About the Role

Information about the Command

The role of Intelligence is to develop the right operations, which target and disrupt - by the most effective means - the offenders who seek to cause the highest harm to the UK.
A diverse directorate with a wide variety of unique functions and specialist skillsets in our ranks, some of which we deliver as the national provider for the wider Serious Organised Crime (SOC) system. From our niche technical capabilities, to our overseas network of International Liaison Officers (ILO) and our Tasking teams, there are many component parts which contribute to the efforts of the directorate and the National Crime Agency (NCA).

/*generated inline style */

Information about the Business Area

Intelligence Collection coordinates NCA collection capabilities against the NCA’s highest priorities. Intelligence Collection includes forensics, open source, covert human intelligence sources, undercover officers and technical collection capabilities. This includes responding to threats and exploiting opportunities relating to the use of electronic communications by Subjects of Interest using the various powers conferred within the Investigatory Powers Act 2016 (IPA). This is a dynamic and diverse arena with constant and rapid change, suiting those officers who thrive on near constant challenge.

Role Summary

An exciting opportunity has arisen to work in Technical Operations within the National Crime Agency (NCA).

As a Senior Officer, Technical Equipment Interference (TEI) Software Engineering, you will operate within a specialist team delivering direct support to complex, technically demanding operations. Working in a fast-paced environment alongside a range of Technical Officers, you will play a key role in enabling the successful delivery of operational taskings.

This role centres on the hands-on design, testing, and implementation of innovative software technical solutions to address real-world operational challenges. You will analyse data derived from technical capabilities to identify gaps, vulnerabilities, and emerging opportunities, applying your software engineering expertise to develop and deploy effective solutions that enhance operational capability.

/*generated inline style */
Role Description

As part of the TEI Development Team, you will contribute to shaping and delivering tactical technical responses in support of some of the UK’s most serious and complex operations. Your work will directly influence the effectiveness of operational outcomes by ensuring innovative and resilient technical software solutions are developed and deployed at pace.

Working closely with the Technical Operations TEI Team, you will provide end-to-end support across the lifecycle of operations - from initial requirements gathering and solution design through to deployment, optimisation and ongoing support. You will ensure that deployed capabilities remain effective, adaptable and aligned to evolving operational objectives, while also assessing and refining deployment mechanisms to maximise impact and reliability.

In addition, you will collaborate with Law Enforcement and Intelligence partners to identify emerging threats, trends and capability gaps. By maintaining a strong awareness of technological advancements, you will help ensure the NCA remains at the forefront of innovation, continuously adapting its technical software capabilities to respond to a rapidly evolving threat landscape.

Prior experience in the TEI environment is not required, as the successful candidate will receive full training and support to develop the necessary TEI knowledge and skills.

Due to the nature of the role, the postholder will be required to travel regularly to the Leicester office if based in Gillingham or Bristol, and occasionally to other NCA sites and operational locations. Some locations may not be easily accessible by public transport. Applicants must therefore hold a valid driving licence (UK or international) that permits them to drive a car in the UK, or be willing to obtain one within 12 months of commencing in the role.

Please be aware that candidates who progress beyond the application sift will be required to attend an in-person interview at our head office in Stratford, London.
