Scientific Data Careers at Parexel
Using Real-World Data to optimize study designs for the patient journey
Parexel’s Scientific Data Organization (SDO) plays a critical role in shaping the future of data‑enabled clinical development. Our teams are redefining how real‑world data and advanced analytics inform clinical trial design, operational strategy, and patient engagement across the entire product lifecycle.
Our global SDO brings together multidisciplinary experts in medical informatics, data science, biostatistics, epidemiology, and big‑data engineering. Together, we’ve built a comprehensive real‑world data (RWD) ecosystem that connects patient information across the healthcare landscape — creating a more complete, continuous view of each patient’s journey. This ecosystem powers a wide range of strategic applications, from RWD‑enhanced clinical trial designs to advanced patient‑sensor and digital‑health solutions.
As part of the SDO, you’ll help uncover meaningful insights into patient behavior, geographic disease patterns, treatment and prescribing trends, and study feasibility. Your work will directly influence smarter, faster, and more patient‑centered clinical research — enabling sponsors to make better decisions and bring life‑changing therapies to patients sooner.
Be part of the team redefining what’s possible in clinical research — powered by data, driven With Heart®.
