Overview of Role:

The Accounting Manager, R&D (Non-Clinical) plays a critical, hands-on role in owning and managing R&D accruals and expense accounting for non-clinical trial activities across a global footprint (U.S., Europe, China). This role is central to ensuring R&D expenses are accurately accrued, analyzed, and supported, with close collaboration across vendors, internal project managers, and cross functional teams.

This position requires a hands-on accounting leader who goes beyond transactional accounting to critically assess R&D activity and ensure accruals accurately represent the business. Working cross functionally with R&D, vendors, and project stakeholders across the U.S., Europe, and China, this role plays a key part in supporting global audits and statutory financial reporting in a dynamic, high growth environment.
