Summary

At HMRC we are committed to creating a great place to work for all our colleagues; an inclusive and respectful environment that reflects the diversity of the society we serve.

We want to maximise the potential of everyone who chooses to work for us and we offer a range of flexible working patterns and support to make a fulfilling career at HMRC accessible to you.

Diverse perspectives and experiences are critical to our success and we welcome applications from all people from all backgrounds with the experience and skills needed to perform this role.

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.

Digital Support and Innovation (DSI) sits within HMRC's wider Fraud Investigation Service (FIS) responsible for the department's civil and criminal investigation work. FIS ensures that HMRC has an effective approach to taking on the most serious tax evasion and fraud.

Working across Law Enforcement and government, DSI 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 full stack developer in the Technical Exploitation Development (TXD) team plays an integral role in Her Majesty's Government's fight against serious and organised crime, supporting investigations totalling hundreds of millions of pounds each year.

Our modern tech stacks vary between products (some examples can be found under the essential criteria), so the team is encouraged to adopt new technologies and specialisms within each stream.

The team recognises that several technical specialisms are required to support the work, but we don't expect any one individual to possess them all. We are committed to providing mentoring, in addition to an extensive training package to upskill successful applicants.
