## Job description

## About Ossium

Ossium’s mission is to improve the health, vitality, and longevity of human beings through bioengineering. We develop, manufacture, and bank cell therapy products that apply the power of stem cell science to revolutionize treatment for patients with blood, immune, and orthopedic diseases.  At Ossium, we empower our employees, maintain the highest standards of operational excellence, and are a force for good.

## About the Job

We're hiring a Medical Science Liaison to be the bridge between our cutting-edge cryopreserved deceased donor bone marrow technology and the hematology/oncology and transplant medicine community. As the scientific voice of Ossium, you’ll build relationships with key opinion leaders, translate complex science into compelling clinical narratives, and help physicians and transplant care teams understand how our products transform patient outcomes.

This isn't a traditional pharma MSL role. You'll be working with breakthrough cell therapy technology at an early-stage company, which means real autonomy, meaningful scientific impact, and a direct line to clinical development decisions. This role will be instrumental in building scientific community awareness and supporting our clinical development efforts in the hematology/oncology and transplant medicine space.

We are looking for MSLs in either the South or the Eastern region of the United States.

Required Qualifications

- Advanced degree (PharmD, PhD, MD, DNP, or MS) in life sciences, medicine, or a related field
- 7+ years of experience as an MSL in the U.S.
- Domain experience in stem cell transplant, cell therapy, and/or gene therapy
- Experience engaging academic medical centers or complex hospital systems
- Experience and comfort presenting scientific data to healthcare professionals
- Ability to operate independently in the field and manage a regional territory
- Experience working with academic medical centers or complex hospital systems
- Willingness to travel up to 70% (mostly regional, some national conferences)
- Excellent written and oral communication skills
- High organizational discipline; ability to thrive in a dynamic startup environment
- Candidates must be based in either the South or the Eastern region of the United States

## Preferred Qualifications

- Clinical experience and existing professional relationships in hematology/oncology or transplant medicine
- KOL engagement and advisory board experience
- Track record of successful medical conference presentations

## Key Responsibilities

- Build and maintain relationships with hematology, oncology, and transplant medicine KOLs in your region
- Educate physicians and transplant care teams throughout your region on Ossium’s science and clinical value proposition
- Present clinical data at medical conferences and scientific meetings
- Support clinical trial recruitment and investigator engagement
- Respond to medical information requests from healthcare professionals
- Support advisory boards and scientific advisory meetings
- Collaborate with R&D, Clinical, Commercial, Marketing, and Regulatory on scientific communications
- Monitor the competitive landscape, gather and synthesize market insights
- Contribute to medical publications and conference abstracts

In your first six months, some projects you’ll work on include:

- Identifying key transplant centers in your region, building and nurturing relationships with 15-20 KOLs
- Attending scientific conferences and connecting with key transplant care providers
- Creating and presenting scientific materials for Ossium’s bone marrow products
- Expanding Ossium’s physician education program

We Offer a Full Slate of Employee Benefits Including:

- Competitive salaries
- Stock options
- 401(k) matching
- Medical, dental, and vision coverage
- Four weeks of PTO accrued annually (vacation & sick time) + 11 company holidays
- Employer paid life insurance and long-term disability
