What they need


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 a Full Stack Software Engineer with experience in Java to join one of our live projects within our National Security Government team.

Due to the nature of the work, the role will be based predominately from either our Bristol office (next to Temple Meads station) or from customer site in Cheltenham.

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 Software Engineer, you will join an Agile focussed team, gaining exposure to:

  • Implementing software solutions including design, development and testing
  • Using a wide range of technologies, specialising in the use of open-source libraries and components
  • Utilising 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 formalisation; requirements analysis and specification; architecture design; implementation and delivery; training and support and software lifecycle and maintenance
  • Lead teams and managing engagement with our clients (depending on experience)

The Fit At present we are interested in speaking to Full Stack Engineers with commercial experience using a range of languages / technologies. Previous consultancy experience is useful but not essential.

Due to the industries we work in, we require all our team to be able to obtain high level security clearance. To qualify for this, you must be a British passport holder and have lived permanently in the UK for the last 5 years. Culture & Benefits We take great pride in taking care of our talent, providing a highly dynamic, inclusive and team-led environment where everyone can thrive. We value every member of our business, and strive to be a place you’re excited to work. Our market-leading package of benefits reflects this.

WELLBEING - Free 24/7 counselling helpline and employee assistance programme

WORK YOUR BEST - City-centre offices across the UK, combined with flexitime and at home working

LEARN & GROW - Assigned Career Coach to holistically guide development

SOCIAL - Get-togethers throughout the year, from ad hoc socials to the Summer Party in London and annual awaydays

ONSITE ALLOWANCES - expenses for lunch and drinks
