Capitole keeps growing — and we want to do it with you We're looking for an AI/ML Engineer to join a global leader in HR technology — a team building Generative AI assistants used across general markets. This is a hands-on engineering role , where focus is shipping Gen AI/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 Auto ML tools, and you like owning the technical solution end-to-end, this is for you. What you'll find here: Building production-ready Gen AI/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 Gen AI tooling (Open AI, 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 / Gen AI / 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, Py Torch) 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). Why CAPITOLE? An individual training budget of €1,200 for whatever you
