Rust Backend Engineer

Flight Science is building next-generation operations software for the airline industry. Our mission is to give flight operations teams real-time, intelligent tools that improve efficiency, communication, and decision‑making. Our first product uses real-time flight tracking, weather, and airspace data to power in‑flight optimization, delivering recommendations to pilots that save fuel, avoid turbulence, and reduce delays.

2026 is a year of massive scaling for Flight Science. Following a successful year where we closed both our pre‑seed and seed rounds, we are well‑capitalized and ready to expand our product suite for major airline partners.

We are looking for aSenior Rust Backend Engineerto take a significant, highly visible role designing and developing our backend systems and infrastructure. You will build and maintain performance‑critical services that power low‑latency APIs and real‑time data pipelines for dispatchers, pilots, and airline operations centers. Additionally, you willhelp shape our cloud infrastructure, deployments, and release management, ensuring that our mission‑critical systems are deployed safely and scale seamlessly as our customer list grows.
