Ever wondered why airline operations feel so archaic? Join a well-capitalized, venture-backed startup based in London and NY that is rewriting the rules of global flight. We are building a mission-critical platform to replace legacy infrastructure for the world's largest airports and airlines. Working in a small, elite team led by an Apache Arrow contributor, you'll use Rust and Flutter to solve deep technical challenges that impact how billions of people travel. If you want high ownership, meaningful EMI equity, and the chance to build systems where performance and reliability are non-negotiable, this is your next move.
