Senior Embedded Systems Developer

Work at DSR is your chance to dive into the interesting world of wireless devices of various types using modern IoT protocols (BLE, Zigbee, Matter, etc.). The range of tasks, which our engineers are working on includes integration of IoT devices into existing ecosystems from Amazon, Control4, Legrand, etc. and development of our own products. Our teams work on various projects, which include firmware development for MCU and wireless SoC (under RTOS control or bare metal) and development for embedded systems based on Linux.

We are developing firmware for the wide range of devices, including:

• IoT gateways/smart home centers that support one or more IoT protocols simultaneously.
• Sensors for smart home systems, which allow used to control various environmental conditions.
• Wearables for sport and everyday life.
• Smart devices for pets, allowing users to control health and location of their pets and control animals access to their house.

There is also a Zigbee stack among our products and we keep improving it to gather more and more recognition from major Zigbee device vendors and it has already become an official stack for Nordic Semiconductor, MediaTek, Espressif Systems and other vendors of Zigbee hardware.
