Role Overview for Chief Medical Officer (CMO) with a Biopharma Start-up – Cambridge, MA
JRG Partners has been exclusively retained to identify a visionary and experienced Chief Medical Officer (CMO) for our client, a well-funded, clinical-stage biopharmaceutical startup poised to revolutionize the treatment of complex diseases. Located in the heart of the global biotechnology hub in Cambridge, MA, our client is developing a pipeline of first-in-class therapeutics based on a proprietary platform technology. This is a rare opportunity to join a dynamic executive team and shape the future of a company with the potential for transformative patient impact.
The Chief Medical Officer will be the key strategic leader responsible for the entire clinical development lifecycle, from translational medicine and first-in-human studies through to global regulatory submissions and commercial launch. As a core member of the executive leadership team, the CMO will provide critical medical and scientific guidance that will influence corporate strategy, investor relations, and business development activities. You will be instrumental in building a world-class clinical organization, fostering a culture of scientific excellence, and driving the clinical programs forward with urgency and precision. This role requires a hands-on leader who is as comfortable designing a Phase 1 trial as they are presenting to the board of directors or engaging with the FDA. If you are an entrepreneurial physician-scientist with a proven track record of drug development success and a passion for building something truly meaningful from the ground up, we invite you to consider this career-defining role.
