The Company

We are Alloy Therapeutics — a biotechnology ecosystem and Product Development Organization (PDO) empowering the global scientific community to make better medicines together. Through a community of partners, we democratize access to pre-competitive tools, technologies, services, and company creation capabilities that are foundational for discovering and developing therapeutic biologics. The company facilitates affordable, non-exclusive access to the entire drug discovery community from academic scientists, small and medium biotech, to the largest biopharma.

At Alloy, we believe our industry should compete on getting the best drugs to patients as quickly as possible, not exclusive access to the best platforms. As a reflection of our relentless commitment to the scientific community, we reinvest 100% of our revenue in innovation and access to innovation. May the Best Drug Win.

Alloy has evolved from a startup into a global product development organization operating 11 divisions across 5 research sites in 4 countries on 3 continents. Our model - Integrated Independence - combines centralized capabilities with entrepreneurial operating divisions. Successful members thrive in our shared culture of accountability, deliberate trust, and open communication.

As a team we aspire to work together to exceed expectations and collectively contribute across the global organization to always maintain our nimble, startup culture.

At Alloy, we have an ethos of "Mentorship-By-Apprenticeship" in all of our positions. We strive to have workers in the office when needed to interact organically and face-to-face. Of course, as a lab-based operation, our cells and animals grow 7 days a week, 365 days per year.

We respect and value our colleagues for their hard work that requires them to be in the lab every day. We ask our people who have more flexible accommodations to appreciate their colleagues who have less flexibility. We are all one team!

About the Role at Alloy Therapeutics

As Director of Protein Science, you will lead a team responsible for high-throughput mammalian protein production and mg-scale expression in support of therapeutic programs.
