About the Role

Our Real-World Evidence (RWE) team is growing quickly through demand from both new and existing clients, and we have an exciting opportunity for an Epidemiologist to join our friendly and collaborative team. The successful candidate will play a key role in shaping the future of Costello Medical’s RWE service offering. 

Our RWE team contribute to the design, execution and subsequent reporting of prospective, retrospective or cross-sectional real-world studies. They develop protocols and statistical analysis plans (in collaboration with our Statisticians, clients and external experts), acquire and analyze data, and communicate the methodologies and results in both written and oral formats. Studies include data from patient registries, claims databases, prospective studies or any other source of real-world data, and involve a wide range of research questions on burden of disease, clinical effectiveness or economic topics, among others. 

You will work in project teams alongside colleagues from all specialties to ensure that RWE projects are completed to an exceptionally high standard, on time and in line with client expectations. This role will include a range of work with varying levels of technical requirements. You will receive one-to-one training in the technical aspects of the role, including project management and effective client communication. Delivering project work requires close collaboration with clients, and following a successful induction period you will increasingly participate in teleconferences and face-to-face meetings with external stakeholders. The successful candidate will be someone who shows the potential to progress rapidly and who, with close mentoring, is excited to work towards project management and client responsibilities. 

Our team typically work 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  materials and a broad range of therapeutic areas.

Hybrid Working Policy: We recognize that home-working can improve work life balance, reduce commuting times and costs, and provide the opportunity to juggle personal commitments. At the same time, we believe that having face-to-face time in the office holds many benefits and is central to ensuring that the community we have created, where people have a workplace they belong to and feel part of, is never lost.  

Therefore, we offer flexible working arrangements that allow our colleagues to work from home for up to half of the time, measured across a 2-week rolling period. Please note that as part of our wider flexible working policy, employees may work outside of Massachusetts for up to 4 weeks annually.
