Legrand - Embedded Software Engineering Manager - Thane

Role & responsibilities

• Work on a variety of embedded platforms, including battery-powered, event driven SoCs and general-purpose microcontrollers running real-time operating systems (FreeRTOS, Zephyr) and Embedded Linux.

• Contribute to the design, development, and validation of embedded software, from low-level drivers to application logic and communication stacks (Zigbee, Wi-Fi, BLE).
• Ensure seamless integration of IoT protocols (MQTT, HTTPS, TCP/IP, Modbus/RTU, Modbus/TCP) for device communication and interoperability.
• Ensure full compatibility and reusability frameworks by applying shared architecture principles and coding standards.
• Debug, analyze, and optimize embedded software for reliability, performance, and energy efficiency.
• Participate in cross-site initiatives to improve common frameworks, reduce technical debt, and strengthen software modularity and maintainability.
• Actively contribute to PoCs or technology evaluations in coordination with European teams to explore innovative embedded platforms or new radio protocols.
• Produce and maintain clear, structured technical documentation (architecture notes, module descriptions, integration guides, and API references) to ensure knowledge continuity and alignment across sites.

Preferred candidate profile

• Bachelors or Master’s degree in Computer Science, Electronics, or related field.

• 12–15 years of Embedded development experience, including at least 4 years in a managerial capacity.

• Programming Languages: Strong proficiency in C; basic scripting in Shell and Python for automation and tooling.

• Microcontrollers: Experience with ARM Cortex-M architectures or similar MCU families.

• Communication Protocols: Proven experience with Wi-Fi, MQTT, HTTPS, TCP/IP, Modbus/RTU, Modbus/TCP, TCP/IP, Zigbee, and IEEE 802.15.4 stacks; exposure to BLE is a plus.

• Exposure to cloud integration (Azure IoTHub, or similar).

• Embedded Systems: o Development for resource-constrained devices with memory and energy limitations. o Solid understanding of low-level software, boot sequences, and peripheral interfaces (SPI, IC, UART).

• Tools & Techniques: o Proficiency in debugging tools, oscilloscopes, and logic analyzers is a plus. o Experience in modular design and code optimization for real-time and event-driven systems. o Familiarity with CI/CD pipelines and version control systems (Git, GitLab CI).

• Linux Environment: Comfortable working in Linux-based environments, as all our build systems, toolchains, and automation workflows are developed and validated on Linux.
