Responsibilities (What he/she will do after joining UI)

• Design, develop, and debug real-time embedded firmware for IoT systems, including gateways, lighting control, and environmental monitoring and control solutions.

• Maintain, optimize, and improve firmware for existing RTOS-based devices.
• Collaborate cross-functionally with BSP, HW, ID, Backend, Mobile, FE, PM, and PA teams to deliver high-quality products.
• Contribute to system-level architecture decisions for multi-module communication
• Document software architecture, tuning methods, and test results.
• Perform code reviews, ensuring best practices in coding standards.
• Participate in troubleshooting and root-cause analysis for firmware issues.
• Collaborate with QA and manufacturing teams for production firmware validation, factory firmware, and calibration procedures.
