Medical Affairs Lead - Osteoarthritis

NYC, NY; Boston, MA

About Formation Bio

Formation Bio is a tech and AI driven pharma company differentiated by radically more efficient drug development. 

Advancements in AI and drug discovery are creating more candidate drugs than the industry can progress because of the high cost and time of clinical trials. Recognizing that this development bottleneck may ultimately limit the number of new medicines that can reach patients, Formation Bio, founded in 2016 as TrialSpark Inc., has built technology platforms, processes, and capabilities to accelerate all aspects of drug development and clinical trials. Formation Bio partners, acquires, or in-licenses drugs from pharma companies, research organizations, and biotechs to develop programs past clinical proof of concept and beyond, ultimately helping to bring new medicines to patients. The company is backed by investors across pharma and tech, including a16z, Sequoia, Sanofi, Thrive Capital, John Doerr, Spark Capital, SV Angel Growth, and others.

About the Position 

The Medical Affairs Lead is a first-in-function leadership role responsible for building an AI-native Medical Affairs capability across Formation Bio’s growing portfolio. This role will establish the scientific and digital foundation for programs spanning late-stage development to commercialization, with an initial focus on our lead asset, Sprifermin, in osteoarthritis.

This leader will serve as a strategic scientific partner to Clinical Development, Regulatory, Commercial, and Portfolio teams, ensuring that Medical Affairs strategy, scientific exchange, and evidence generation are embedded early and executed with rigor, compliance, and credibility. Critically, this leader will champion the integration of AI-powered tools and data-driven approaches across all Medical Affairs activities—from evidence synthesis and KOL mapping to real-world evidence generation and field team enablement.

The Medical Affairs Lead will design scalable, technology-forward medical affairs infrastructure, lead external scientific engagement, and build a high-impact Medical Affairs team.

Responsibilities

  • Embed medical perspective early in development planning, including endpoint selection, evidence generation, and lifecycle strategy.
  • Provide medical and scientific input into asset diligence, in-licensing evaluations, and portfolio strategy.
  • Champion an AI-native approach to medical affairs—identifying, piloting, and scaling AI tools that enhance scientific rigor, efficiency, and decision-making across the function.

External Scientific Engagement

  • Develop and execute a comprehensive KOL engagement strategy, building durable relationships with external experts, investigators, and scientific leaders in osteoarthritis and related therapeutic areas.
  • Lead scientific exchange activities, including advisory boards, congress strategy, and external data communication.

Publications & Real-World Evidence

  • Own publication planning and execution, ensuring timely, compliant dissemination of clinical and real-world data.
  • Support Phase IV, real-world evidence (RWE), and observational studies in partnership with Clinical and internal stakeholders.
  • Translate evidence into clear medical narratives that inform development, access, and launch readiness.
  • Leverage AI-assisted evidence synthesis, literature monitoring, and data analytics to accelerate insight generation.

Medical Affairs Build-Out

  • Establish scalable medical affairs processes, governance, and operating models appropriate for a multi-asset organization.
  • Build and lead an AI-native Medical Affairs function, identifying and implementing digital tools that improve how the team operates, shares scientific content, and captures field insights.
  • Balance internal capabilities with external vendors and partners to maximize efficiency and impact.

Launch & Cross-Functional Partnership

  • Support launch readiness through medical education strategy, scientific positioning, and internal training.
  • Provide medical affairs input into value narratives, HEOR strategy, and reimbursement dossiers in collaboration with cross-functional teams.

Patient & Advocacy Engagement

  • Develop strategy for engagement with patient advocacy groups and medical societies to inform development, education, and access, including those focused on osteoarthritis and musculoskeletal disease.

About You

  • Experience within osteoarthritis or musculoskeletal disease with deep scientific credibility is required. 
  • Demonstrated experience contributing to or leading medical strategy across late development, pre-launch, or commercialization preferred.
  • Genuine enthusiasm for AI and digital tools applied to drug development and medical affairs; hands-on experience with AI-powered platforms (e.g., for evidence synthesis, KOL analytics, or field enablement) is a strong plus.
  • Experience building or contributing to medical affairs capabilities, including MSL teams, preferred.
  • Deep understanding of medical compliance and scientific exchange regulations.
  • Strong cross-functional partner with ability to work closely with Clinical, Regulatory, Commercial, and Portfolio teams.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities.

To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
