Senior Principal Research Scientist Engineering

About the Role

The Process Engineering team serves as a critical technical leadership function within our R&D organization, driving the development of next-generation therapeutics. This role is designed for a technical leader with a robust foundation in chemical engineering fundamentals and specialized expertise in biologics, peptides, ADC development, and genetic medicines. The position exists to bridge the gap between laboratory innovation and commercial viability, ensuring that novel modalities are developed with efficiency and scientific rigor.

In this capacity, you will act as a catalyst for cross-functional collaboration, proactively identifying process challenges across a diverse pipeline of innovation projects. Beyond managing technical execution, you will lead the identification and development of novel approaches and technologies to enhance process development efficiency. Your day-to-day involves setting project strategies, defining responsibilities, and providing leadership within a matrixed team environment to deliver specific project needs.

You will guide project teams through the full lifecycle of process development and characterization for new synthetic and large molecule assets, including toxins and cosmetic active ingredients. A key aspect of the role is addressing complex biochemical challenges—such as reactions, separations, and isolations—by applying expertise in reaction kinetics, transport phenomena, and mathematical modeling. You will also be responsible for establishing and executing research plans, leading the scale-up of laboratory processes in the pilot plant, and authoring technical documents that contribute to regulatory filings.

Culture and Leadership

We value a collaborative environment where scientific leadership is shared. As a mentor, you will strengthen the scientific brand of Process Engineering by guiding direct reports and colleagues. Success in this role requires the ability to communicate findings and recommendations effectively through multi-disciplinary interactions with organic chemists, analytical chemists, process development engineers, pilot plant engineers, drug product development scientists, program managers, and regulatory affairs specialists.
