From its sites in Watertown, Massachusetts and Zurich, Switzerland, Repertoire is advancing a pipeline of T cell-targeted immunotherapies with the potential to address a broad range of cancers and autoimmune disorders. The company's lead oncology program, RPTR-1-201, a TCR bispecific, has initiated a Phase 1/2 clinical trial across multiple solid tumor indications. Repertoire plans to advance additional TCR bispecific therapies into clinical trials over the next 12-18 months. In autoimmune disease, Repertoire is partnering with leading pharmaceutical companies to develop mRNA tolerizing therapies designed to selectively expand regulatory T cells and reset the immune system.
Repertoire was founded in 2019 by Flagship Pioneering and is supported by a strong investor base. The DECODE platform has been validated through four strategic partnerships with leading pharmaceutical companies — Bristol Myers Squibb, Genentech, Eli Lilly, and Pfizer — representing over $4.5 billion in disclosed total deal value and $185 million in upfront payments received to date.Role OverviewThe Associate Director, Human Resources is the second member of the HR function and partners directly with the VP of Human Resources to build, operate, and scale the people infrastructure of a growing, two-country biotech. This on-site role holds end-to-end accountability for HR operations, benefits and total rewards administration, employment compliance, talent acquisition, and day-to-day business partnership with functional leaders and their teams.
This is a broad, hands-on role. The Associate Director executes transactional work — Form I-9 completion, interview scheduling, benefits reconciliation, HRIS data entry — while designing the processes, policies, and systems that will allow the function to scale.

What We Do
Repertoire Immune Medicines is a biotechnology company dedicated to creating treatments for diseases based on the power of the human T cell repertoire to eliminate cancer cells, target pathogens, and regulate immune function in autoimmune disease. The company’s proprietary DECODE™ platform provides a comprehensive understanding of the interactions between T cell receptors and their antigens in disease. DECODE uniquely elucidates the entire immune synapse, including the T-cell receptor-epitope pairs that defines it, the HLA context, and the T cell phenotype. This capability enables the creation of new and potentially transformative classes of immune-based medicines. Repertoire believes the ability to decipher these interactions represents one of the greatest opportunities for innovation in medical science. The company is utilizing the discoveries from DECODE to design and develop novel immune therapies for multiple therapeutic areas, such as autoimmune diseases, infectious diseases, and cancer. The team operates from sites in Cambridge, Massachusetts and Zurich. To learn more about Repertoire, please visit www.repertoire.com.
