About the Role

Our Statistics team provides statistical and analytical expertise across Costello Medical, devising statistical analysis plans and performing data analysis within R, Excel, Stan, SQL and BUGS software. They are also responsible for communicating the methodologies and results in both written and oral formats to drug and device manufacturers, and doctors. The statistical analyses vary across patient‑level clinical trial data, observational study (real‑world) data, and published aggregate data. Our work involves a range of techniques such as basic statistical analysis of individual patient data, regression analysis, survival analysis and complex Bayesian network meta‑analysis using both standard and emerging methods.

The Senior Statistician will lead statistics projects, working very closely with the Consultant or Team Lead as well as colleagues from all specialties, to ensure that statistics projects are delivered to an exceptionally high standard, on time and in line with client expectations. This involves providing strategic advice to clients at project initiation, supervising the project team and regular interaction with external stakeholders by teleconference, email and in person. The Senior Statistician will also be central to the quality control of the project, involving the review of colleagues’ work and the provision of constructive feedback.

Our team typically works on several projects at one time and the results of each analysis can feed into publications, value materials, health economic models or health technology assessment submissions. You will therefore be exposed to a wide variety of our service and a broad range of therapeutic areas. You can read more about our recent articles and publications on our website: https://www.costellomedical.com/research/articles-publications/.

You will also play a key role in contributing to business development by developing and maintaining excellent client relationships and identifying opportunities to provide additional services to clients within projects. There may also be opportunities to line‑manage and mentor our Statistician Interns.
