The Opportunity
Praxis is seeking a field-based Senior Medical Science Liaison (Senior MSL) to support Medical Affairs activities for ulixacaltimide during prelaunch and potential launch. This role is focused on building trusted scientific partnerships, delivering high-quality scientific exchange, and generating actionable insights to inform medical strategy and ensure clinical readiness.
