AI/HPC Network Development Engineer - Networking

<div class="content-intro"><h3><strong><span style="font-family: arial, helvetica, sans-serif;">About xAI</span></strong></h3> <p><span style="font-family: arial, helvetica, sans-serif;">xAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. </span><span style="font-family: arial, helvetica, sans-serif;">Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. </span><span style="font-family: arial, helvetica, sans-serif;">We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. </span><span style="font-family: arial, helvetica, sans-serif;">All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.</span></p> <p> </p></div><h2><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">About the Role</span></h2> <p><span style="font-size: 12pt; font-family: arial, helvetica, sans-serif;">xAI was first in the world to build a 100k GPU cluster on an ethernet network and then did it again in 92 days, floors, walls and all. We need an engineer with deep experience in RoCEv2 that can develop at hyper scale while optimizing performance and availability. </span></p> <p><span style="font-size: 12pt; font-family: arial, helvetica, sans-serif;">xAI is building at a furious pace with the latest hardware to help people understand the universe. To make the next significant leap forward, we need to own our own destiny by understanding our current network performance and availability and then optimize it to our training models and how we execute customer inference queries. You will spend most of your days deep inside NCCL, building metric dashboards and tweaking configurations to ensure no performance is left on the table. You will help design the next iteration of our backend and front-end networks that will allow us to seamlessly build-out new GPU infrastructure with little to no engineering assistance. </span></p> <p><span style="font-size: 12pt; font-family: arial, helvetica, sans-serif;">There will be a significant amount of travel to Memphis for building more capacity as well as participating in a team on-call rotation and helping on other scaling and maintenance efforts. This will become easier as we build out the team and engineers contribute to deployment and operations frameworks to remove repetitive tasks.</span></p> <h2><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">Location</span></h2> <p><span style="font-size: 12pt; font-family: arial, helvetica, sans-serif;">We have 2 openings, one based in Palo Alto, California and the other in Dublin, Ireland. There will be significant travel expected to Memphis, Tennessee for data center buildouts and to the head office in Palo Alto for team collaboration.</span></p> <h2><span style="font-family: arial, helvetica, sans-serif; font-size: 14pt;">Required Qualifications</span></h2> <ul> <li style="font-size: 12pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 12pt; font-family: arial, helvetica, sans-serif;">A minimum of 10 years designing and operating large scale networks with 5 years in the ethernet AI/HPC space.</span></li> <li style="font-size: 12pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 12pt; font-family: arial, helvetica, sans-serif;">Deep understanding of congestion control on ethernet with Infiniband an added bonus.</span></li> <li style="font-size: 12pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 12pt; font-family: arial, helvetica, sans-serif;">Deep understand ...
