Digital Design Intern in London

Responsibilities: You will support with a wide range of digital projects for our clients within the healthcare sector, from initial concept development to full production, allowing for real autonomy and creativity.

Salary: A pro-rated salary of £26,250 per annum outside of London (£28,860 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 and employer pension contributions.

Role Type: Full-time, temporary internship, lasting for either 3 or 6 months.

Start Date: This role will ideally commence in August or September 2026, 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 will close when a suitable candidate is found.

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

About the Role: This internship is ideal for design students or recent graduates who would like to gain insight into an agency or commercial environment, as well as those looking to kickstart a career in design. In this role, you will support with a wide range of digital projects, including the creation of interactive content for conferences and events, the creation of digital marketing materials such as HTML emails, web banners and social media graphics, as well as the design, maintenance, and testing of new and existing websites and web applications. We are therefore looking for talented individuals with a great understanding of aesthetics and meticulous attention to detail. Collaborating with experienced members of our Creative team, you will receive comprehensive training and gain hands-on design experience in the healthcare sector.

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: As a Digital Design Intern in the Creative team, you will have the option to select an internship length of either 3 or 6 months, enabling you to develop your skills and potentially gain experience working on multiple project types. There may also be the opportunity for strong interns to apply for the Digital Designer role and join the team on a permanent basis, depending on business need.
