Senior Firmware Engineer, Ground Software

Responsibilities

• Design, build, and maintain firmware for ground control hardware on microcontroller and embedded Linux targets.
• Own operator input handling, aircraft communication links, telemetry, video reception, and control-path latency and reliability.
• Define the ground side of the aircraft-to-ground interface with the flight software team, including degraded-link behavior.
• Bring up and debug new ground hardware with electrical engineering using oscilloscopes and logic analyzers.
• Write unit and integration tests and partner with the test organization on hardware-in-the-loop and field testing.

Requirements

• Strong embedded C, C++, or Rust experience in resource-constrained environments, including firmware shipped on real hardware in the field.
• Real-time firmware experience with interrupts, DMA, timing budgets, and load-related debugging.
• Hands-on board bring-up and hardware debugging experience.
• Working knowledge of UART, SPI, I2C, USB, and Ethernet communication interfaces.
• Experience taking firmware from first boot to production with light direction.
• Appropriate test discipline for field-reliable firmware.
• Preferred experience with embedded Linux, Yocto or Buildroot, Linux networking, IP-based radio or datalink integration, embedded video pipelines, and RC or ground controller firmware such as ExpressLRS or EdgeTX/OpenTX.

Benefits
