As a Statistician at Astellas, you are responsible for the statistical integrity of clinical trials. This involves writing and reviewing statistical analysis plans (SAPs), performing complex data analyses, and interpreting results to support clinical development programs. You will often serve as the primary statistical lead for specific projects, ensuring that all outputs meet regulatory requirements and internal quality standards.

Collaboration is essential. You will work closely with data management teams to ensure data quality, and with clinical leads to ensure that statistical outputs address the core research questions. You may also provide input into trial design, helping to shape the study parameters to maximize the probability of success. Your daily work involves a combination of deep technical coding, cross-functional meetings, and documentation of statistical processes.

To be a competitive candidate for the Statistician position at Astellas, you should possess a strong foundation in both statistical theory and practical clinical application.

• Must-have skills – Advanced degree in Statistics or Biostatistics; significant experience in clinical trial environments; proficiency in R or SAS.

Q: How long does the interview process typically take? The timeline can vary, but generally, it involves several stages spanning a few weeks. Be prepared for a mix of remote calls and potential panel presentations.

Q: What differentiates a successful candidate? Successful candidates are those who can clearly articulate their technical choices and demonstrate a genuine interest in the clinical outcomes of their work. Being able to explain the "why" behind your "how" is critical.
