Salary

We reward staff based on technical excellence and not years of experience, so it's important to us to speak with you to see which grade you would fit into - it's not always obvious from a CV! Your interviewer will spend time during your first interview speaking with you about how your skills and experience map against our grades, and discuss a salary band so that you know early what you can expect if you receive an offer from us. The technical interview will provide a deeper assessment of your skills against your mapped grade which ultimately determines whether you receive an offer and the exact salary.

Location

We are based in the centre of Cheltenham in a stunning new build contemporary office, 5 minutes walk from the local shops and cafes.

Additional Details 

Our interview process is quick and to the point: if you look like a good fit for the role, we'll schedule a brief call to discuss it in more detail and answer any questions you may have. If that goes well, we'll arrange a technical interview to understand your level of experience. We aim to get back to you with an answer within a couple of days of the technical interview.

Please note, due to sensitivity of the role, successful applicants must hold an active Developed Vetting security clearance.
