Agentic Core · Full-time# AI Engineer, Agentic CoreRemote · Argentina / LATAMSemi-Senior / Senior3+ years* Python* LangGraph* LangSmith* TypeScript* Postgres* AWSMany heads, one body. That is our architecture, and it is your job.Agentic Core owns everything LLM-related at Medra: conversational agents, deep agents for clients and internal teams, and the shared intelligence layer underneath them. It is the difference between an agent that solves a customer's problem and one that gets in the way.## What you will do* Build multi-agent orchestration - supervisor patterns, expert sub-agents, routing and state.* Make agents reliable at hundreds of thousands of conversations across 19 countries.* Push on evaluation: knowing whether an agent got better is central to how we ship.* Design the seams between the framework and client work, so shared patterns graduate into Core.* Shape model and provider strategy. We use several and we swap them.## What makes this hard* Agents act, not just answer. The system has to know when to act, when to ask, and when to stop.* A non-deterministic stack.



Traces, evals, guardrails and fallbacks - small changes create surprising behaviour.* Reusable, not one-off. Client learnings have to become shared capabilities, not a pile of hacks.* Scale exposes weak architecture. Brittle state or slow tools get expensive fast at this volume.## What we are looking for* 3+ years shipping production software, with serious LLM work in the recent part of it.* Strong Python or TypeScript.* You have built agentic systems - tool-calling, multi-step workflows, autonomous decisions. Not a RAG demo.* You have operated a non-deterministic system in production and have opinions on debugging one.* Spanish fluency. You will write prompts and evaluations in Spanish.* Comfortable in ambiguity. No specs, just problems.## Nice to have* Evaluation frameworks - LangSmith or anything else.* Voice agents, telephony, latency work.* WhatsApp Business API or messaging platforms at
