Scientist, Targeted Proteomics ekuhn  2021-04-23

We are seeking an experienced Scientist in Targeted Proteomics to join our team at Kymera Therapeutics. The successful candidate will develop assays, characterize their performance and implement them by analyzing samples from a wide range of tissue types and species to assess PD/PK performance of Targeted Protein Degradation drugs and verify biomarker discovery candidates. This candidate will be expected to expeditiously generate high quality data, effectively communicate the results to the project teams and collaborate with individuals experienced in each function of drug discovery pipeline and disease area throughout the company.

Kymera Therapeutics is a clinical stage biotechnology company focused on advancing the field of targeted protein degradation (TPD), a transformative new approach to address previously intractable disease targets. Kymera’s Pegasus™ TPD platform harnesses the body’s natural protein recycling machinery to degrade disease-causing proteins, with a focus on undrugged nodes in validated pathways currently inaccessible with conventional therapeutics. Our mission is to discover, develop, and commercialize transformative therapies while leading the evolution of targeted protein degradation. Kymera’s goal is to become a fully integrated biopharmaceutical company with a pipeline of novel medicines, with an initial focus on immune-inflammatory diseases and oncology.

In 2021, we plan to continue to grow and strengthen our organizational capabilities to deliver on the potential of inventing a new class of protein degrader medicines for patients. Kymera is rapidly advancing three programs in clinical studies this year. We are also actively advancing a broad pipeline of preclinical programs across a wide variety of diseases, both internally and in collaboration with our partners Sanofi and Vertex Pharmaceuticals.
