We are looking for experienced consultants with Enterprise Architecture, Systems Engineering, Delivery Management and Business Consulting skills in the Law Enforcement sector. You may have worked on large scale capability development or business transformation programmes or in front line or operational roles for our customers.


In joining us, you will have the opportunity to deliver projects ranging from technical de-risk and early stage proof of concept through to design assurance and business change on large scale programmes. As part of a small, rapidly growing business, you will also have an opportunity to shape the business as we grow and take responsibility for mentoring and supporting junior staff.

Current opportunities includes business and systems analysts, systems engineers and solution architects, and delivery managers.

Principle One is a consultancy and you may occasionally be required to travel to client sites around the UK. Project work may require working at customer or partner offices for periods of time. For long term roles outside of London we work with our staff to find the right mix between the demands of the project and work life balance.


We offer a competitive salary and benefits including comprehensive healthcare and a discretionary bonus scheme, and can offer part time and flexible working arrangements.


Due to the nature of the role and the work we undertake with our clients, you should be a British Citizen, and will be required to complete Baseline Personnel Security Standard checks ahead of employment. Existing security clearance (SC or DV) is an advantage but not essential and you should be willing to apply for security clearance.
