About the Role

At Together AI, you’ll build and operate one of the world’s largest GPU fleets used for frontier model training and inference. This isn’t a traditional infrastructure role—we’re looking for engineers who love building systems, automating everything, and solving problems at massive scale.

If you enjoy writing software more than clicking dashboards, obsess over eliminating manual work, and want to build infrastructure that manages tens of thousands of GPUs autonomously, we’d love to talk.

Responsibilities

Design and build fleet automation systems that provision, validate, deploy, upgrade, repair, and retire GPU clusters with minimal human intervention.
Build AI Infrastructure Agents that automate deployment, root-cause failures, incident triage, and autonomous remediation.
Develop Fleet Intelligence platforms that continuously monitor hardware health, firmware, networking, storage, thermals, and workload performance to predict failures before they impact customers.
Build software that maximizes GPU availability, utilization, performance, and reliability across thousands of accelerators.
Create automated validation systems for GPUs, InfiniBand/RoCE fabrics, NVLink/NVSwitch, storage, and distributed AI workloads.
Build internal platforms and developer tools that allow infrastructure to be managed through software—not manual operations.
Continuously improve deployment velocity, reliability, and operational efficiency through automation.
Partner closely with hardware, networking, platform, and AI teams to push the limits of AI infrastructure.

Strong systems thinking with the ability to understand problems across hardware and software.

InfiniBand or RoCE networking
Bare-metal provisioning and lifecycle management
Large-scale AI training or inference clusters
Hardware health monitoring and predictive failure detection
