Senior Embedded Software Engineer - Real-Time Avionics

Elroyair; Byron (CA); On-site; USD 140,000 - 190,000; Full time

Job summary

Elroy Air is building autonomous VTOL cargo aircraft systems to transform how goods move. The embedded software team writes the code that flies the plane in real conditions, spanning bare-metal firmware to hardware bring-up.

As a Senior Embedded Software Engineer, you will own software on safety-critical avionics hardware, collaborate across disciplines, and help grow a small, senior, cross-functional team that values curiosity and practical engineering.

Qualifications

• 5+ years of professional embedded software development with production firmware shipped on real hardware.
• Deep fluency in C and/or C++; Python for scripting and tooling.
• Hands-on experience with at least one RTOS and bare-metal development.
• Comfort reading schematics and debugging hardware/software integration at the signal level.
• Experience with SPI, I2C, UART, CAN, Ethernet.
• Strong opinions about code quality and testability; differentiating lab vs field software.

Responsibilities

• Embedded firmware for microcontrollers and SoCs in bare-metal or RTOS environments (FreeRTOS, Zephyr, or similar).
• Driver development, peripheral integration, and board bring-up for custom hardware platforms.
• Real-time control loops and sensor fusion pipelines requiring determinism.
• Hardware debugging using oscilloscopes, logic analyzers, JTAG; read schematics as needed.
• C++ and Python tooling for testing, scripting, and automation around embedded targets.
• Develop models and emulators for aircraft components to align hardware behavior with cloud simulations.
