Software Engineer - Core Platform

Who We Are

Picogrid builds hardware and software infrastructure to connect and control the systems that power critical industries. Our platform unifies sensors, platforms, and operators to power mission planning, autonomous system control, and real-time decision‑making. We partner directly with operators, technology companies, and federal agencies to deliver rapidly deployable, mission‑critical capabilities where they’re needed most, often on short timelines and in challenging conditions.

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.

Picogrid is seeking a Staff Software Engineer to drive our core platform, Legion. Legion is a data integration platform used by operators around the world to integrate, command, and coordinate unmanned systems at massive scale. You will solve complex problems including data federation in communications‑degraded environments, multi‑sensor data fusion, and coordination across swarms of unmanned systems. In this role you will design, build, and deploy high‑performance, scalable software systems that power critical defense missions, focusing on the backend platform and integration tools that support the next generation of connected defense infrastructure.

As a Staff Software Engineer, you’ll play a key role in delivering real‑time, reliable, and secure software solutions that function seamlessly across hybrid environments. You’ll work across microservices, APIs, data pipelines, and integration tooling to help unify field systems and bring autonomy to the edge. This position involves more than just code—it requires deep systems thinking, strong collaboration, and the ability to work directly with end users to solve real operational challenges.
