Discover what it’s like to work in a compliance role that makes an impact. Could you help us shape a stronger, fairer future? Your next career move starts here.
HMRC is the UK’s tax, payments and customs authority and we have a vital purpose: we collect the money that pays for the UK’s public services and help families and individuals with targeted financial support.
HMRC’s Fraud Investigation Service (FIS) is responsible for the department’s civil and criminal investigations.
FIS provides HMRC with an effective investigation arm to enforce the Department’s compliance policies. This enables the Department to deliver against the strategic responsibilities across all the taxes and duties it administers. This includes complex offshore evasion, international smuggling of illicit excise goods, exports of controlled weapons and technology, labour market abuses, VAT and Self-Assessment repayment frauds and a host of other fraud attacks targeted at the tax system.
FIS is home to a wide range of people with a variety of skills and professional backgrounds - including accountants, cybercrime specialists, criminal justice professionals, tax professionals and operational delivery support teams to name but a few. We use a range of powers and approaches to protect funding for UK public services, investigating the most harmful tax cheats and ensuring nobody is beyond our reach.
Covert Operations, Digital Exploitation (CODE) sits within FIS. Working across Law Enforcement and government, CODE provides investigative tools and covert techniques to front-line investigations and works with key partners to develop and provide access to new technology and systems to enable investigators to respond to serious and complex tax evasion and crime.
Job description
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.
Our tech stacks vary between products (some examples can be found under the essential criteria), so the team is encouraged to adopt new technologies and develop specialisms through guided support and training.

• Provide guidance, technical operational support and training in the installation and use of developed tools and techniques for deployment by investigation officers.
• Ensure all work is carried out within the requirements of the legal framework to be compliant in the law enforcement and legislative.

Essential Criteria:

• Experience of working in an agile software development or exploitation role focussing on user-centred design.
• Experience to demonstrate identifying user requirements, ability to design software, write secure code and implement testing methods.
• Experience of Continuous Integration (unit testing, TDD, Jenkins, Git).
• Experience with version control systems.
• Experience of working with tools for API, performance, accessibility and security testing.
• Demonstrate an awareness of information security and the types of security controls that can be used to mitigate security threats within solutions and services.
