Middle Electronics Engineer

About the Role

This role requires in-depth knowledge of electronics, microcontroller firmware, and PCB design. You will be involved in both R&D and service activities.

Key Responsibilities

• Deliver technical ideas from initial analysis and solution selection through independent implementation, testing, and practical application.
• Integrate existing components (cameras, communication systems, UPS, sensors, controllers, etc.) into complete systems.
• Perform hands-on PCB bring-up, including initial power-up, power supply and interface verification, troubleshooting, and fault resolution.
• Reverse-engineer electronic systems and PCBs, including cases where complete technical documentation is unavailable.
• Perform hands-on electronics work, including schematic analysis, soldering, PCB modifications, and debugging.
• Work with battery systems and BMS (Li-ion / LiFePO4), including configuration, diagnostics, repair, and integration.

Strong preference will be given to candidates with personal or professional hands-on hardware projects.

Qualifications

• 3 years of experience in electronics development or in-depth hardware analysis (circuit design, PCBs), including practical experience in PCB bring-up and reverse engineering without documentation.
• Proficiency in using laboratory equipment, including oscilloscopes, logic analyzers, multimeters, and laboratory power supplies.
• Hands-on experience in soldering, assembling, and modifying electronic PCBs.
• Experience developing and analyzing microcontroller firmware and working with digital interfaces and communication protocols (SPI, I2C, UART, CAN, Ethernet).
• Experience with CAN bus analysis and CAN diagnostic tools.
• Solid understanding of digital and analog circuit design.
• Ability to read, analyze, and modify electrical schematics.
• Hands-on experience with battery systems and a solid understanding of their architecture, including Li-ion / LiFePO4 batteries, BMS, cell balancing, protection, measurement, and communication interfaces.
• Ability to identify and troubleshoot hardware and software issues at the signal, power supply, interface, and component levels.
• Ability to prepare clear technical reports and support recommendations with actual measurement data.
• Technical English proficiency sufficient to work with documentation and supplier information.
• Willingness to travel for business purposes.

Will Be a Plus

• A valid driving licence, manual transmission.
• Experience with Raspberry Pi / Embedded Linux.
• Solid knowledge of at least one microcontroller platform: STM32, ESP32, or Arduino-compatible MCUs.
• Experience with KiCad / Altium Designer.
• Experience working with cameras and video interfaces: USB, Ethernet, etc.
• Knowledge of DC/DC converters and power electronics.
• Experience with robotics, motor controllers, and sensors.

Please note: You do not need to meet every single requirement to apply. We welcome motivated candidates who are eager to grow into the role and develop their expertise further.
