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. We prioritize thoughtful, asynchronous communication so you can focus on solving hard problems without a calendar full of status update meetings.
• Radical candor: We value the truth over hierarchy. We give and receive direct feedback because that’s how we grow, as individuals and as a company.

Your mission and impact

As our Vendor Manager, you will ensure our external vendors act as a seamless, high quality extension of Castor's solutions. Your mission is to build and maintain a reliable vendor ecosystem that supports our Sales, Professional Services and Data Management teams. You’ll optimize vendor performance, ensure timely procurement of study-critical services, and maximize the impact of our clinical research deliveries!

Who are you

• You are passionate about optimizing external networks, turning vendors into high-performing extensions of our team, and maximizing profit margins.
• You inherently value compliance, taking accountability for the availability, integrity, and confidentiality of vital ecosystem data.
• You master the art of remote work, leveraging deep work and thoughtful coordination to align cross-functional internal teams with external stakeholders.

What you’ll be doing

• Support the identification, selection, onboarding, and day-to-day management of clinical study vendors across supporting service lines (e.g., CTMS, eTMF, eCOA scale licensing, translations, patient recruitment, etc.).
• Collaborate with Sales, Marketing, and Solutions to equip the commercial team with the knowledge and collateral needed to effectively position complementary vendor services alongside Castor’s core offerings.
• Act as the primary operational point of contact for external partners, managing escalations, performance reviews, and ensuring strict adherence to Castor's Quality and Information Security Management System (QISMS)

What you'll bring

• 3+ years of experience in vendor management, account management, or business development within the SaaS, Life Sciences, or eClinical industry.
• Practical experience with contract negotiations, profit margin tracking, process improvements, and managing complex vendor matrices.
• Cross-functional adaptability across software and services, with a genuine interest in practical AI solutions that eliminate manual burdens in clinical trials.

It would be good if you had:

• A strong understanding of the clinical research space (Sponsors, CROs, eClinical tech) and familiarity with core systems like EDC, eCOA, or eConsent.

Our preference is for this role to be based in CET +/-2. Unfortunately at this moment we cannot accept applications from France, Spain, Belgium, Germany and 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.

• Rest is non-negotiable: Unlimited annual leave with 25 day minimum. We don’t just allow time off; we expect you to take it.
• Downtime weeks: Once a quarter, the whole company shifts gears. No new shipping, just a week for deep focus, learning, or catching up so we can start the next quarter fresh.
• AI-first culture: We provide the tools and training to ensure you’re spending your energy on high-value work, not manual repetition.
• Real ownership: All Castor team members are offered options through our Employee Stock Option Plan (ESOP).
• Comprehensive wellbeing: Free access to Open Up for mental health, specialized sleep courses (for you and your family), and a budget to make your home office a place you actually want to be.
• Annual bonus: A guaranteed "Happy Holidays" bonus every December.

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.
