Software Engineering Specialist

Barcelona (Only EU Visa Holders)

We are looking for the strongest Senior Backend Engineer (Node.js) in the ecosystem. This is not a generic “backend role”.

This is systems design at scale : distributed architectures, agent orchestration, real-time data pipelines, context engineering, agentic memory, advanced RAG, high-performance APIs, and direct collaboration with AI / ML teams to push models into production.

Node.js + Typescript

Cloud-native engineering (AWS / Azure)

Docker, Kubernetes, Terraform

PostgreSQL & distributed systems

Compensation : there is no salary cap.

If you're Senior / Staff level and want to build core systems you don’t get to touch in a normal role, message me.
