Job description

We are seeking an experienced and motivated Software engineer to design, develop and test software for our UCD family of digital power controllers. The ideal candidate will have deep expertise in embedded C/C++ programming and a strong understanding of digital power control topologies and algorithms. This role requires close collaboration with hardware and application engineers to deliver robust, high-performance solutions that powers mission critical data centres, AI Servers and a wide array of Industrial applications.

Key Responsibilities:

• Software development: Design and develop high-quality, real-time software for TI ASM UCD devices, such as the UCD3138/UCD4138, for applications like Power Factor Correction (PFC), DC/DC converters, and other digital power topologies.
• Algorithm implementation: Translate complex control algorithms for power regulation, calibration, and monitoring into efficient, low-level C code that runs on the UCD's digital power peripherals (DPPs).
• Hardware-Software Integration: Work closely with hardware design teams to integrate firmware with new power management hardware, validate system functionality, and perform board bring-up.
• Driver development: Write and maintain device drivers for the UCD's internal peripherals and external communication interfaces (e.g., PMBus, I2C, SPI).
• Debugging and optimization: Use debugging tools like JTAG, oscilloscopes, and logic analysers to troubleshoot firmware, hardware, and system-level integration issues. Optimize firmware for performance, memory footprint, and power consumption.
• Validation and testing: Develop and execute comprehensive test plans and automated test scripts to ensure the software meets all functional and performance requirements.
• Customer Support: Provide technical support to application engineers and customers, assisting with firmware-related issues and implementation guidance.
• Documentation: Create and maintain technical documentation, including design specifications, firmware architecture, and test procedures.
• Continuous Improvement: Participate in code reviews and contribute to the improvement of software development methodologies and processes.
