Our company was founded on the premise that protein motion can be leveraged to create breakthrough medicines. The team at Relay is putting this principle into practice, with the aim of accelerating the development of medicines that will make a transformative difference in patients’ lives.

We’re tackling a wide array of compelling target opportunities with an approach that gives us the ability to discover best-in-class drugs in cancer and multiple other areas of high unmet medical need. We’d be nothing without a visionary team that not only pulls it all together, but is willing to stand behind an exciting novel approach.

Our world-class team is equal parts bright and bold, with a shared passion for working in intellectually stimulating environments. We look for people who are committed to working together in a collaborative, rigorous and entrepreneurial culture. We’ve created the kind of work environment that not only gets, but keeps people excited and focused–and we’ve mastered the art of sharing our findings in ways that both educate and inspire. Putting protein motion at the heart of drug discovery will be a challenge, but we are confident that our team’s dedication and urgency will create opportunities that profoundly impact the lives of the patients we serve. 

Headquartered in Cambridge, Mass., Relay Therapeutics is a private company launched with $57M Series A financing from Third Rock Ventures and from an affiliate of D. E. Shaw Research.

Relay invites extraordinarily creative, talented and passionate individuals to join us as we strive to make a difference in patients’ lives. We offer competitive compensation along with a comprehensive benefits package and we recognize the achievements of our employees. Our culture fosters collaboration and excellence. Join our team!
