About Sine Engineering
Sine Engineering builds the technology behind reliable drone autonomy, including communication, navigation, and control systems that enable coordinated multi-drone operations at scale. More than 200 UAV manufacturers rely on our technologies, and our solutions power many of the interceptor operations active today.
Through our dual-use platform, we support civilian innovation while helping democratic nations strengthen their technological advantage.
Any drone. Any scale. Anywhere.
We build resilient communication, navigation, and coordination systems for the age of autonomy. Our products have already proven their effectiveness in real combat conditions in Ukraine.
We are looking for a talented RF Engineer to contribute to the development, testing, and evaluation of RF devices and systems. This role involves working with high-frequency measurement equipment, preparing test benches, analyzing measurement results, and creating technical documentation.
