About the Role

AI Engineer – Remote (Barcelona) | €100,000

About the Role

We are looking for a hands-on AI Engineer to own and evolve the core “brain” service that drives a cutting-edge AI product. This role spans architecture, development, optimization, and production operations of real-time, multi-agent LLM systems.

Role Overview

As an AI Engineer, you will design, build, and operate low-latency, real-time text and voice agent systems. You will be responsible for multi-agent orchestration, advanced reasoning approaches, RAG engineering, and evaluation-driven development to ensure production-grade quality and performance.

Key Responsibilities

• Design, build, and operate low-latency real-time text and voice agent systems
• Implement multi-agent orchestration patterns (planner–executor–critic, routing, shared memory)
• Apply advanced reasoning methods (ReAct, Chain-of-Thought, Tree- / Graph-of-Thoughts where appropriate)
• Lead RAG engineering with strong grounding, evaluation, and observability
• Drive evaluation-based development with monitoring, tracing, and CI / CD gating
• Ship production-grade Python services using FastAPI under strict latency and quality requirements

Minimum Qualifications

• 5+ years of experience in ML or backend engineering in production environments
• Deep expertise in Python, FastAPI, asyncio, and production observability
• Experience with low-latency text and / or voice systems (LiveKit, Pipecat, WebRTC, or similar)
• Hands-on experience with LLM systems, agent patterns, and evaluation-driven workflows
• Prior startup experience

Tech Stack Highlights

Python, FastAPI, asyncio, Redis, Postgres, vector databases, WebRTC / LiveKit, SIP gateways, Docker, Terraform, Kubernetes, OpenTelemetry, DeepEval, GCP

What We Offer

• Work on state-of-the-art real-time AI agent technology in healthtech
• Highly collaborative, senior technical team
• Fully remote role based in Barcelona
• Fun off-sites and strong developer ergonomics
