Senior People Operations Specialist (Temporary)

Who is Castor?

Our People team supports all the awesome ‘Castorians’ who make the magic happen. We’re on the lookout for a passionate Senior People Operations Specialist to join the team.

Castor is a leading cloud-based clinical data platform working with some of the world’s largest pharmaceutical companies, medical device companies, biopharma, and renowned academic institutes.

We simplify the clinical trial process, from recruitment to analysis, with user-friendly, patient-centric technology. Our mission is to bring medical research into the digital age. Why? Because medical research is still largely run using free-text, paper, and legacy technology.

Our self-service platform enables our users to run remote (decentralized), device-enabled, patient-centric trials. By helping our users capture high-quality data and making it machine-readable, we are fundamentally changing the flawed evidence-based medicine process.

How is Castor supporting the Coronavirus crisis?

Castor has joined the global fight against the Coronavirus by making our research data capture system available for free for all COVID-19 research projects. As a result, Castor is supporting more than 200 COVID-19 studies across the world, including the World Health Organization’s SOLIDARITY trial.
