Overview of the job

DMIs will play a critical role in developing the intelligence picture on a range of threats impacting upon HMPPS, enhancing existing intelligence products as well as developing their own analysis.

The post holder will be responsible for providing strategic and tactical intelligence analysis and products which will look across prison and probation contexts at ‘high priority’ offenders, offending groups and operational security vulnerabilities across HMPPS.

They will be working within DMIU, which acts as the Centre of Excellence for Digital Investigation across HMPPS. Occasional travel is likely and will include prison establishments and specialist intelligence units and hubs, as well as law enforcement partners’ offices.

A background in analytical work (any discipline) would be an advantage but is not essential; training in the suite of Digital Tactics will be provided.

Furthermore, this role will require the post holder to partake in specialist training and accreditation which will be provided and would be responsible for supporting the DMIU Function in their tactical delivery. As such, the post holder will have: an active interest in technology and communications as required to support the delivery of the current policy (PSI 30/2011 – to be updated) in line with Forensic practices detailed within the ISO 17025 requirements and PSI 27/2015 – to be updated)


This is an exciting opportunity to take up a key role within DMIU, which was created to support the key deliverables of the Directorate of Security (DoS), strengthening control systems and the processes for which the Director of Security is responsible. It was created to bring a range of tactical provision for exploiting illicit digital devices and illicit communications into one place, so that joined up and comprehensive services may be provided to a diverse range of local, regional and national customers dealing with digital threats affecting HMPPS.

It is accepted that the existence of mobile devices in custody can be a facilitating factor in the continuance of crime by offenders involved in Serious Organised Crime, other criminal activity such as corruption and counter terrorism, and can undermine the safety and security of prison regimes, the rehabilitation of offenders and the safety and security of the public. Law Enforcement partners have experienced the need to ensure all criminally-focused investigations are able to fully exploit available digital sources of intelligence, a capability which DMIU has built in parallel.

The post holder will also require strong communication skills to engage with a wide range of consumers of DMIU Services at all levels within HMPPS, with Law Enforcement partners.
