Overview of Role

n

This role is responsible for supporting the development, verification, and continuous improvement of Fiber Optic Gyroscope (FOG) technologies and their integration into inertial navigation systems.

n

The Senior Fiber Optic Gyroscope Engineer will apply strong analytical and practical engineering skills across optical components, fiber coils, gyro performance, environmental testing, and system-level troubleshooting. The role requires close collaboration with photonics, electronics, FPGA, mechanical, algorithm, manufacturing, and calibration teams to translate test results into meaningful engineering actions.
