Member of Technical Staff

xAI is on a mission to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. As a member of the Human Data team, you'll be instrumental in delivering high-quality data to drive frontier model performance, working closely with post-training and AI tutor teams.

The role offers a unique opportunity to work in a flat organizational structure where initiative and excellence are rewarded. You'll be part of a small, highly motivated team focused on engineering excellence, where engineers are encouraged to work across multiple areas of the company.

Key aspects of the role include architecting and building the data collection platform, implementing end-to-end features, and establishing best practices for a world-class engineering team. You'll work with modern technologies including TypeScript, Python, Rust, React, Express, and PostgreSQL.

The company values strong communication skills and expects all team members to be hands-on contributors. The interview process is thorough and technical, consisting of coding assessments, systems design, and team presentations, all reviewed directly by technical team members rather than recruiters.

What sets this role apart is the opportunity to work on cutting-edge AI systems in a fast-paced, collaborative environment. You'll be contributing directly to innovative solutions that improve model capabilities, evaluation, safety, and alignment. The role offers competitive compensation and the chance to work in the heart of the Bay Area's tech ecosystem.
