Senior Director, Medical Director

At Viridian Therapeutics, we are focused on developing best-in-class medicines for people living with autoimmune and rare diseases. Leveraging our team’s expertise in antibody discovery and engineering, we have created a robust pipeline of differentiated investigational therapeutic candidates for well-validated targets.

Reporting to the Head of Medical Affairs, the Senior Director, Medical Affairs will partner with key colleagues to develop, lead, and execute medical strategies aligned with the broader organization while providing progress updates to relevant stakeholders. This individual will help ensure our medical strategy is clinically meaningful, scientifically rigorous and shape evidence generation, scientific communications, and external engagement across the lifecycle of our therapies—from early pipeline through launch and post-approval.  

This role may be based in our Waltham, MA headquarters, which would be a hybrid role, or it can also be fully remote. Our office-based employees are required to work in the office three (3) days a week. If remote, travel to headquarters for meetings would be required at the discretion of management.
