Software Engineering Lead, eCommerce AI & Data Enablement

• Location: Barcelona, Spain

About the Job

Sanofi's Global eCommerce organization is building the digital infrastructure that connects healthcare professionals, institutions, and patients to our life-changing medicines. As Lead, AI & Data Enablement, you'll stand up and lead a new, strategically critical capability: making our entire eCommerce, Tender Management, and B2B technology ecosystem AI-ready and data-enabled.

This is a high-impact technical leadership role — not a people management position. You'll coordinate a flexible team of external freelance engineers and specialists, bringing in the right skillsets — data engineering, ML engineering, prompt engineering, analytics engineering, data science — for the right projects at the right time. You'll partner closely with Sanofi's central AI & Data teams, taking guidance on enterprise standards while owning execution within the eCommerce domain.

Main responsibilities

• Define and execute the AI & data enablement strategy — assess current data infrastructure and AI readiness, identify gaps, and build a multi-quarter roadmap balancing quick wins with foundational investments and product goals & features

• Source, onboard, and direct external freelance engineers and contractors, matching the right skillsets to the right projects and ensuring quality and delivery

• Design and implement scalable ETL/ELT pipelines, data warehousing, and observability frameworks, establishing data quality and governance practices with central Data teams

• Build and deploy production-grade AI/ML capabilities, including LLM-based tools, RAG architectures, prompt engineering pipelines, and ML models for analytics and personalization

• Create self-service dashboards and analytics that empower Product, Commercial, and Engineering stakeholders to make data-driven decisions

• Partner with Sanofi's central AI & Data teams to align on enterprise standards and tooling, contributing eCommerce use cases back to the enterprise roadmap

• Experience: 7+ years in data engineering, ML engineering, analytics engineering, or AI/ML technical leadership, with a track record of building data and AI systems from the ground up in complex, multi-stakeholder environments

• Technical skills: Strong depth across the full data and AI stack — ETL/ELT pipelines, data warehousing, analytics, ML model development and deployment, and LLM/prompt engineering

• Collaboration: Experience working in a matrixed organization, partnering effectively with centralized platform or enablement teams

• Bonus: Background in eCommerce, B2B platforms, or enterprise software is a strong plus
