Full-Stack Engineer - Spain - Remote

Our client is looking for a hands-on Full Stack AI Engineer who can take full ownership of an AI use case from concept to production. This is more than building models—you’ll design, implement, and deploy intelligent systems that deliver meaningful customer value.

You’ll work across the entire stack: from architecting analytics infrastructure, to building robust data pipelines, to developing and deploying advanced models. You’ll curate high-quality datasets, engineer features, and create AI systems capable of handling complex workflows and adapting to user context.

What You’ll Do

Design and implement intelligent, production-ready systems that go beyond a single model.
Prepare, clean, and curate high-quality datasets for modelling.
Develop and maintain end-to-end data and machine learning pipelines—from ingestion to deployment and monitoring.
Take a hands-on role in model design, training, and evaluation. You’ll explore and prototype solutions using a range of neural architectures, including but not limited to LLMs.
Design and experiment with Retrieval-Augmented Generation (RAG), Graph RAG, and related methods to enhance information retrieval and reasoning.
Quantize and optimise larger models into efficient versions suitable for on-device and edge processing when appropriate.

Our Ideal Candidate

Experience delivering complete AI components—from planning and modeling to deployment, monitoring, and iteration.
Strong Python skills and deep familiarity with ML frameworks such as Scikit-Learn, TensorFlow, PyTorch, and Hugging Face.
Hands-on experience with MLOps tools (e.g., MLflow, ZenML), dbt modeling, and working with cloud data warehouses or data lakes.
Experience building and scheduling pipelines in Airflow. Familiarity with modern data stacks such as Kafka, Spark, and cloud warehouses (BigQuery, Redshift, Snowflake). A focus on shipping systems that are robust, explainable, and usable by others.
