About Us

We are the Information Intelligence Group (IIG) of CACI UK, a specialist software consultancy providing new bespoke solutions to solve our customers' complex operational problems. As our business continues to grow, we are interested in speaking with an experienced Full Stack Software Engineer with expertise in Java to join one of our live projects within our Central Government team.

You will be designated a base office which could include Manchester, Bristol, Cheltenham, or Plymouth; however, we work in a hybrid fashion so you can choose how often working from the office or home. There is an expectation however to meet customers on a regular basis (typically bi-weekly).

The Opportunity

We have a wide variety of teams who support our customers on a range of interesting and complex projects, building new bespoke software solutions and providing them with up-to-date capability to meet their needs. As a Senior Software Engineer, you will join an Agile-focused team, gaining exposure to:

• Implementing software solutions including design, development, and testing


• Using a wide range of technologies, specializing in the use of open-source libraries and components


• Utilizing tools such as GitLab to build continuous integration pipelines, which help monitor and ensure software quality and security


• Deploying software systems to a mixture of environments, including public (AWS and Azure) and private cloud


• Full Software Lifecycle involvement: project concept formalization; requirements analysis and specification; architecture design; implementation and delivery; training and support; and software lifecycle and maintenance


• Leading teams and managing engagement with our clients (depending on experience)

The Fit

We are interested in speaking to Full Stack Engineers with commercial experience using Java, TypeScript, JavaScript, and React. You will also be comfortable working with cloud technologies, primarily AWS and Azure. Previous consultancy experience is useful but not essential.

Due to the industries we work in, all our team must be able to obtain security clearance. To qualify, you must be a British passport holder and have lived permanently in the UK for the last 5 years.
