Biomarker Scientist

Join us as we transform immunology and deliver medicines that help autoimmune patients get their lives back. argenx is preparing for multi-dimensional expansion to reach more patients through a rich pipeline of differentiated assets, led by VYVGART, our first-in-class neonatal Fc receptor blocker approved for the treatment of gMG, and with the potential to treat patients across dozens of severe autoimmune diseases.

We are building a new kind of biotech company, one that maintains its roots as a science-based start-up and pushes our commitment to innovate across all corners of our business. We strive to inspire and grow our company, our partnerships, our science, and our people, because when we do, we deliver more for patients. 

argenx is a fast-growing, clinical-stage biopharmaceutical company focused on developing innovative antibody-based therapies to improve the lives of people with severe autoimmune diseases. Leveraging our unique antibody engineering technologies and the complementary expertise of our global team, we have built a differentiated pipeline of novel product candidates, tailored from discovery through development to meet specific patient needs. As we expand our therapeutic franchises across neuromuscular, neurology, rheumatology, and nephrology indications, we remain deeply committed to our core values of collaboration, empowerment, humility, innovation, and excellence—always staying science-based, data-driven, and patient-focused.
