Senior Embedded Software Engineer at Icarus

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. Re-establish and maintain dominance in the Stratosphere. Build and ship flight-critical embedded software for long-endurance stratospheric aircraft Own embedded subsystems end to end: architecture, implementation, bring-up, debugging, test, and flight validation Write firmware for MCU-based avionics, sensors, actuators, power systems, and comms interfaces Integrate sensors and peripherals (IMU, GNSS, air data, magnetometer, servos, radios) and build reliable drivers and middleware Design robust telemetry, logging, and health monitoring to support long-duration autonomous operations Build test harnesses, HIL hooks, and automation that makes iteration loops faster Support integration, production bring-up, and flight ops in the desert 2+ years shipping real embedded systems (aerospace, robotics, automotive, defense, or similarly high-reliability d
