Firma i stanowisko

Senior Embedded Firmware Engineer position at EER Poland focusing on RTOS, communication, critical systems, and secure embedded systems. The role involves working on low-level firmware and communication with backend systems within embedded security and communication modules. The project includes two main MCU units: a low-power safety/power controller (nRF5340 or similar) and a communication/application controller (i.MX RT1061 or similar).

Wymagania

Strong knowledge of C/C++ in embedded systems
Experience working with MCUs (e.g., STM32, nRF, ESP32)
Familiarity with communication protocols: UART, SPI, I2C, and BLE or other wireless
Experience in designing embedded systems architecture, not only implementation
Ability to debug HW/SW systems (JTAG, SWD, system logs)
Experience designing interfaces and APIs between system components

Nice to have:

Experience with secure embedded systems (device identity, secure update concepts, integrity, tamper resistance)
Experience with OTA and bootloaders (rollback, recovery, update safety)
Knowledge of RTOS systems (e.g., FreeRTOS, Zephyr)
Experience with device-to-backend communication (WebSocket, MQTT, REST)
Background in automotive or industrial embedded systems
Knowledge of provisioning, fleet management, and BLE onboarding systems

Nice to have (not required):

Experience with OCPP
Experience with Zephyr RTOS
Experience with embedded Linux (Buildroot, Yocto)

Obowiązki

Develop firmware for security components and communication modules
Design and improve communication between two MCUs
Work with real-time logic, state machines, and error handling
Create and maintain hardware drivers (UART, SPI, I2C, GPIO)
Design and develop wireless communication systems (BLE onboarding, provisioning, data exchange)
Ensure stable backend communication via OCPP over WebSocket or similar device-cloud protocols
Work on OTA updates, rollback, recovery, and update security
Perform low-level debugging using tools such as JTAG, SWD, and logic analyzers
Design APIs and communication layers between system modules

Benefity

100% remote work
B2B contract with salary up to 8,000 EUR net per month
Flexible working hours
Collaboration with an experienced system/firmware team
Real influence on product architecture and development direction
