Embedded Software Engineer
About The Position
Icarus is seeking an Embedded Software Engineer to build and ship flight-critical embedded software for long-endurance stratospheric aircraft. This role involves owning embedded subsystems end-to-end, including architecture, implementation, bring-up, debugging, testing, and flight validation. The engineer will write firmware for MCU-based avionics, sensors, actuators, power systems, and communication interfaces, as well as integrate sensors and peripherals. The position requires designing robust telemetry, logging, and health monitoring systems to support long-duration autonomous operations, and building test harnesses, HIL hooks, and automation to accelerate iteration loops. The role also includes supporting integration, production bring-up, and flight operations in the desert.
Requirements
- 1+ years working with real embedded systems — professional experience, internships or research (aerospace, robotics, automotive, defense, or similarly high-reliability domains)
- Strong C/C++ fundamentals and comfort working close to hardware
- Experience with RTOS or bare-metal firmware, interrupts, timing, and deterministic systems
- Experience with common embedded interfaces and protocols (SPI, I2C, UART, CAN, Ethernet)
- Strong debugging skills using scopes, logic analyzers, JTAG, and real-world fault reproduction
- Comfort moving fast, owning outcomes, and troubleshooting in the field
Responsibilities
- 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
Benefits
- 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
