Picogrid builds hardware and software infrastructure to connect and control the systems that power modern defense operations. Our platform unifies sensors, drones, AI models, and operators into a single operational interfacepowering mission planning, autonomous system control, and real-time decision-making for some of the most capable units in the world.

We partner directly with military operators, defense technology companies, and federal agencies to deliver rapidly deployable, mission-critical capabilities where they're needed mostoften on short timelines, in challenging conditions, and alongside real-world operators. Our technology is trusted in active operations, not just test environments, and we move quickly to close real-world capability gaps for those on the front lines.

Joining Picogrid means working on high-impact problems at the intersection of autonomy, national security, and cutting-edge technology. You'll be part of a small, elite team that builds and ships systems used by the most capable defense organizations in the world. We operate with urgency, ownership, and a deep respect for the mission.
