Swarm Aero is redefining air power, building the largest swarming UAV and the most versatile swarming aircraft network in the world. The company is moving quickly to launch the first aircraft designed specifically for swarming, as well as the Command & Control software to mobilize swarms of thousands of heterogeneous autonomous assets and empower human operators to achieve superhuman results.

The team has created and exited multiple startups, negotiated defense deals worth billions of dollars, and designed and built 30+ novel aircraft, with aerospace experience from Scaled Composites, Airbus, Archer Aviation, Blue Origin, and Boom Supersonic.

Most full stack roles ask you to move pixels around a dashboard. This one asks you to build the interface that controls the largest drone swarm on the planet.

You'll help architect the frontend for Legion's Command & Control platform: the software that lets 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, dense telemetry visualization, and interface design for a problem space that barely has prior art.

What You'll Do

Help architect the frontend 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 ship new UI concepts for representing vehicle telemetry, sensor data, scheduling, crew resources, data link management, and more, much of it with no existing playbook to follow

Own full stack 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 full stack applications with real frontend and backend depth

Strong UI/UX instincts and the tools to back them up

Built production web interfaces with React or a comparable modern framework

What Sets You Apart

Experience with both immediate mode (games, simulation) and retained mode UI paradigms

A track record with performance-sensitive application development

Familiarity with video streaming protocols

WebGL/OpenGL experience

Working fluency in C++

Experience with geospatial 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.

What We Offer

Meaningful equity in a high-growth defense technology company

Competitive base salary commensurate with experience

Medical, dental, vision, and 401k

PTO and paid sick leave

Monthly wellness stipend

Daily catered lunch (office)

Paid parental leave

Direct impact on a critical national security mission

A world-class team of engineers and operators solving genuinely hard problems
