We're looking for an AI/ML Engineer to join a global leader in HR technology — a team building Generative AI assistants used across global markets.


This is a hands-on engineering role , where focus is shipping GenAI/NLP models to production in Python , working shoulder-to-shoulder with MLEs inside a lean 5–6 person squad across 3–4 projects. If you code your ML solutions yourself rather than leaning on out-of-the-box AutoML tools, and you like owning the technical solution end-to-end, this is for you.


What you'll find here:

  • Building production-ready GenAI/LLM features — chatbot assistants and NLP systems, from prototype to production.
  • Writing structured, quality Python with real engineering discipline: PR practices, Git, CI/CD, Docker .
  • Designing end-to-end NLP pipelines — data processing, model development, evaluation, deployment.
  • Getting hands-on with LLMs, embeddings and modern GenAI tooling (OpenAI, AWS Bedrock).


We're looking for someone who:

  • Brings 3–5 years of experience building production features/systems with AI/ML .
  • Writes advanced, production-grade Python — not notebook scripting.
  • Has worked on real NLP / GenAI / LLM projects and can explain them in depth — embeddings, evaluation metrics beyond accuracy, how they assessed system performance.
  • Thinks like an ML engineer : moves models to production, understands the full pipeline, applies solid coding practices (Git, PR, CI/CD, Docker ).
  • Knows their way around ML libraries (scikit-learn, PyTorch) and data processing (pandas).


Nice to have:

  • Experience with Databricks.
  • Familiarity with AWS infrastructure (S3, Lambda, Bedrock).
  • Understanding of data augmentation, bias and training pipelines .
  • A Software Engineering background with a recent move into AI/ML.


Location: Barcelona. (Hybrid: 1–2 days in the office).

Language : English C1 (Fluent, all team communication is in English).

  • Private health insurance fully paid by Capitole.
  • Flexible compensation: meal, transport and/or childcare vouchers.
