Analyst/Medical Writer Internship 2026

Responsibilities:

• You will have the opportunity to gain hands-on experience with a variety of projects, typically working on two to three at any one time, and likely across two different teams, for the duration of your internship.

Salary:

• A pro-rated salary of £25,800 per annum outside of London (£27,050 per annum in London).

Benefits:

• Statutory holiday allowance.
• Flexible working hours and the chance to work from home 1 day per week.
• Numerous internal training and mentoring opportunities.
• Employer pension contributions.

Role Type:

• Full-time, temporary internship.

Start Date:

• We are currently recruiting for start dates throughout 2026, including January, April, July and September, and you will be asked to state your availability on your application form.

Application Deadlines:

• Whilst there are no set application deadlines, we strongly recommend applying as early as possible. The role, or particular start dates, may close when suitable candidates are found.

Location:

• This role is available in our Global Headquarters in Cambridge, as well as our London and Manchester offices.

About the Role:

Our Analyst/Medical Writer Internship is ideal for current students and recent graduates in scientific disciplines, eager to gain valuable insights into life at a leading healthcare consultancy. You will gain practical experience by contributing to two or three projects during the internship, each of which involve the interpretation, assimilation, and creative presentation of clinical or health economic data. Depending on your team and project allocations, you may work on anything from medical communications to market access and evidence synthesis.

Specific tasks may include:

• The preparation of medical education slides.
• Performing systematic searches of medical literature.
• Developing clinical trial manuscripts.
• Assimilating clinical and cost-effectiveness evidence to support HTA submissions to NICE.

These meaningful and exciting projects contribute to improving healthcare outcomes globally. Interns will receive one-to-one training on the technical aspects of the role and learn about project management and effective communication with clients. Your designation as either an Analyst Intern or Medical Writer Intern will depend on your team allocation; however, the core responsibilities of both roles remain the same.

Our teams are generally organised under the service areas of Medical Communications, Value and Access, and Evidence Development, and also encompass specialist areas such as Rare Diseases, MedTech, and Health Policy. If you have a particular interest in any of these service areas, include this in your cover letter. Please note that your team allocation will be confirmed closer to your start date. Whilst we will do our best to accommodate your preferences, final team allocations will be determined by business needs.

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. Given the wealth of training, mentorship and development opportunities that are available as part of our internship programmes, time spent in the office is even more crucial. Therefore, our Interns can work from home 1 day per week.

Career Prospects After the Internship:

During the internship programme, individuals performing well may be given the opportunity to extend their internship for up to 3 months (note that this is dependent on business need and is only applicable to those on a 3-month internship). When this happens, it allows our interns to further develop their skills and potentially gain experience of other areas of the company (again, dependent on business needed as well as the individual’s interests). Additionally, there is the opportunity for high-performing interns to apply for the Analyst/Medical Writer role and join our expanding team on a permanent basis.
