We offer a range of entry level opportunities for graduates, interns and placement students.

Our graduates start with us in July or September and will take part in a 10 week programme to develop a mix of business and technical consulting skills. This combines training sessions with on the job learning and the opportunity to work with one of our customer or partner organisations on real life problems from day one. As we are a small, rapidly growing business, you will have the chance to contribute to our internal processes and systems as we grow. You will also be assigned a career mentor to support your career development.

We are seeking applicants with a strong academic track record, ideally in a STEM subject but will also consider graduates from other subjects with a strong interest in working in the Law Enforcement sector. We offer a competitive salary and benefits that include comprehensive healthcare and a discretionary bonus scheme. We are based in Vauxhall and you can expect to split your time between working in the office and remotely.

We also offer 10 week summer internships and one year placements to students who are part way through their degrees. We welcome applications from a wide range of degrees. Interns and placement students have access to the same training opportunities as our graduates, with placement students then having the opportunity to work as part of our delivery teams following initial training.

Due to the nature of the role, all applicants should be eligible to apply for UK government security clearance. To find out more or apply please contact

I joined Principle One in September 2021 after completing a Masters in Crime and Forensic Science at UCL and an undergraduate degree in Experimental Psychology at Oxford. I’ve always been fascinated by the law enforcement and security sector, but also wanted a job where I could apply the academic and analytical skills I acquired during my studies. When I came across the business consultant role at Principle One, it seemed like the perfect fit – a company based within the field I was so interested in, but with a focus on innovation, technological advances and making long-term positive changes to the sector.
