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.

Start Date: We are currently recruiting for start dates in January, February and March 2026, and you will be asked to state your availability on your application form. This internship will last for 6 months.

Location: This role is available in our London, Manchester and Bristol offices.

Our Health Economics Internship is ideal for current students and recent graduates in an economic, mathematical or computer science discipline seeking to gain an insight into life at a fast-growing consultancy serving clients from the pharmaceutical industry. Projects can involve developing simple costing tools to substantially more complicated models that aim to demonstrate the value of products and therapies to reimbursement agencies. Health Economists at Costello Medical create economic models to guide resource allocation for healthcare providers and share insights with industry stakeholders through cost-effectiveness analyses or separate cost and benefit evaluations. These models are typically built in Microsoft Excel (and occasionally R, or C++), employing universal mathematical and statistical modelling techniques. Model development can involve fitting statistical distributions and parametric survival curves to clinical data and therefore requires a good knowledge of statistics. The models developed by our Health Economists have real-world implications, aiming to improve the efficiency of healthcare systems by using robust methodological frameworks to inform decision-making that brings treatments to people who need them.

Key responsibilities will include:

• Conduct research and critically appraise medical and economic literature to inform project objectives.
• Understand and apply theoretical health economic frameworks to relevant projects.
• Develop high-quality, technically robust, and clinically valid models using Microsoft Excel or other relevant software.
• Interpret and analyse model results, producing accurate and comprehensive reports detailing methodologies and outcomes.

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.

Career Prospects After the Internship: There is an opportunity for strong candidates to apply for the Health Economist role and join our expanding team on a permanent basis, dependent on business needs.

This internship is open to undergraduates and post-graduates, professionals considering a career change, as well as current students who can complete full-time internships outside of term time or as part of their degree. Please note that we do not recommend completing the Health Economist Internship programme at the same time as studying, completing a dissertation or writing a PhD thesis due to the competing demands of your course and the role.

Essential requirements for the role are:

• An undergraduate degree level qualification in an economic, mathematical or computer science discipline (minimum 2.1 or equivalent).
• Postgraduate qualifications (minimum 2.1 or equivalent) would be an advantage, but they are not a requirement for the role.
• An A-level in Mathematics (minimum B grade or equivalent).
• An excellent level of attention to detail in both quantitative and qualitative settings.
• Strong organisational skills, the ability to plan your own work effectively and the flexibility to respond to changing deadlines.
• The ability to communicate mathematical and economic material clearly in both written and oral formats.
• A problem-solving mindset and eagerness to work both independently and collaboratively to find solutions.
• Integrity, a proactive approach to your work, and a keen interest in developing your skills.

At Costello Medical, we warmly welcome applicants from academia who are looking to transition into a role within a commercial, industry-based setting. We understand the unique perspectives and valuable skills that academic professionals bring to our team. To support your career change, we offer comprehensive training, mentorship programs, and a work culture that fosters collaboration, growth and innovation.

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.

Interns also benefit from:

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

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 video interview which can be conducted at your own convenience. If successful, you will be sent a technical and proofreading assessment which requires you to use Excel and can be completed in your own time. Following successful assessments, you will then be invited to an interview.

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.
