Would you like to work for the Ministry of Defence?

Defence Business Services (DBS) is one of the largest shared service organisations in Europe that provides a wide range of corporate services, to over 1.2 million end users, including serving and past military and families, as well as MoD civil servants and industry. DBS delivers large scale administration and smaller specialist services to enable the wider MOD to focus on its core aims, maintaining the UK's Defence and Security. Services include Human Resources, Pay, Veterans, Finance and Procurement.

• Our Vision - To support UK defence customers with outstanding service every time.
• Our Mission - Together we will proudly support Defence, continuously improving and delivering flexible, timely, sustainable and value for money services that underpin the whole force and enhance operational capability.

DBS is committed to creating a great place to work for all our colleagues. We are building an inclusive culture and respectful environment that reflects the diversity of the society.

We want to maximise the potential of everyone who chooses to work for us through opportunities to develop your skills and experience. We also offer a range of flexible working patterns and support to make a fulfilling career accessible to you and offer a Civil Service pension with an average employer contribution of 28.97%. Where your role permits, we support a blended working approach alternatively known as hybrid working.

Where business needs allow, some roles may be suitable for a combination of office and home-based working. This is a non-contractual arrangement where all office-based employees will be expected to spend a minimum of 60% of their working time in office, subject to capacity and any required workplace adjustments. Requirements to attend other locations for official business, or work in another MOD office, will also count towards this level of attendance. Applicants can request further information regarding how this may work in their team from the Vacancy Holder (see advert for contact details). Defence Business Services cannot respond to any questions about working arrangements.

DBS has recently undertaken a review of its operational locations in the North West, and have consolidated all activities in Norcross, Blackpool. A further move, to the new Government Hub at Talbot Gateway in Blackpool, is scheduled to take place in 2027.

You will join a team in DBS Digital, Information and Technology (DIT) responsible for exploiting and administering the DBS Oracle Cloud Infrastructure (OCI) platform, in support of Civilian People business needs. Working closely with engineers, developers, other architects and the wider Civilian People Change Delivery Services, your focus will be on designing and improving the OCI platform to enable DBS to provide its Civilian People services. This includes support to the Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) technologies enabling and extending the Oracle HCM Cloud Software-as-a-Service (SaaS) HR, Payroll and Expenses system MyHR.

This role will also involve architectural oversight of a MODCloud iACE (Microsoft Azure) tenant hosting the public-facing Discover My Benefits website.
