Costello Medical are growing quickly through demand from both new and existing clients and are therefore looking for candidates with prior experience in medical affairs and/or publications who enjoy content delivery, as well as project and client management, to join us as Senior Medical Writers in our Medical Communications team. In this role, you will be at the forefront of our exciting expansion in the US market.

This is a unique opportunity to influence and drive change in our fast-growing company, in a role you can shape to be your own, where we can offer excellent career development opportunities to high performing individuals.

Senior Medical Writers take a leading role across projects, providing strategic advice to clients, supervising the project team, and producing high-quality scientific content themselves. They ensure projects are delivered to an exceptionally high standard and in line with agreed timelines. This role involves regular client communication, project planning, reviewing colleagues’ work, providing constructive feedback, scientific writing and contributing to business development by identifying new clients, writing proposals, and building and maintaining excellent client relationships.

You will be based in our office in Boston, which was established in 2020. This presents opportunities to shape and drive our US company, whilst being supported by the success of our existing operations in the UK and Asia. You will work closely with our Boston-based Team Heads, who each have 7–10+ years of experience in the industry, as well as other senior colleagues in the US and globally.

Hybrid Working Policy: 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. At the same time, we recognise that homeworking can improve work life balance, reduce commuting times and costs, and provide the opportunity to juggle personal commitments.

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.

At Costello Medical we think that the road to success is through investing in and developing our talent. Because of that philosophy, we believe that our environment is the perfect place to grow your career, and here are a few reasons why:

• We are invested in our culture: We make it a priority to create an energetic, fun and supportive work environment while still delivering the highest standard of work to our clients. As a result, we achieved our B Corp certification in 2022
• Join us early in our US venture: Our US operations are relatively new and growing…
