- Develop communication stacks:
- RS485/Modbus RTU
- RS232
- MQTT, TCP/IP, UDP
- Work with FreeRTOS for multitasking & low-power firmware.
- Implement bootloaders, OTA update flows & firmware versioning.
- Debug firmware using SWD/JTAG, logic analyzer, DSO traces.
- Optimize code for performance, low power, and reliability.
What You Should Bring
- 3–5 years experience in embedded firmware development.
