Senior Mechanical Engineer

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 Design and fly lightweight, high-reliability structures for stratospheric aircraft Own mechanical subsystems from concept to flight Perform first-principles sizing, trade studies, and rapid iteration Build, test, break, and refine flight hardware Support integration, production, and flight operations Work closely with avionics, GNC, power, RF, and software teams What we’re looking for 2+ years designing, analyzing, or building real mechanical hardware Strong fundamentals in structures, materials, and first-principles engineering Experience with lightweight structures, composites, sheet metal, or bonded assemblies Comfortable moving fast, owning outcomes, and working hands-on in the factory and field Why Icarus Meaningful equity Top market salary and bonuses Health, dental, and vision insurance Factory in El Segundo Real ownership, real hardware, real flight Small team, massive responsibility High signal (engineering) to noise (management) culture Dream desk setup Daily lunch Unlimited celsius 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.
