About The Position

Reporting to the SVP, Human Resources and Talent Acquisition, the Senior Director, HR Business Partner (HRBP) for the Commercial Organization is a strategic leadership role responsible for partnering closely with the Chief Commercial Officer (CCO) and Commercial Leadership Team to build, scale, and optimize a high-performing commercial function. This individual will serve as a trusted advisor, aligning people strategies with business objectives to support the successful transition to and execution of commercialization, including both corporate and field-based teams. This role will be hired in advance of commercial scale-up and top-line data, within a lean and evolving organization. While the primary focus is supporting the Commercial function, the Senior Director will initially operate as a broad HR Business Partner across the enterprise, flexing support across Clinical, Technical Operations, and G&A as needed. This role requires comfort operating in a highly dynamic, resource-constrained environment, with the ability to balance strategic leadership with hands-on execution. As the organization evolves through key clinical and commercial milestones, this role is expected to scale in scope and impact, transitioning from a broad, hands-on HR Business Partner role to a more dedicated commercial HR leadership position.
