Senior GenAI Engineer — Remote, Production AI Orchestration

Social You, S.L.; España; A distancia; EUR 90.000 - 140.000; Jornada completa

Descripción de la vacante

Social You, S.L. is seeking a Senior GenAI Engineer to design scalable AI workflows and multi-model orchestration for a cutting-edge coverage analysis platform. You will build end-to-end agentic systems, structure data with Pydantic, and optimize prompts and token usage.

The role requires 5+ years of Python development and 2+ years delivering production systems powered by LLMs, with hands-on LangGraph/LangChain experience and deep LLM fluency. This is a remote role with global collaboration.

Formación

• 5+ years of Python development with strong software engineering fundamentals.
• 2+ years building production systems powered by Large Language Models.
• Hands-on experience with LangGraph or similar agentic/orchestration frameworks (LangChain, etc.).
• Deep expertise with Pydantic for structured data modeling and validation.
• Strong understanding of LLM capabilities, limitations, prompt engineering, and evaluation methodologies.
• Production experience with async Python (asyncio, concurrent request handling).
• Ability to design and implement complex system architectures with minimal guidance.

Responsabilidades

• Architect GenAI workflows and design end-to-end agentic systems using LangGraph.
• Build robust LLM orchestration with tools like LiteLLM, managing multi-model strategies and cost efficiency.
