Job description

Overview

Researched and relatable, science-driven and social, you're an extroverted expert who thrives in fast-paced clinical environments. Your advanced training has prepared you to rapidly expand your expertise and stay at the forefront of scientific innovation. You build strong relationships with ease, engage comfortably with thought leaders, and excel at collaborating with investigators and study sites. Poised, articulate, and scientifically grounded, you excel as a listener, educator, and a connector of new opportunities. In this Medical Affairs role, you will serve as a scientific expert responsible for nonpromotional scientific exchange, insight gathering, and strategic engagement with key opinion leaders and healthcare professionals. Simultaneously, you will partner with clinical research stakeholders to support the successful execution of clinical trials through site engagement, patient recruitment support, and enrollment optimization. These qualities position you for success as a Medical Science Liaison with Syneos Health.

Responsibilities

The Medical Science Liaison is a field-based, scientific, and clinical expert who strategically supports both the medical objectives of the program and the successful execution of clinical trials. Key aspects of this role include engaging in peer-to-peer scientific dialogue with healthcare professionals and serving as a key field resource for study sites.

  • Establish, cultivate, and maintain strategic scientific relationships with KOLs, principal investigators, study coordinators, and other healthcare professionals while developing a strong understanding of clinical practice and evolving therapeutic landscapes.
  • Partner with Clinical Development, Clinical Operations, CRO partners, and investigative sites to support effective study startup, protocol understanding, and trial execution.
  • Execute nonpromotional scientific exchange and communicate clinical and scientific data through presentations, educational programs, and scientific discussions.
  • Collaborate with investigative sites to develop and implement patient identification, recruitment, and retention strategies to support enrollment goals, including taking responsibility for building out referral networks.
  • Monitor site engagement and enrollment activity, proactively identifying and helping resolve operational barriers impacting study execution or patient recruitment, and facilitating communication for timely issue escalation.
  • Gather, analyze, and communicate actionable medical insights, as well as field-based insights related to recruitment challenges, site engagement trends, and operational needs to support cross-functional internal teams.
  • Serve as a therapeutic and scientific resource for healthcare professionals by addressing unsolicited medical questions and facilitating meaningful scientific dialogue.
  • Maintain deep scientific and clinical expertise through continuous learning, scientific literature review, and awareness of emerging data and treatment trends.
  • Support congress activities, advisory boards, and other medical education initiatives as appropriate.
Requirements
  • Advanced degree preferred (e.g., PharmD, PhD, MD, DNP, PA, or equivalent)
  • Prior Medical Science Liaison experience
  • 2+ years' experience supporting clinical trial operations, patient recruitment, or investigative site engagement required
  • Knowledge of clinical trial/research design, conduct, and understanding of clinical study results
  • Deep scientific knowledge and genuine passion for Neurology & Rare Disease
  • Experience in Epilepsy & Pediatrics is a strong plus
  • Experience engaging healthcare professionals in scientific exchange
  • Ability to interpret and communicate complex clinical and scientific data
  • Strong presentation, oral, and written communication skills with the ability to effectively engage a variety of clinical research stakeholders
  • Willingness to travel
  • Valid driver's license and ability to travel by car and air

The annual base salary for this position ranges from $190,000-$210,000. The base salary range represents the anticipated low and high of the Syneos Health range for this position. Actual salary will vary based on various factors such as the candidate's qualifications, skills, competencies, and proficiency for the role. Some positions may include a company car or car allowance and eligibility to earn commissions/bonus based on company and/or individual performance.

The benefits for this position will include a competitive compensation package and health benefits to include medical, dental and vision. Company match 401(k), flexible paid time off (PTO) and sick time. Because certain states and municipalities have regulated paid sick time requirements, eligibility for paid sick time may vary depending on where you work.

Syneos Health companies are affirmative action/equal opportunity employers (Minorities/Females/Veterans/Disabled).
