Senior AI/ML Engineer - Research Data AI and Predictive Modeling (Vaccine R&D)

POSITION SUMMARY
Vaccines Research is seeking a highly innovative and technically accomplished AI/ML Engineering leader to accelerate the transformation of scientific data into a strategic asset for AI-driven vaccine discovery and development.
This role sits at the intersection of artificial intelligence, data engineering, and vaccine science. Embedded within Vaccines Research and supporting viral/bacterial vaccine programs, the successful candidate will lead implementation of a modern AI-ready research data ecosystem that enables advanced analytics, predictive modeling, generative AI applications, and agentic scientific workflows.
Vaccine research generates exceptionally diverse data, including antigen and pathogen sequences, immunological assays, omics datasets, imaging data, laboratory workflows, electronic lab notebooks, and study metadata. The scientific value lies not within individual datasets, but in the ability to connect, contextualize, and operationalize information across these modalities.
You will partner closely with Scientists, Bioinformaticians, Digital teams, and enterprise stakeholders to establish data foundations that make research data discoverable, interoperable, reusable, and AI-ready. These capabilities will power next-generation predictive and translational models that inform vaccine design, candidate prioritization, and decision-making across the research portfolio.
