Senior Scientist - Target Validation 

Peak Bio


Peak Bio is a newly created venture out of the San Francisco Bay Area that will soon reach a critical milestone in our history of going public on NASDAQ. We are seeking scientific and business talent at two of our critical sites that include our center of research excellence in Palo Alto, California and our G&A infrastructure in South Florida.

Peak Bio is a clinical-stage biopharmaceutical company focused on commercializing innovative therapeutics that aim to improve and address significant unmet medical needs for patients with inflammatory, rare and specialty diseases and cancer. We seek qualified, energetic, and talented individuals with a desire for growth, and advancement but with a knack for working in a cross-cultural, team-based environment. The talent we seek works well with others and knows that, in the end, the company’s overarching goal is to improve the human health experience and help solve the medical mysteries that challenge us daily. As a company we will continue to explore, work closely with and partner with external researchers, clinicians, patient advocacy groups, academic institutions, governmental agencies, and our investors to continue to expand treatment options and partnerships to meet those expectations and find novel approaches to treat disease.

This is a full-time position based in our Palo Alto, California offices, and reports directly to the Head of Oncology.
