We’re Recruiting For Police Staff Investigators

These roles sit within one of London’s 20 Major Investigation Teams (MITs), at the heart of the Met’s response to the most serious and complex crimes. MITs lead investigations into homicides and, where required, other serious criminality and high-risk missing person cases, working at pace to deliver justice and protect the public.


As part of an MIT, you’ll play a key role in progressing major investigations under the direction of experienced Senior Investigating Officers (SIOs). You’ll work alongside Police Staff Investigators (PIP Level 2) and Detective Constables, within a structured team led by a Detective Chief Inspector and supported by Detective Inspectors and Detective Sergeants. Based at one of four Specialist Crime hubs, your work may take you anywhere across London as investigations develop.


This is a challenging, fast-moving, and highly rewarding operational role. You’ll be trusted to carry out a broad range of investigative activity, manage evidence and information to the highest professional standards, and contribute directly to cases as they move through the criminal justice system. The work is unpredictable by nature, and flexibility is essential — but for those motivated by tackling serious criminality and making a real difference, it offers exceptional professional satisfaction and development.


Specialist Crime aims to create an inclusive and welcoming atmosphere and culture and an environment where all our people feel a strong sense of belonging and are able to reach their full potential.


Applications for job share and part-time will be considered, although the full range of duties (early & late shifts and weekend working) will be required.
