AI Infrastructure Engineer, pAGI

Details

The pAGI Infrastructure team builds and operates systems that make large-scale model training and evaluation reliable, efficient, and easy to run. The work spans distributed training infrastructure, inference and grading platforms, compute scheduling, and research tooling. The team partners with researchers and engineering teams to turn research needs into dependable infrastructure, improve GPU efficiency, and shorten the path from experiments to validated models.

The role involves scaling infrastructure behind training and evaluation workflows, owning projects from identifying bottlenecks and designing solutions through deployment and operation. The work combines distributed systems engineering, performance optimization, and close collaboration with researchers.

Responsibilities

• Build and operate infrastructure for large-scale training and evaluation, improving reliability, throughput, and resource efficiency.
• Develop shared inference and grading platforms with automated capacity management, health monitoring, and performance visibility.
• Improve compute scheduling and resource allocation to reduce idle GPU time and help workloads recover quickly from failures.
• Diagnose bottlenecks across training, inference, and orchestration, and work across teams to improve end-to-end performance.
• Build self-service tools, automated validation, and observability that help researchers launch experiments, diagnose issues, and compare results with less manual intervention.

Requirements

• Interest in the potential of personal AGI and in building the infrastructure that enables it.
• Strong software engineering fundamentals and experience building or operating large-scale distributed systems.
• Experience in ML infrastructure, inference systems, GPU performance, or infrastructure tooling.
• Ability to take ownership of open-ended problems and work independently.
• Enjoyment of debugging across system boundaries and using measurements to guide improvements in performance and reliability.
