PS/17/259 Domain Driven Developer Requirement 3

Tender description

Who Speclialist Work With They will work with (by providing expert advice) the IT Service Creation delivery squads in DVLA which includes software engineers, test engineers, business analysts and also the Senior Management Team. What Specialists Work On The DVLA requires a specialist to provide industry best practice experience and patterns in the development of Domain Driven Design and the subsequent implementation of those patterns using Java 8 on public cloud infrastructure. The specialist will be an expert on the creation of System of Record data stores using the CQRS/ES patterns. DVLA require the expert to assure the implementation of these systems meets industry best-practice. We anticipate this may take up to twelve months but acknowledge that this could take longer. Outputs delivered within this twelve months are required to be built to industry best-practice implementations. Where the Work Takes Place DVLA, Morriston, Swansea, SA6 7JL Early Market Engagement This is one of three similar requirements for Domain Driven Design. The IT Service Creation teams needs to able to deliver digital services at pace and using the Command-Query Responsibility Segregation pattern with Event Sourced systems of record. The DVLA has little native experience of implementing these technologies at scale and the specialist will be critical to the timely delivery of transformed digital services to the industry. The IT Service Creation team needs to be able to deliver digital services at a much greater pace than they currently do. The services they develop must have a much lower cost of operation than they currently do. The basic operating model for IT Service Creation has been asserted and we are now beginning to prove that it will work. This has exposed a substantial gap in experience and knowledge. We intend to have around 3-4 squads of mix-capability engineers working on the Vehicles Transformation programme. Working Arrangements The nature of the work dictates the location.
