Location:

About the Role:

Our Epidemiologist Internship is ideal for current students and recent graduates with a keen interest in epidemiology, biostatistics and public health, who are 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 analyses of real–world studies or public health data. Specific tasks may include:

• Developing protocols and statistical analysis plans (SAPs)
• Conducting analysis of data from patient registries and electronic health record (EHR) databases
• Supporting primary data generation activities such as prospective cohort studies or patient/clinician surveys

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.

Epidemiologist Interns will work on projects that span our Real‑World Evidence (RWE) and our Literature Reviews teams, giving you broad exposure to our Evidence Development service offering. You will also work in project teams alongside colleagues from all service offerings, as many projects are interdisciplinary in scope. This role will likely be a 3 month internship with a potential to extend to 6 months.

Career Profile:

We offer many opportunities for personal and professional development at Costello Medical. To read firsthand accounts from our colleagues about their time with the company, visit.

Prospects After the Internship:

During the internship programme, individuals performing well may be given the opportunity to extend their internship for up to three 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 Epidemiologist role and join our expanding team on a permanent basis.

Essential requirements for the role are:

• An undergraduate degree level qualification in a relevant discipline (minimum 2.1 or expected 2.1). Postgraduate qualifications (minimum 2.1 or equivalent) would be an advantage, but they are not a requirement for the role.
• Exceptional attention to detail
• Strong analytical skills
• A good understanding of the R programming language used for the analysis of large datasets, and the willingness and ability to rapidly develop your programming skills
• A good understanding of epidemiological techniques and data analysis methods
• Excellent written and spoken English, and the ability to communicate scientific material clearly in both written and oral form for a variety of audiences
• Strong organisational skills and the ability to plan your own work effectively, with a proactive approach to task prioritisation and time management
• The ability to communicate effectively and work collaboratively as part of a team
• Strong self‑motivation, self‑awareness and willingness to learn, with a desire to contribute to the company above and beyond project work
• Fluency in Microsoft Word, Excel and PowerPoint
• A genuine interest in healthcare and an eagerness to learn about new areas of science

What We Offer:

At Costello Medical, we are committed to fair and competitive pay. In line with the Real Living Wage, the salary on offer is:

• £25,800 per annum for colleagues based in office locations outside London
• £27,050 per annum for colleagues based in the London office

These rates reflect regional living costs and our commitment to equitable compensation.

Additionally, you will benefit from:

• Exceptional internal training and mentoring
• Opportunities to contribute to pro bono and charitable projects
• Regular company‑funded social activities
• Flexible working options

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 for 1 day per week.

The Application Process:

You are required to submit your CV and a cover letter via our online application form. In your cover letter, you must explain why you think you would be suited to the role and why you would like to join Costello Medical, with examples to support both. Your CV should clearly state the dates of all qualifications and grades achieved where applicable.

Our recruitment process includes a written assessment and proofreading exercise for you to complete in your own time. If successful, you will be invited to an interview with our Career Development Programme Directors. Our standard recruitment process lasts around 1 month however, this can be adapted if necessary.

As an equal opportunity employer, we are committed to fostering a diverse and inclusive workforce and, throughout the recruitment process, there are a number of reasonable adjustments we can provide.

Please note that this role does not meet the eligibility criteria for visa sponsorship, and you will therefore need the right to work in the UK independently from the company.
