Job Description
Position: Medical Science Liaison, Oncology (Gyn-Onc)
Location: California
Medical Science Liaison, Oncology (Gyn-Onc) Company
Our client is a well-established, publicly traded biopharmaceutical company that has spent more than two decades singularly focused on the science of a single hormonal signaling pathway, building a portfolio of more than 1,000 proprietary compounds along the way.
The company's newest FDA-approved therapy - its first entry into oncology - targets a defined hormone-receptor mechanism in a hard-to-treat gynecologic cancer, backed by practice-changing Phase 3 trial results published in a leading medical journal.
Candidates consistently point to the company's collaborative, data-driven culture and its rapid, well-funded growth as reasons to join.
The Role They Will Play
As a Medical Science Liaison, you will serve as the scientific bridge between the company and oncology thought leaders across a defined U.S. field territory.
You’ll lead in-depth scientific exchange with HCPs treating gynecological and other malignancies, respond to medical inquiries, and support the field medical strategy behind a newly launched, first-in-class oncology therapy.
This is a ground-floor opportunity on a brand-new oncology franchise inside an already-profitable, publicly traded company - a combination of launch-stage energy and commercial stability that’s uncommon in MSL roles.
As the therapeutic area expands into additional tumor types, strong performers have a clear runway toward senior MSL and field leadership roles.
Territories
• North Central - covering Wisconsin, Minnesota, Nebraska, Iowa, North Dakota, and South Dakota
• South Central - covering Southern and Central Texas
• Southeast - covering Tennessee, Alabama, Georgia, and South Carolina
• Southern California - covering Los Angeles, San Diego, and Hawaii
The ideal candidate will bring:
• Expertise in oncology, ideally gynecologic oncology.
• 1-3+ years' MSL experience; 2+ years' experience in oncology.
• Exposure to thought leader engagement and scientific exchange within a regulated pharmaceutical environment.
• Working knowledge of CRM/vault platforms (e.g., Veeva) commonly used in field medical roles.
• Advanced degree (PhD, MD, PharmD, MSN, PA, or NP) or equivalent experience required.
