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.

Legion's Command & Control platform 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.

What you'd do

Competitive programming background (ICPC, IOI, Codeforces, USACO, Putnam)
Game development, game jams, engine work, or simulation
