## Description

You'll lead the data engineering workstream inside cross-functional Agile teams with Data Scientists, ML Engineers and domain experts. You'll work directly with clients, from data owners to C-level executives, and mentor junior engineers along the way.

Candidate should be based in or around Madrid and open to travel as per business requirement.

What You Will Do

 * Own technical workstreams. Design and deliver machine learning, Generative AI and agentic/autonomous AI systems from architecture through production.
 * Architect scalable data platforms. Build robust batch and streaming pipelines that are tuned for modern AI workloads.
 * Integrate GenAI and agentic frameworks into client solutions. This covers RAG pipelines, embeddings, vector databases, context construction, prompt design and output handling.
 * Design MLOps/LLMOps architectures for model management, observability, automated evaluation and retraining.
 * Lead feature engineering on complex workstreams so that data assets are reliable, reusable and ready for AI.
 * Govern and secure data. Implement access controls, PII/PHI handling, authentication and RBAC across cloud environments.
 * Make sound engineering trade-offs between quality, latency and cost. Apply evaluation, reliability and guardrail practices to AI features.
 * Mentor and raise the bar. Coach junior engineers and drive software engineering best practices across the team.
 * Partner with clients and stakeholders. Turn business problems into technical solutions and help build client capabilities.
