What we can offer you

We don’t settle for people that can just do the job, we look for people that are constantly trying to push the boundaries and improve what we do. This is what makes CACI a great team to be a part of.

This team is at the cutting edge of cloud engineering within CACI and are constantly innovating. The success of this team is down to our ability to push the boundaries with what is possible and to continually improve ourselves and our services.

Innovation is hugely important to us and we guarantee everybody in the business gets to spend 5% of their time innovating and training. If you are an innovative thinker and like to challenge the norm, coming up with new ways of doing things, then you will be surrounded by likeminded people at CACI.

Progression

We understand that your career progression is important to you. Unlike many organisations, promotions happen twice a year at CACI. This gives you more opportunity to progress. At CACI people get promoted on merit, when they are ready. This means that your career is completely in your own hands and there is never a ceiling for your progress.

Everyone’s career path is different. We welcome people exploring different areas and trying out new skillsets. Just because you start off down one path doesn’t mean you are committed to it indefinitely. At CACI you have the freedom to carve your own career path.

Flexibility

The key to our success is our teamwork and collaboration and that tends to work best when we are all in the office working together. That said, we fully appreciate that everyone leads busy lives and we can’t always be in the office. This is why we embrace flexible working. Covid-19 has changed the way we work forever, and we’ll update our flexible working policy as the situation stabilises.

Development

Your development is key and is a top priority for the team. We offer 3 types of training: externally run consulting courses, externally run bespoke courses and internal courses. Everyone has different training requirements which means everyone has their own training plan. A bespoke training plan will be created for you when you join.

Benefits

We have a range of benefits on offer to support you. We have a comprehensive list of schemes ranging from pension plans to health and wellness policies, in addition you can opt into a selection of flexible benefits to meet your personal needs.
