About The Company
Vividion Therapeutics, Inc. is a biotechnology company focused on transforming the future of human health through the creation of highly selective small molecule medicines that drug traditionally inaccessible targets. The company is advancing a broad, diversified pipeline of multiple, selective small molecule therapeutics for highly sought-after disease-causing target proteins in oncology and immunology. The company’s cutting-edge platform was spun out of the labs of Vividion’s scientific founders, a team of experts in chemical biology and synthetic chemistry from The Scripps Research Institute in La Jolla, CA.
About the Role

Description

Company Overview:


Vividion is a next generation biotechnology company based in San Diego that is leveraging its proprietary chemical proteomics platform to conduct proteome-wide footprinting of drug-protein interactions with unprecedented breadth and precision. Our technology allows us to screen, identify and optimize novel drugs that selectively bind virtually any protein, including proteins previously considered “undruggable”. Our pipeline and emerging programs reflect a matured and productive platform capable of delivering first in class drugs utilizing novel mechanisms of action (allosteric inhibitors, protein-protein interaction inhibitors, functional activators, degraders etc.) against undruggable targets in the oncology and immunology space.


We prize scientific excellence, creativity, team players and we are committed to continued innovation. We have worked hard to create a collaborative and dynamic work culture where your ideas and discoveries are valued and will have an impact. We are growing and there are opportunities for mentorship and career progression.


Vividion has been recognized as a Top Workplace by The San Diego Union-Tribune from 2022 to 2025.
