About The Position

Icarus was founded on the belief that the Stratosphere is the Forgotten Frontier and that reclaiming it will define the next era of aerospace and what is possible from the sky. We build solar-powered aircraft that fly at 60,000 ft for weeks at a time, delivering persistent, affordable, and scalable presence from this layer of the atmosphere. Mission Re-establish and maintain dominance in the Stratosphere. What you’ll do Build and own end-to-end software systems that power flight operations, autonomy, and user interaction Develop mission-critical backend services for telemetry, command and control, data ingestion, and analytics Build clean, fast frontends for ground control, monitoring, and operator workflows Design APIs and data pipelines that connect aircraft, ground stations, and users Work closely with embedded, avionics, GNC, RF, and operations teams to ship tightly integrated systems Support flight test, field ops, and rapid iteration using real flight data Take systems from concept to production with speed and ownership This is not a normal engineering job We are pioneers, not corporate managers. Icarus deliberately optimizes for a high signal (engineers) to noise (management) ratio, where engineering, flight, and execution matter more than process, politics, or management overhead You will work side by side with the CEO and a small team of world-class builders. You will own your subsystem end to end. Design it. Build it. Break it. Fix it. Validate it in the desert. Fly it. Then do it again, faster We expect full extreme ownership. This is a high-trust, no-BS team, and everyone pulls their weight We are hiring across the stack: mechanical, aerodynamics, RF, GNC, electrical, avionics, power electronics, energy storage, software, and systems We want builders. No hand-holding. No fluff. No fake projects. No slide decks. No sitting in meetings all day. Just raw engineering, real hardware, and real flight You must thrive under pressure, learn fast, troubleshoot in the field, and push hardware to its limits. We move fast. We go to Mojave at 4 am in the morning. We expect results and an obsession with quality and speed You will be a core executor of flight hardware, taking systems from concept to reality and driving rapid iteration loops. You will work across avionics, power electronics, energy storage, integration, and production bring-up. If you want real ownership, real hardware, and real flight milestones, this is it No tourists. No bystanders. Only builders.
