Boundless Bio is discovering and developing novel cancer therapeutics based on the role of extrachromosomal DNA (ecDNA) in driving tumorigenesis, resistance and recurrence. When DNA in cancer cells comes off chromosomes, “extrachromosomal DNA (ecDNA),” it becomes unbound and unwound, thereby enabling numerous copies of cancer-causing genes, driving cancer cells to grow and allowing them to resist treatment. At Boundless Bio, we are counterattacking this ecDNA phenomenon with boundless innovation and boundless energy to develop powerful new cancer medicines that eliminate cancer cells’ ability to employ ecDNA to survive. Our Culture: At Boundless, you’ll experience what it means to be out in front of the wave. Our unprecedented science takes us to new shores, and our team navigates the best breaks. We’re leaders in our field, and we’re dedicated to the cause of understanding and treating intractable cancers. Every employee at Boundless makes an unbridled impact on our capabilities and our culture. We’ll help you expand your abilities and defy your bounds by providing meaningful work and unbounded opportunities. Career development is essential at Boundless. We’re all in on thi
