As an AI Engineer, you would be responsible for:

• Designing, building and operating production AI and machine learning solutions, including data pipelines, models and inference services.
• Developing LLM-powered features using approaches such as retrieval-augmented generation (RAG), agent workflows, tool calling and structured outputs, with a focus on reliability, measurable quality and cost efficiency.
• Delivering end-to-end machine learning workflows on Databricks, from data preparation and feature development through training and evaluation to batch and real-time deployment.
• Maintaining quality in production through versioning, evaluation, monitoring and drift detection, and supporting the investigation and recovery of solutions when issues arise.
• Collaborating with Product, Engineering, Commercial and Operations teams to translate business needs into scoped technical requirements, measurable success criteria and realistic delivery plans, including relevant data and privacy constraints.
• Contributing to governance-ready data and AI practices covering quality, lineage, access, security, GDPR and responsible AI, including relevant EU AI Act requirements.
• Working with technical and non-technical stakeholders to explain trade-offs and model limitations, gather feedback and help prioritize improvements based on their potential impact.
• Reviewing peer contributions, documenting and sharing knowledge, developing reusable components and helping improve our shared libraries and Data & AI platform tooling.

We would like you to have: 

• A degree in Computer Science, Data Science, Statistics, Mathematics or a related field, or equivalent practical experience, together with strong English communication skills at C1 level.
• 3–5 years of hands-on experience in Machine Learning Engineering, Applied AI, Data Science or a related field, including experience taking at least one AI or machine learning solution from prototype into production.
• Strong Python skills and practical experience with machine learning frameworks such as scikit-learn, PyTorch or equivalent technologies, along with solid SQL and warehouse or lakehouse experience.
• Hands-on experience with Databricks, including several of the following: Spark, Delta Lake, Unity Catalog, MLflow or Workflows.
• Experience evaluating and deploying models beyond the experimentation stage, with an understanding of monitoring, reliability and production quality.
• Familiarity with LLM application patterns such as RAG, prompt workflows and evaluation, as well as cloud platforms, ideally AWS, and CI/CD practices for machine learning, or the foundations and motivation to develop further in these areas.
• The ability to independently deliver well-defined AI/ML tasks, collaborate with product and business stakeholders and explain technical trade-offs, model behavior and limitations to non-technical audiences.
