Job

We can offer you the chance to help make the UK a safer place through innovation, working in partnership with government, defence, and law enforcement organisations on some of the most challenging data and technology problems out there.

We strongly encourage candidates of all different backgrounds and identities to apply. We are committed to building an inclusive, safe and supportive environment that allows everyone to do their best work. We are happy to support any accessibility or neurodiversity requirements that you may need during the recruitment process.

About Us

Weve been around for about ten years and grown from being a little‑known tech start‑up to creating our own community at the heart of the thriving and diverse tech and digital ecosystem of Greater Manchester. As part of our future journey were looking to create footprints in other areas of the UK, and in this instance around the Portsmouth and Salisbury Plains area.

Our name Naimuri is Japanese and simply means nai meaning not muri meaning overburden

These principles apply to every aspect of an organisation from technology, process and infrastructure, through to people, culture and leadership. This means that we empower our teams to do what they think is the right thing, giving them the skills and confidence to explore new ways of working, and to create a bias‑free environment, where all our people feel comfortable collaborating to deliver the finest ideas and solutions in an agile environment.

Our business is focused on 4 cornerstones, which shape and underpin the way in which we go about work and treat each other. These are:
Wellbeing, Empowerment, Perpetual Edge and Delivery.

People and culture are at the heart of Naimuri, so that collectively, we can realise our mission of making the UK a safer place to be.
