Junior Firmware Engineer

We are looking for a passionate Embedded Firmware Engineer (1–2 years) to join our engineering team. The role involves developing, debugging, and maintaining embedded firmware for microcontroller-based products across industrial automation, IoT, fire & safety, and connected device applications. The ideal candidate should have a strong foundation in Embedded C programming, microcontroller peripherals, communication protocols, and embedded system debugging. The engineer will work closely with hardware, software, Linux, and testing teams to develop reliable, production-ready embedded products. We are looking for an enthusiastic engineer who is eager to learn, enjoys solving technical challenges, and is willing to grow into a complete embedded product development engineer.

Job Responsibilities
