Embedded Systems Engineer

Full Time Position - Auburn Hills, Michigan

Firefly is seeking a passionate Embedded Systems Engineer to develop the firmware and embedded control systems that power our cutting-edge drone platforms. In this role, you'll be responsible for designing, programming, and optimizing the low-level software that drives our flight controllers, smart batteries, lighting systems, and communication modules.

You'll work at the intersection of hardware and software — writing firmware in C / C++ for STM32 microcontrollers and integrating it directly with custom PCBs designed in-house. Your work will bring our drones to life, from bootloaders and device drivers to flight control algorithms and sensor interfaces.

We're looking for someone who enjoys solving complex problems, thrives in a hands-on, fast-moving environment, and isn't afraid to test their code on real hardware. Experience with PX4 or other flight control systems is a plus, but curiosity, initiative, and a willingness to learn are even more important.

Key Responsibilities

• Develop, test, and maintain embedded firmware in C / C++ for STM32 and similar ARM Cortex-M MCUs.
• Work with our PX4-based flight control stack (not required but preferred).
• Design and implement device drivers and control loops for sensors, ESCs, and battery systems.
• Collaborate with hardware and PCB engineers to integrate firmware and verify designs.
• Debug, optimize, and profile embedded code for performance and reliability.
• Participate in system bring-up, validation, and flight testing.
• Support development of test tools, firmware update mechanisms, and production scripts.
