Staff Software Engineer, Real-Time Systems

About the role

This role asks you to build the systems that keep the largest drone swarm on the planet coordinated in real time. You'll help architect the backend for Legion's Command & Control platform: the systems that let a single operator plan, direct, and execute missions across a networked swarm of heterogeneous aircraft, in real time, over intermittent comms, at a scale nobody else in the industry is attempting. This isn't CRUD. It's real-time distributed systems, high-throughput telemetry pipelines, and infrastructure for a problem space that barely has prior art.

What You'll Do

• Help architect the backend for a C2 system directing swarms of heterogeneous aircraft
• Build distributed, collaborative real-time infrastructure for controlling large numbers of aircraft simultaneously, even when comms drop
• Design and build the services that ingest, process, and distribute dense vehicle telemetry, sensor data, scheduling, crew resources, and data link management, much of it with no existing playbook to follow
• Own backend features end to end, from design through deployment
• Ship early, ship often, backed by strong CI/CD, QA, and DevSecOps

What You've Done

• Degree in Computer Science or equivalent experience
• 6+ years building complex backend systems with real distributed systems depth
• Strong instincts for reliability, performance, and scalability, and the tools to back them up
• Built and operated production backend services and APIs at scale

What Sets You Apart

• Experience with real-time and event-driven distributed systems
• A track record with performance-sensitive, high-throughput application development
• Familiarity with messaging and streaming protocols
• Experience operating systems under degraded or intermittent connectivity
• Experience with geospatial data or applications

Why This Role

You'll be one of the earliest engineers shaping how humans command autonomous systems at scale, work that's currently being defined in real time, by a small team, with your fingerprints on the architecture. If you want to build the future of human-swarm interaction rather than maintain someone else's, this is that seat.
