Senior Medical Science Liaison - Movement Disorders

Location:  This position may be performed remotely, but requires the flexibility and willingness to travel as needed.

The Opportunity

Praxis is seeking an Senior Medical Science Liaison (Sr. MSL) to lead and develop a team of Medical Science Liaisons (MSLs) supporting pre-launch and launch activities for ulixacaltimide in movement disorders. This is a hands-on leadership role responsible for building, coaching, and directing a high-performing field medical team, while also maintaining strategic engagement with key investigators, movement disorder specialists, and other neurology stakeholders.

This individual will play a critical role in translating medical strategy into field execution, ensuring high-quality scientific exchange, and driving clinical and account readiness in advance of and following potential approval. The role requires a balance of people leadership, strategic thinking, and field engagement, operating as both a coach and scientific leader within a dynamic, fast-paced launch environment.

Given the significant unmet need in essential tremor and the opportunity to introduce a novel therapeutic option, this role will help shape disease education, stakeholder engagement, and the evolving treatment paradigm across both academic and community neurology settings.

The Associate Director/Director will partner cross-functionally with Medical, Clinical Development, Commercial, and Market Access teams to align on strategy, shape field insights, and ensure consistent, compliant execution across the MSL organization.

This role will also be responsible for translating field insights into actionable strategic recommendations, representing the voice of the external medical community, and shaping field medical strategy across the product lifecycle from pre-launch through post-launch adoption.

The role includes responsibility for field team effectiveness, including performance management, territory alignment, and resource deployment to ensure optimal execution and impact.

This role will report directly to the Head of Field Medical Affairs and serve as a key leader within the field medical organization.

Success in this role requires strong clinical credibility, excellent communication skills, strategic thinking, and comfort operating autonomously in a fast-paced environment.
