Applications Engineer - UCD

Job Description:

We are seeking an experienced and customer-focused Applications Engineer to support the design-in and adoption of our UCD family of digital power controllers. The ideal candidate will have strong expertise in digital power control topologies, embedded firmware, and system-level debug, with the ability to translate customer requirements into working solutions. This role requires close collaboration with design, marketing, and field sales teams to enable customers building mission critical data centres, AI servers, and a wide array of Industrial applications.

Key Responsibilities:

• Customer design support: Provide technical guidance to customers on the design, configuration, and firmware development of systems using TI ASM UCD devices such as the UCD3138/UCD4138, across applications like Power Factor Correction (PFC), DC/DC converters, and other digital power topologies.
• Reference design development: Design, build, and validate reference designs, evaluation modules (EVMs), and demo boards that showcase UCD capabilities and accelerate customer adoption.
• Firmware and GUI tools: Develop and customize firmware, configuration tools, and GUIs (e.g., Fusion Digital Power) to simplify customer evaluation, tuning, and deployment of UCD-based designs.
• System bring-up and debug: Support customers with board bring-up, system integration, and troubleshooting of hardware, firmware, and communication interfaces (e.g., PMBus, I2C, SPI).
• Lab characterization: Use lab equipment such as oscilloscopes, power analyzers, and logic analyzers to characterize system performance, validate control loop stability, and resolve customer-reported issues.
• Pre- and post-sales support: Respond to customer technical queries via E2E forums, service requests, and direct engagement, including both pre-sales design consultation and post-sales production support.
• Cross-functional collaboration: Work closely with design, test, marketing, and field sales teams to relay customer feedback, influence roadmap decisions, and support new product introductions (NPI).
• Documentation and collateral: Create and maintain technical reference manuals, datasheets, application notes, user guides, FAQs, and training materials to support customer self-sufficiency and broaden product adoption.
• Continuous Improvement: Participate in design reviews and contribute to improving applications engineering tools, processes, and support methodologies.

Required Skills and Qualifications:

• 3+ years of industry experience in applications engineering, systems engineering, or embedded firmware development.
• Bachelor's or master's degree in Electronics/Electrical/Computer Engineering, or a related field.
• Strong proficiency in embedded C/C++, with the ability to read, debug, and modify firmware for digital power controllers.
• Experience with industry-standard communication protocols like PMBus, I2C, and SPI.
• Experience with TI's Code Composer Studio (CCS), IAR, Keil and other relevant development and debug tools.
• Familiarity with scripting languages like Python, JavaScript and ability to automate characterization, test, and support workflows.
• Strong customer-facing communication skills, with the ability to explain complex technical concepts clearly to customers of varying expertise.
• Direct, hands-on experience with TI's UCD digital power controller family or Fusion Digital Power GUI will be an added advantage.
• Deep understanding of digital power control theory and common topologies (PFC, buck, boost, LLC, etc.).
• Basic understanding of signal processing and experience using model-based development tools like MATLAB and Simulink will be a definite plus.
• Ability to read and interpret schematics and datasheets, with experience in hardware-software interaction and board-level debugging.
• Proficiency in using standard lab equipment and debugging tools.
• Strong analytical and problem-solving skills, excellent communication abilities, and a collaborative, customer-centric mindset.
