We are seeking a proactive individual eager to embrace new challenges with a friendly, positive, and ‘can-do’ attitude. You will also value the opportunity to develop your skills and knowledge through formal training, while building professional experience in a dynamic and fast-paced office environment.

This role requires strong organisational skills and a commitment to balancing professional and academic responsibilities. Therefore, managing your own time effectively and maintaining focus will be essential for success in this apprenticeship.

Essential requirements for the role are:

• Grade 6 or higher in GCSE Maths and English. A-levels would also be an advantage

• Exceptional attention to detail
• The ability to prioritise your work and study time effectively, adapting to changing deadlines as needed

• A salary of £22,500 per annum, as well as a discretionary profit share bonus paid twice per year

• Flexible benefits scheme offering cash payments, additional pension contributions and more

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 who have passed probation to work from home up to half their time, measured across a 2-week rolling period. During your probationary period (normally the first 6 months of the role), you will be able to work from home 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.

Our recruitment process then begins with a telephone interview conducted by a member of the Talent Acquisition team. If successful, you will be invited to an interview with senior members of our Finance team which includes an onsite assessment for you to complete on this day. Our standard recruitment process typically lasts around 3 to 4 weeks, 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 click here to learn more.

Please note that, whilst we embrace AI to innovate and improve processes, your role may involve confidential data that cannot be uploaded to AI. Therefore, it is important for us to assess your own skills and abilities, so we recommend that you do not rely solely on this technology to generate any application materials.

Visa Sponsorship

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.
