interface issues using lab tools and structured debugging methods.

• Strong hands-on engineering mindset and willingness to learn in a fast-paced lab environment.

Desired Qualifications

• BS or MS in Aerospace Engineering, Electrical Engineering, Computer Engineering, Robotics, Mechanical Engineering, or a related field.

• Internship, academic, research, or professional experience with spacecraft, UAVs, robotics, avionics, or embedded systems.

• Exposure to hardware-in-the-loop testing, real-time simulation, or automated test systems.

• Experience using Raspberry Pi, Arduino, Pixhawk, or similar platforms.

• Experience with 3D printing, CAD, and rapid fixture design.

• Familiarity with Linux, Git, oscilloscopes, logic analyzers, and general lab equipment.
