A valued member of a diverse team, you’ll follow subjects of national security investigations by foot and by car. Your observation skills, quick thinking and ability to fit into your environment means you’ll be able to make a big contribution.

We have developed some tasks that reflect the nature of the work of our Mobile Surveillance Officers to enable you to assess your suitability for the role.
