We work dynamically. We combine the ability to be onsite as roles require with the flexibility to work remotely. Our onsite facilities are designed to inspire our employees’ best work with open work and collaboration spaces, state of the art labs and best in class technologies. Located in the life sciences hubs of South San Francisco, Seattle, and Bothell these locations offer modern amenities, cafeterias, mother’s rooms, and free parking. We also provide weekly lunches for employees to come together and build a sense of community. Some locations offer onsite gyms, showers and fitness classes.


We want to attract the best talent. We are committed to hiring people with diverse backgrounds and experiences because we recognize that their individual approaches and perspectives are key to delivering cell therapies for patients with solid tumors. As we seek out exceptional talent to help us reach our goal, we strive to deliver a great experience for every candidate from the initial contact through to their start date.
