About the role

For our Advanced Analytics team we are looking for a Senior ML/AI Engineer, with a track record in applied machine learning / AI who has evolved toward agentic systems, to design, build and deploy AI agents (multi-agent + RAG) in production for Mango's business teams.

What you'll do

  • Design agent architectures: how a task is broken down, how agents collaborate (Supervisor/Subagent, Plan-and-Execute) and when a human intervenes (human-in-the-loop).

  • Build them in Python with frameworks such as LangGraph, OpenAI/Claude Agent SDK or Google ADK, on FastAPI/Pydantic.

  • Set up the RAG that feeds them: ingestion, embeddings, vector/hybrid search and agent memory; integration with corporate systems via MCP.

  • Evaluate and observe them in production: evaluation pipelines (LLM-as-Judge, RAGAS/DeepEval), tracing and cost/latency control (LangSmith/Langfuse), safety guardrails.

  • Identify use cases with the business (design, supply chain, e-commerce, customer service) and take them from idea to production.

What we're looking for

  • Technical degree: Computer Science, Mathematics, Physics, Telecommunications, Data Engineering or similar.

  • 4+ years in applied ML/AI (models in production: forecasting, classification, NLP, MLOps...), with 1-2 years working with LLMs in production.

  • Have built agents or RAG systems in production (not just POCs or courses), with some agent framework in Python.

  • Solid Python and engineering fundamentals: APIs, testing, CI/CD, Docker.

  • Cloud (AWS, GCP or Azure) and deployment of AI services.

Nice to have

  • We will value experience in: evaluation and observability of agents in production, MCP, vector databases (pgvector, OpenSearch, Pinecone...), open source contributions or publications, and experience in retail/fashion/e-commerce.

What you'll get

  • Immediate start with a permanent contract.

  • 35% discount on all our lines.

  • You will be able to receive technical training on platforms such as O'Reilly, among others, as well as in languages, and in skills for your personal development. We will support you so you can keep growing professionally and personally!

  • Referral policy, you can participate in the incorporation of talent to our teams, and we will reward you for it!

  • Free company transport from Barcelona and the Vallès to reach our head offices.

  • Physiotherapy service at the head offices, as well as a fitness room and changing rooms if you like to exercise in your free time.

  • Workshops, meetups, communities of practice, team buildings, and company meetings.

  • Flexible compensation package with tax advantages: medical insurance, training, meal discount, childcare, etc.

  • Dining room and kitchen service at the head office facilities. The company subsidizes part of the daily menu, as well as cafeteria items.

  • On-site medical service at the headquarters.

  • You will be part of a leading company in the fashion sector, dynamic, in full innovation, highly aware and taking actions toward sustainability.

  • Close, inspiring and ambitious working environment; you will work with a great team that is heading in the same direction to achieve the best results.

  • Constant opportunities for development with very varied challenges that generate learning in the workplace.

  • We offer flexible working hours (you can start between 8 and 9:30 and leave between 17 and 19:00) with intensive working days every Friday (you can start between 8 and 9:30 and leave between 14 and 15:30) and on most eves of public holidays.
