Vendor Manager

At Castor, we’re modernizing the backbone of clinical research Clinical trials are the gatekeepers of human health, yet the industry is still bogged down by fragmented, manual processes that can waste time and exclude patient populations. At Castor, we are building the operating system for the next era of clinical research. We provide a modular cloud platform designed to run trials end-to end. Our foundation is a robust Electronic Data Capture (EDC) system, supported by eConsent for recruitment and screening and eCOA to accurately capture patient reported outcomes. We don’t just stop at data collection; we use Castor Catalyst (our high-precision AI automation) to strip away the manual effort that historically makes research slow and expensive. How we work: Trust over tracking We are a remote first company built on the belief that talented people do their best work when they have the agency to manage their own lives. We believe that high performance requires a foundation of trust, health, and cutting-edge support. Work life integration: We don't believe in performative presence. We trust you to own your schedule and show up for your team, while also making space for your life outside of work. Deep work & async: We protect your time.
