Position Overview

We are seeking a highly motivated and technically proficient Sales Engineer to drive complex solution sales across cutting-edge AI infrastructure markets. In this role, you will serve as the technical lead throughout the sales process, partnering with Account Managers, Product, and Engineering teams to understand customer requirements, design innovative solutions, and deliver compelling technical presentations and demonstrations.

The ideal candidate has a strong grasp of ASIC/semiconductor-level design and tradeoffs and deep, hands-on expertise in scale-up networking and interconnect technologies alongside a solid understanding of traditional scale-out networking and modern network operating systems (e.g., SONiC, EOS, Junos). You should be fluent in the xPU/NIC ecosystem and competitive offerings, and conversant in emerging scale-up/interconnect standards such as ESUN, UALink (UAL), and SUE.

You will work closely with customers to architect solutions that align with their business and technical goals, while representing their feedback internally to shape our product roadmap.

This is an opportunity to make a significant impact in a fast-paced, high-growth environment, with exposure to strategic customers, emerging technologies, and industry-shaping innovations.
