System Engineer

Texas Instruments•Dallas, TX

About The Position

This role is in the HVDC datacenter product line where we are working on designing the chips needed for the next generation of AI datacenter power supplies. This is a high visibility and high growth product area. The product line develops both the primary side 400V GaN power stages as well as the secondary low-voltage synchronous rectifiers for 800V to low-voltage LLC converters. You will own system-level definition and application support for GaN power FETs and SR FETs targeting datacenter power conversion. This is a technical individual contributor role with direct customer engagement — you sit between GaN/Si design and the hyperscaler/ODM engineers who deploy our devices in production hardware. At TI, System Engineers work to identify ideal roadmap opportunities for a business and are responsible for defining new products and platforms based on market opportunity. To do this, they leverage strong technical knowledge of our existing portfolio, deep understanding of the technologies, standards and protocols within an industry or end equipment, and an ability to engage with customers and translate their requirements into technical specifications that will solve their problems. Systems engineers also partner closely with marketing and applications engineers, as well as design teams, to ensure our roadmap is both meeting customer and market requirements and is technically optimized and manufacturable at a price and cost point that makes sense for the business.

Requirements

Bachelor's degree in Electrical Engineering, ECE or related engineering degree
4 + years of relevant Systems engineering experience with power conversion
