About RDI

At RDI Trials, we're building a different kind of CRO.

We are an IVD-focused contract research organization. Since 2008 we've run 300+ diagnostic trials for the largest test makers in the world. Our clinical operations team is sharp, motivated, and runs its own workload well — what they need now is someone to raise the ceiling on monitoring craft.

This is not a traditional, process-heavy environment.

We are a small team that moves fast and expects people to take real ownership. There's no passing things along or waiting for direction. If something needs to get done, you step in and figure it out.

The pace is high. The expectations are higher. But for the right person, it's a place where you can learn quickly and have real impact.

Those who thrive at RDI

  •   Take ownership and actually follow things through
  •   Can think for themselves and make decisions without a playbook
  •   Are comfortable when things are not perfectly defined
  •   Understand their work at a deeper level, not just surface
  •   Communicate clearly and directly
  •   Have a strong foundation in their field but are willing to step outside of it

This is a place for people who want to build, not just maintain.

The Culture

We punch above our weight class — a 30-person company running the workload of a CRO twice our size. That happens because of how we work, not how big we are.

We move with speed and discipline. We own outcomes, not tasks. Precision is non-negotiable in our work, so it's non-negotiable internally. Grit matters here — but we'd rather build the systems that scale.

The CEO sets the pace. The COO runs the operation. Leadership is accessible — you'll be in the room. Feedback is fast and unvarnished, and the worst thing you can do is hide a problem.

We just signed the largest contract in company history. The next 18 months will stretch every function, including this one.
