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.

Your mission and impact

As a Senior Project Manager you will lead our most complex, multi-component, multi-country studies, serving as a subject matter expert. Your value to the projects lies in your critical thinking and ability to translate high-level, often vague project scope into robust and operationally sound project plans & deliverables.

This is not traditional task-tracking, but high-autonomy and consultative on specialised or new services. You will navigate the increased variables and technical and operational dependencies that come with complex studies, operating with minimal oversight. Please note that this is a strategic position focused on project delivery and does not include direct people management. You will act as the pivotal bridge and consultant to the customer, taking ownership of the end-to-end delivery from ensuring internal project cohesion to leveraging your risk expertise to confidently articulate challenges and guide external stakeholders to the best possible solution.

Who are you

What you’ll bring

Accepting candidates +2/-2 CET. At this time, we cannot accept applications from France, Germany, Spain, or Switzerland.

How we invest in you

High performance isn't sustainable without real support. We provide the infrastructure you need to stay healthy, focused, and rewarded.

Compensation at Castor

Castor is a remote, globally distributed company, and as such we use location based salary bands. We believe compensation should be fair and transparent, without unnecessary complexity. For us, compensation means salary + equity + benefits, all of which are designed to support you in doing your best work, wherever you are.

This position is open to candidates across multiple regions. Before your interview is scheduled we will share the corresponding regional band for your specific country.

Belonging at Castor

We build products to make research accessible to everyone, and we believe our team should reflect that same diversity.

Our remote setup is designed to support you as a whole person—your family, your mental health, and your authentic self.

We don't care about your background as much as we care about your perspective and your expertise. We strongly encourage applications from women, people of color, and the LGBTQ+ community. Please feel free to share the pronouns you use (for example she/her/hers, he/her/his, they/them/theirs, etc.).
