Senior AI Agent Engineer - Production-Grade Backend

IFS; Madrid; Presencial; EUR 70.000 - 95.000; Jornada completa

Descripción de la vacante

IFS in Madrid, MD, ES is seeking a Senior Software Engineer, AI Agents to build the AI-driven backend powering enterprise workflows on site in Madrid. You will develop the session and memory model, retrieval, and agentic flows for multi-step work.

You will implement multi-tenant SaaS capabilities, ensure secure integration with API gateways, and optimize for latency and cost while advancing GenAI features for customers worldwide.

Formación

• Experience with S2S integration using n8n, Temporal, MuleSoft, Apache Camel, or Boomi.
• Proficient in Go and Python for production backends.
• Experience building multi-tenant SaaS and AI-native products.
• Experience with GenAI, RAG pipelines and agentic systems.
• Familiar with AI frameworks like LangChain, Pydantic AI, MCP.
• DevOps experience with Docker, Kubernetes, CNCF, CI/CD.
• Experience with API gateways (Kong, Tyk) in production.
• Focus on latency and cost efficiency in AI services.
• Preference for specification-driven development.
• Curiosity for new tech; up-to-date with GenAI developments.

Responsabilidades

• Build the session and context spine: persistence, resumption, hand-over with the reasoning trail intact, and context resolved from a person's identity and entitlements.
• Build retrieval and grounding across structured records and documents, at a cost and latency the product can afford.
• Build document intelligence over manuals, engineering drawings, certification directives and contracts, extracted and citable.
• Build the agentic flow runtime: multi-step work with tools, and the rules that decide when a human is asked rather than told.
• Handle speech and images as first-class input alongside text, so the same request works dictated in a plant room or photographed at an asset.
• Build the evaluation harness, and treat it as the gate on every claim we make about autonomy.
• Build the language interface over our scheduling and optimisation engines, expressing trade-offs in the customer's own terms.
• Build the security layer with our security team: resistance to prompt injection, personal data handling, guardrails, audit and data residency.
