Icarus Tech Stack

Long-endurance stratospheric aircraft for persistent aerial connectivity

Defense and Space Manufacturing El Segundo, California 2–10 employees Founded 2023 Privately Held

Icarus builds high-altitude autonomous aircraft designed for sustained operation in the stratosphere. The tech stack—C/C++, RTOS, GNSS, Python, Go, Rust, React—spans embedded systems, flight control, and ground operations, typical of aerospace hardware-software integration. Hiring is heavily engineering-focused (12 of 13 roles) at senior levels, and projects cluster around flight-proven GNC systems, lightweight structures, and production ramp—signaling a company transitioning from prototype validation toward manufacturing scale. Pain points around build-process speed and hardware quality reflect the hard constraint of moving from garage/desert testing to factory production.

About Icarus

Icarus designs and manufactures long-endurance stratospheric aircraft for persistent aerial sensing and connectivity. Founded in 2023 and based in El Segundo, California, the company has progressed from prototype development ("proven in the desert") to establishing production capabilities. Core work spans guidance-and-control systems, composite structures, avionics, and power systems—all designed for the extreme environment of sustained stratospheric flight. The team is actively hiring across embedded systems, flight software, and manufacturing disciplines to accelerate production ramp and improve build consistency.
