About the Role
Dobu builds electronics and automation products, including home automation systems. We are looking for an engineer who works close to the hardware: someone who can read a schematic, bring up a new board, and write reliable firmware for small 8-bit 8051 microcontrollers as well as FreeRTOS applications on 32-bit microcontrollers. The engineer will own firmware from first prototype to production release and work closely with our PCB and software teams.

Main Responsibilities

Write bare-metal C firmware for 8051-family microcontrollers (e.g. Silicon Labs EFM8/C8051, Nuvoton N76E003, STC, TI CC2530).
Develop FreeRTOS-based applications in C and C++ on 32-bit microcontrollers (e.g. STM32, ESP32).
Write drivers for UART, SPI, I²C, ADC, timers/PWM, GPIO and communication modules.
Bring up and debug new circuit boards together with the hardware team.
Test firmware, write documentation and manage releases for production.

Must-Have Requirements

Degree in Electronics, Electrical or Computer Engineering (or equivalent experience).
4+ years of professional embedded firmware development in C.
At least one shipped product on an 8051-family microcontroller, written bare-metal (not Arduino-style).
At least 2 years with FreeRTOS (or a similar RTOS) in a real product.
Good C++ skills for embedded systems.
Can read schematics and datasheets independently.
Hands-on use of oscilloscope, logic analyser and hardware debugger.
Experience with Keil C51, SDCC or IAR for 8051.
Uses Git daily.
Good English communication.

Nice-to-Have

Wireless experience: Zigbee, BLE, Wi-Fi.
Home or building automation protocols: Modbus, RS-485, KNX, Matter/Thread.
Bootloader and over-the-air (OTA) firmware update experience.
Python for test tools and scripts.
PCB design experience in KiCad or Altium.

Who Is a Good Fit

Takes ownership and works independently.
Debugs problems systematically, by measuring rather than guessing.
Communicates clearly and gives regular progress updates, especially when working remotely.
Enjoys working in a small, collaborative team.

Responsibilities

Develop, test, and maintain embedded firmware for microcontroller-based systems using Embedded C and C++.
Implement and optimize real-time operating system applications, primarily FreeRTOS, ensuring reliable task scheduling and inter-process communication.
Perform bare-metal programming on 8051 microcontrollers and support firmware for STM32 and ESP32 platforms.
Interpret and analyze circuit schematics and datasheets to design and debug embedded hardware and firmware;
Utilize hardware debugging tools such as oscilloscopes, logic analyzers, and hardware debuggers to troubleshoot and resolve firmware and hardware issues.
Work with communication protocols and peripherals including UART, SPI, I2C, ADC, GPIO, timers, and PWM to ensure correct interfacing and functionality.
Use development environments and tools such as Keil C51, SDCC, IAR, and version control systems like Git for source code management and collaboration.
Collaborate remotely with cross-functional teams to define firmware requirements, timelines, and deliverables.
Analyze firmware performance and implement optimizations to ensure efficient resource utilization and power management.
Document software designs, test results, and procedures to maintain product quality and support future development.
Maintain strong problem-solving skills to independently identify issues and propose solutions during all phases of firmware development.
Stay current with emerging technologies and best practices in embedded systems and firmware engineering.
