We are looking for a Senior ML Engineer to take technical ownership of our machine learning production environment. You will lead the transition of experimental models into production‑grade services that are reliable, scalable, and cost‑effective. Your mission is to build the highway that allows our data science team to deploy models rapidly while ensuring those models are observable and fiscally responsible. You will own the entire ML lifecycle—from automated training pipelines to real‑time inference clusters—and serve as a key software engineering contributor to our AI product stack.

This is a hybrid role – three days per week in our Barcelona office.

In this role your key responsibilities will be:

• Lifecycle & Pipeline Architecture: Design and own the automated Continuous Training (CT) and deployment pipelines. Architect reusable, modular infrastructure for model training and serving, ensuring the entire lifecycle is versioned and reproducible.
