xAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. 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. All engineers are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.
About the Role
We are training some of the largest models in the world on the latest hardware across multiple environments. To do this reliably at xAI’s pace, we need engineers who have battle-tested experience keeping massive distributed infrastructure up and running 24/7, including on-prem and cloud-based infrastructure. This is a joint xAI/X role: you will own 24×7 reliability for the world’s largest GPU training superclusters and one of the highest-QPS production systems on the planet (X).
You will own the availability, performance, and evolution of xAI’s core compute, storage, and networking infrastructure. This is not an ops-only role — strong coding is a hard requirement. You will design, implement, and ship systems software, automation, and tooling in Python and/or Rust that directly impact training throughput and cluster utilization. You will be expected to participate in a team on-call rotation and to contribute to ushering xAI into the next generation of infrastructure management across multiple data centers and cloud environments.
Responsibilities Will Include
Location
Work will be in-office based out of either Palo Alto, California or Dublin, Ireland.
Travel to our Memphis office is both an expectation and requirement for this role.
