About The Position

We are seeking a creative and experienced Firmware Engineer to join our dynamic team. We need someone passionate about designing, developing, and maintaining firmware for microcontroller-based products. This role involves working closely with hardware engineers to implement reliable, efficient firmware that interfaces directly with sensors, communication peripherals, and real-time control systems. The ideal candidate is comfortable working close to the hardware, debugging at the register level, and bringing products from early prototypes through production. Additionally, this role involves ensuring the integrity of our final products by addressing complex cross-functional engineering problems.

Requirements
