R&D Engineer – Embedded Firmware (80 - 100%) f/m/d

In this role, you will develop embedded firmware for UPS power supply systems, working across real-time operating systems, microcontroller platforms, hardware interfaces, testing, and cybersecurity compliance. You will help deliver reliable, secure, and maintainable firmware solutions in a global engineering environment.

Your responsibilities

• Develop, maintain, and debug embedded C firmware for UPS power supply systems using FreeRTOS on ARM Cortex and TI microcontroller platforms, including hardware abstraction layers and interfaces such as GPIO, interrupts, timers, and communication protocols.
• Build and execute automated and integration tests using gTest or similar frameworks, applying best practices for code quality, maintainability, and compliance with standards such as EU CRA and IEC 62443.
• Collaborate with design, testing, and cybersecurity teams to deliver reliable firmware, and use Git, build systems, and CI/CD practices to support efficient software development and continuous improvement.
• Demonstrate ownership, clear communication, and attention to detail while continuously learning and contributing within an Agile engineering environment.

Your background

• Degree in Software Engineering, Electrical Engineering, Computer Science, or a related field, with 3–5 years of embedded systems or firmware development experience.

• Strong embedded C/C++ skills; experience with Python or another scripting language is a plus.

• Knowledge of ARM Cortex, TI microcontrollers, FreeRTOS, and embedded communication protocols such as SPI, UART, I2C, RS485, Modbus, or CAN.

• Hands-on experience with hardware debugging, firmware integration, Git, build systems, and structured software development practices.

• Experience with industrial communication protocols such as Modbus, Ethernet/IP, CAN, or IEC 61850, and with HMI panels or HMI design tools.

• Familiarity with Node.js or IoT communication layers, plus understanding of power electronics and UPS architecture, including battery management, power conversion, and thermal management.
• Fluent in English and Italian language skills and Agile experience are considered a plus.
