Senior Software Test Engineer

Who we are

Picogrid envisions a future where every system, from the smallest sensors to next-generation fighter jets, can collaborate autonomously to create a safer and more prosperous world for all.

Today, we are at the forefront of American defense technology, developing a unified platform that integrates fragmented technologies—such as sensors, cameras, radar, and drones—into sophisticated mission systems.

Our technology is deployed globally, supporting customers including the U.S. Army, U.S. Air Force, CAL FIRE, PG&E, U.S. Fish and Wildlife, and many others.
