About the role

Key responsibilities & impact

Monitor, maintain, and optimize the agentic infrastructure running on LangChain / LangSmith / LangGraph
Manage container-based deployments and ensure stability across environments
Build and own CI/CD pipelines for agent and model deployments
Set up and maintain observability — tracing, alerting, and performance dashboards for LLM-based systems
Support MCP server integration as the client-side team ships new components
Identify and resolve latency, cost, and reliability issues before they become production incidents
Work closely with the client's MCP technical lead — small team, no bureaucracy, your infrastructure decisions are immediately visible

Requirements

What you’ll need

Strong DevOps fundamentals in practice — you own deployments, not just contribute to them.
Container orchestration (Docker + ECS/Fargate or equivalent), GitHub Actions for CI/CD, AWS (ECS, RDS, S3, CloudWatch), and MCP protocol familiarity are part of your daily work
Hands-on production experience with LangChain, LangSmith, and/or LangGraph — not course projects or prototypes
LLM infrastructure thinking — you understand token cost, latency tradeoffs, rate limits, and how to monitor them in production
Comfortable working autonomously in a small team without daily hand-holding
Near-native English — daily async communication with a US-based technical lead and client stakeholders
