Project Brief

We're building out a Model Context Protocol (MCP) infrastructure for a mid-market US software company that's moving fast into agentic AI. This is a new, independent engineering team — separate from existing projects — building from the ground up. Your role has a strong DevOps lean: keeping the MCP infrastructure healthy, observable, and scalable as agents and tools get added. You'll own deployments, pipelines, and production stability. The title is adaptable — what matters is the function: someone who can hold the technical ground on infrastructure while the team builds.

Must-Haves

- 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

Nice to Have

- LangSmith tracing and evaluation features — setting up traces, running evals, interpreting results




- Experience collaborating directly with a client‑side senior engineer — comfortable integrating into an established technical dynamic and contributing without needing to redefine it
- Familiarity with observability tooling beyond CloudWatch — Datadog, Grafana, or similar

What You Will Do

- 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 deploymentsSet 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

Why This Could Be Your Next Big Move

- Infrastructure that actually matters — You're not maintaining a toy. This is a production agentic system with real users, real costs, and real consequences when things break.
- Observability as a craft — LLM systems fail in non‑obvious ways. You'll build the tooling that makes invisible problems visible before the client notices them.




- Direct access to the technical decision‑makers — Small team, no bureaucracy. Your work is immediately visible to the client's lead engineer and a senior technical advisor
- MCP is the frontier — Model Context Protocol is where enterprise AI is heading. You'll have production experience on it before most engineers have even read the spec.

Benefits & Compensation

- $4000 - $5000/month — paid in USD, bi‑weekly via Deel
- US Eastern Time hours (EST) — Monday to Friday, 9:00 AM–6:00 PM EST
- Fully Remote — work from anywhere in Latin America
- Long‑term contract — starting with a 6‑month contract, with potential to extend
- Paid PTO — accrual begins after 3‑month trial period
- Referral Program — earn a bonus for referring talent that gets hired
