Barcelona, Provincia de Barcelona, España Capitole Jornada completa
Capitole keeps growing — and we want to do it with you We're looking for an Machine Learning Engineer #MLEto 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.
* 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).
* An individual training budget of €1,200 for whatever you choose: events, books, certifications or courses.
* Monthly check-ins with your team for continuous feedback.
* Flexible

working hours
to balance your professional and personal life.
* Flexible compensation: meal, transport and/or childcare vouchers.
* Discounts on major brands for employees (Club Capitole). Capitole | Empowering people, unlocking technology innovation
