Teams at xAI

As a Backend Engineer, you will design and maintain scalable backend systems, focusing on performance and reliability, primarily using Rust or C++. You will work with distributed systems and various databases while contributing directly to production infrastructure.

Develop and maintain the xAI API for high-throughput inference, managing model serving infrastructure, request routing, and scaling.

Design and ship high-performance, pixel-perfect iOS experiences using Swift, SwiftUI/UISKit and Combine; optimize memory/CPU/GPU; integrate high-throughput APIs or model outputs; own features end-to-end through App Store deployment; collaborate with AI researchers to deliver scalable mobile AI products.
