Senior Software Engineer

Who We Are Picogrid is a leading venture-backed defense technology company founded to bridge the decades-long gap between modern technology and the critical demands of national security. Today, we're building the essential infrastructure to unify sensors, autonomy, and operators with our technology deployed in active operations around the world. Our mission is to deliver an operational advantage to secure the United States and its allies.

About The Role Legion is Picogrid's core platform: it connects sensors, cameras, drones, and third-party systems into a single operational picture that military users rely on in live missions. As a Senior Software Engineer, you'll own significant pieces of that platform end to end — from API design through deployment and operation in production.

You'll work on things like:

• Designing and building backend services in Go — REST and gRPC APIs and event-driven pipelines that serve real-time sensor and video feeds.
• Building integrations that connect Legion to hardware devices and common operating pictures (COP) like TAK, so data flows to operators wherever they are.
• Building command-and-control (C2) capabilities — tasking systems that let operators connect and task any device in the field, from cameras to drones to sensors, through a single interface.
• Designing the data models and ingestion pipelines that keep high volumes of telemetry, detections, and geospatial data queryable at mission scale.

Everything you build runs in production across cloud and disconnected edge environments, so the problems are system-level: data arriving from unreliable networks, integrations with hardware that doesn't follow the spec, and users who need the platform to work the first time, every time. You'll talk directly with the operators and partners who use what you build, and you'll frequently ship something one week that's used in the field the next.

This role fits an engineer who wants ownership over outcomes rather than tickets — someone who is comfortable making architectural decisions, holds a high bar for code quality and testing, and finds it motivating (not stressful) that their work has an immediate, tangible effect on national security.

Required Qualifications

• Strong background in APIs, distributed systems, data pipelines, or real-time processing.
• Deep experience with relational databases (e.g., PostgreSQL), object stores (e.g., S3, MinIO), and geospatial tools.
• Strong grasp of HTTP APIs (REST, gRPC, GraphQL) and authentication/authorization models.
• History of working directly with customers to build and deliver meaningful software.
• Demonstrated ability to operate with urgency, ownership, and high engineering standards.
