About the Role

Together AI operates one of the world's largest GPU fleets, and the Infra Agent Systems team develops the software to automate this infrastructure. We build production AI agents for diagnosing hardware failures, investigating incidents, correlating signals, and automating operational workflows. We also develop the platform these agents run on, including knowledge graphs, retrieval systems, orchestration frameworks, and developer tooling. This role offers the chance to work at the intersection of AI agents, distributed systems, infrastructure, and automation, solving complex engineering problems with significant production impact and shaping the future of autonomous infrastructure.

Responsibilities

  • Design and build production AI agent systems that diagnose, investigate, and remediate infrastructure issues across one of the world’s largest GPU fleets.
  • Build the distributed services, orchestration framework, knowledge graph, and retrieval systems that power infrastructure agents.
  • Develop fleet intelligence systems that combine telemetry, infrastructure state, operational knowledge, and historical incidents to help agents make better decisions.
  • Integrate with observability, incident management, ticketing, fleet inventory, source control, chat, and internal infrastructure systems through well-designed APIs.
  • Own services end to end, including architecture, implementation, testing, deployment, observability, and production operations.
  • Improve agent performance through evaluations, retrieval improvements, better tools, and production feedback loops.
  • Turn what agents learn in production into reliable, reviewed software and automation.

Requirements

  • 5+ years of experience building production backend systems, distributed systems, or infrastructure platforms.
  • Strong systems design skills and experience owning significant systems from design through production.
  • Depth in AI agent systems, orchestration, tool use, evaluation, or grounding.
  • Depth in knowledge graphs or graph data modeling.
  • Depth in search, retrieval, ranking, RAG, or semantic search systems.
  • Strong backend engineering experience, including API design, service boundaries, data modeling, and integrations across complex systems.
  • Experience with Kubernetes, GitOps such as ArgoCD, infrastructure-as-code, and cloud platforms.
  • Comfortable working across languages such as Go, TypeScript, Python, or Rust.
