You can't get experience working on inertial guidance systems just anywhere. Because they invented an optical gyro, they have an inertial guidance product you can hold in your hand. Their product is sophisticated and interesting to work on. Probably nothing like you've done before. They work in C and Python.
Cons
Because they are relatively new, they have a long way to go implementing software engineering best practices and the company/everyone will benefit when they mature as a team.
