Director, US Business Aligned Data Science (Secondment - 6 Months)

Pfizer•New York City, NY

8h•Hybrid

About The Position

This secondment offers a Director-level individual contributor the opportunity to professionally grow within the US Business Aligned Data Science (BA-DS) team. This experience is well suited for a current data scientist or analytic-minded individual looking to expand their technical and methodological expertise into more applied analytic decision-making for commercial partners. The successful candidate is expected to carry out the functions of the BA-DS team, which are rooted in translating key commercial business questions into advanced analytic insights. Strong emphasis is placed on applying data science principles to the business problem, rigorously documenting the end-to-end analytic pipeline, purposely communicating with stakeholders, and delivering effective presentations appropriate to the target audience. The secondment is focused – but not limited – to high-impact workstreams that are anchored around two core capabilities of the BA-DS team – Dynamic Targeting and Dynamic Content. These workstreams provide the opportunity to leverage technical leadership in building and optimizing data models and processes, while also collaborating with Commercial and GCA stakeholders. Other projects may also be prioritized given specific needs and timelines.
