Principal Scientist – Surface Biology Early Validation Lead
What you will do
Let’s do this. Let’s change the world. We are building a high-throughput surface biology capability to enable early validation and characterization of membrane protein targets across Therapeutic Areas. This work focuses on generating high-quality experimental data to deepen understanding of target biology and support downstream therapeutic exploration.
We are seeking an experienced Principal Scientist to lead a team focused on early-stage experimental strategies and assay development to evaluate membrane protein expression, localization, and internalization. In this role, you will guide the development and application of cell-based and quantitative assays, working closely with cross-functional partners to ensure data are robust, scalable, and aligned with discovery needs.
You will operate in a highly collaborative environment, partnering with Therapeutic Area teams and platform functions to deliver biologically relevant insights that support target evaluation.
Provide scientific and operational leadership for a team supporting early target validation
Lead the design and execution of cell-based and quantitative assays to discover and evaluate membrane protein biology
Establish robust, scalable workflows to support multiple discovery programs
Interpret experimental data and communicate clear, actionable insights to project teams
Partner with cross-functional stakeholders across the Discovery Sciences and Advanced Technologies and AI organization, Therapeutic Discovery, and Therapeutic Areas.
Collaborate across teams to integrate data and inform target evaluation and prioritization
Identify and implement new technologies to enhance assay robustness and throughput
Mentor and develop scientists, fostering a culture of rigor, collaboration, and accountability
