RF Engineer

Sine Engineering builds the technology behind reliable drone autonomy — communications, navigation, and control that keep multi-drones coordinated at once. Over 200 UAV manufacturers rely on our systems, and our technology powers most of the interceptor operations active today. Through a dual-use platform, we support civilian innovation while helping democratic nations strengthen their technological edge.

Any drone, any scale, anywhere — resilient communication, navigation, and coordination built for the age of autonomy. Our products have already proven themselves in real combat conditions in Ukraine.
