The Technical Exploitation Development (TXD) team plays an integral role in His Majesty's Government's fight against serious and organised crime, supporting investigations totalling hundreds of millions of pounds each year.
The team manages a diverse and rapidly increasing product portfolio, ranging from development of covert tools for mobile device data acquisition, computer and network exploitation, building custom radio frequency hardware, to the implementation of cutting-edge data visualisation platforms.
Collaboration and capability sharing are critical to our mission so working alongside other Government and Law Enforcement agencies will ensure that no two projects nor two days are ever the same in this role. The team is recognised across the LE and UKIC community as deep matter experts in a range of complex technical specialisms including software engineering, hardware electronics, radio frequency, computer and network exploitation, and reverse engineering.
To enable the rapid prototyping and production of bespoke capabilities, the team is split into two distinct functions:
• Engineering is responsible for managing the full stack development and testing of all bespoke solutions. This could include; developing tools to normalise, interrogate and visualise large datasets, command and control systems, to producing plugins and modules to extend functionality of commercial and in-house built tools.
• Exploit Development is responsible for conducting security research before producing specialist tools that assist in the exploitation of digital devices, encrypted communications and networks.
All staff across both functions are expected to code and test, to produce capabilities as part of the software development lifecycle. Engineers are required to work and collaborate closely within both functions.
Our modern tech stacks vary between products (some examples can be found under the essential criteria), so the team is supported to adopt new technologies and specialisms.
Person specificationThe role is ideal for experienced developers and engineers who enjoy problem solving and are driven to overcome complex technical challenges to produce solutions that enhance our sensitive capabilities. You will be expected to:
• Carry out research and development of new equipment, tools and techniques to counter the threat, risk and harm posed by serious organised criminals.
• Work in a team of software engineers and exploit developers, ensuring services are built, tested, delivered, and operated as required.
• Lead on the rapid development of user-driven prototypes to identify technical options and inform architectural approaches.
• Ensure systems are robust, scalable, open and secure to deliver a high-quality digital user experience.
• Follow best practice guidelines and seeking to improve those guidelines.
• Work with your team to provide estimates on user stories/task/requirements.
• Collaborate as part of a team to design components for larger systems.
• Provide guidance, technical operational support and training in the installation and use of developed tools and techniques for deployment by investigation officers.
• Work as part of a skilled team sharing ideas, but also take the initiative and work independently with little supervision.
• Ensure all work is carried out within the requirements of the legal framework to be compliant in the law enforcement and legislative process.
• Provide direction and participate in code review, pair programming and mentoring to support junior engineers.
• Break a problem down into its component parts to identify and diagnose root causes as well as troubleshoot and identify problems across different technology capabilities.
• Build relationships and collaborate with external law enforcement agencies, private industry and academia.
• Communicate complex technical problems to stakeholders with clear communication that's understood by all.
