Full-cycle embedded systems and IoT product development from concept to manufacturing

Appliances, Electrical, and Electronics Manufacturing Zagreb, Zagreb 51–200 employees Founded 2011 Privately Held

Byte Lab designs and manufactures embedded hardware and firmware products across IoT and edge AI, with a tech stack anchored in ARM, ESP32, and real-time OS kernels (FreeRTOS, Zephyr, ThreadX). The hiring pattern — all 18 active roles in engineering, weighted toward mid and senior levels — combined with internal projects focused on testing infrastructure and PCB design, suggests the company is scaling manufacturing capacity and QA rigor rather than headcount sprawl across non-technical functions.
