Introduction to role:

Are you the hands-on AI builder who turns sophisticated governance into code and ships production systems that stand up to regulators, auditors, and real users? Can you move from idea to working proof-of-concept in days, then mature it into a resilient, governed application that powers how a general business hires, contracts, spends, and stays compliant?

Based in Barcelona, you will be the technical authority within a high-impact squad, partnering closely with engineering leadership, enterprise technology, data engineering, legal, security, and functional teams across HR, Finance, Procurement, Legal, Audit, Compliance, and Business Development. Your work will deliver auditable, compliant AI from the first commit—helping colleagues operate faster and safer, and ultimately accelerating how we bring life-changing medicines to patients.

In this builder-first role, you design multi-agent architectures, build RAG pipelines over real enterprise corpora, route models across regions to respect sovereignty requirements,



and ship governed applications into live environments. You will set engineering standards by example while remaining the most prolific builder on the team.

Accountabilities:
- Technical Design and Solution Architecture: Lead the end-to-end technical design for AI solutions across enabling functions—selecting patterns, defining component boundaries, and making build-versus-integrate decisions aligned to the squad’s architectural direction.
- High-Consequence Decisions: Make and document model strategy choices (foundation models, fine-tuning, multi-provider orchestration, RAG), integration patterns, and tooling with clear rationale against product requirements and compliance constraints.
- Platform and Reuse: Identify and build shared components, reusable agent patterns, and governance instrumentation that speed delivery across the portfolio—championing platform thinking over one-off projects.
- Data Sovereignty in Code: Translate sovere
