Embedded Firmware & Edge Integration Engineer

Our client is an innovative technology company developing a next-generation IoT platform that combines embedded electronics, intelligent sensor systems, edge processing, environmental monitoring, adaptive control and cloud connectivity into a single connected solution.

The product is currently in the R&D phase and will be deployed and validated in real-world pilot environments, with a strong focus on reliability, safety, scalability and intelligent automation.

This is a unique opportunity to work on a greenfield product where embedded systems, IoT, cloud technologies and AI come together. Rather than maintaining an existing solution, you will contribute to building an innovative connected hardware platform from the ground up, working alongside multidisciplinary engineering teams and taking part in every stage of product development-from prototype to real-world deployment.

As an Embedded Firmware & Edge Integration Engineer, you will play a key role in developing the firmware that powers the platform. You will work closely with Systems Engineering, Backend/Cloud, AI/ML and Validation teams to integrate hardware, sensors and communication layers into a reliable, production-ready connected device.

This is a hands-on engineering role for someone who enjoys building, testing, debugging and integrating real-world embedded systems., The Embedded Firmware & Edge Integration Engineer will be responsible for developing embedded firmware and integrating hardware components into a reliable connected platform suitable for prototype validation and real-world deployment., * Developing firmware for microcontrollers and embedded modules
