Senior Ai Architect

Anywhere within Spain, Spain
We are looking for a hands-on Agentic AI Architect to define and build AI agent-based solutions for our projects and our clients. You will spend most of your time designing and guiding, and the rest building: you will define the architecture and also help the team to build it, from the first prototype to production.
You will lead our AI line within the company. You will work side by side with our engineering and project teams, who bring deep knowledge of the telecom domain, and together you will decide how to apply AI to our sector and our projects. You will also help our sales and project teams to shape offers, take part in client conversations and explain your technical decisions in a clear way. Telecom experience is not required: you will learn the domain with a team that knows it very well.
What You'll Work On
Define how we apply AI to the telecom sector: assess and prioritize use cases and support proposals and RFPs
Design end-to-end architectures, from data ingestion to automated actions
Define agent responsibilities, boundaries, autonomy levels and interaction models (single vs. multi-agent)
Design safe execution mechanisms: guardrails, approvals, policy enforcement and rollback
Build and implement solutions based on LLMs and AI agents, from architecture to working code
Build RAG-based knowledge systems using internal documentation, procedures and operational data
Work with streaming and real-time data pipelines at high volumes
Set up how we evaluate, monitor and improve AI solutions in production
Take part in client meetings and technical workshops
Share knowledge and good practices with the team while working on the same projects
Requirements
6+ years of experience in data engineering, ML or AI engineering, including experience as a technical reference or architect in projects
Recent experience (last 1-2 years) taking to production solutions with LLMs, RAG or AI agents
Practical experience with at least one agent framework (LangChain, LangGraph or similar), tool/function calling and vector databases
Strong knowledge of machine learning and solid experience designing and deploying AI/ML systems
Experience working with large data volumes, ideally in streaming or real-time environments
Good coding skills (Python) and familiarity with cloud-native architectures and AI/ML platforms
Strong communication skills: comfortable talking to clients, presenting ideas and explaining technical topics to non-technical people
