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 global 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.

Por favor, verifique que tiene el nivel de experiencia y las cualificaciones adecuadas leyendo la descripción completa de esta ocasión a continuación.

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.
