Overview

This is a hybrid role based out of our Leicester office.

Home. There’s no place like it.

And there’s no feeling like helping people create the joy of feeling truly at home. At Dunelm, that’s what we do. We’re the UK's number one choice for homewares because we make home life lovelier for our customers. And we’ve crafted a workplace that feels just as welcoming – where you can bring your ideas, be yourself, and feel right at home.

We’re looking for a Principal Cyber Security Engineer to lead and strengthen our Security Operations at Dunelm.

This critical role will take ownership of our Security Operations function and lead both our DevSecOps and SecOps teams, helping to drive a proactive security culture across the organisation. You’ll set the direction for how we build, operate, and secure our platforms, championing a proactive security culture across engineering and operations.

As our senior security technical lead, you’ll influence architecture decisions, strengthen our secure engineering practices, and embed robust controls throughout the development lifecycle. You’ll also drive improvements in detection, response, and operational resilience across all our technology platforms. This is a role for someone who wants to shape strategy, lead talented teams, and make a meaningful difference to how we protect and scale our business.

D&I statement

Dunelm is committed to becoming an inclusive business that is representative of our customers and locations. We recognise the value in diversity and welcome applications from all candidates regardless of age, race, religion, disability, gender or sexual identity, socio-economic background or education. We are committed to making Dunelm a place where everyone can enjoy a successful career and have systems in place to support all our colleagues. We are seeking applications from candidates who share our values and celebrate diversity in all its forms.

Our commitment to you

Accessibility allows everyone to have an equitable chance when applying and showing off their potential, which helps us create a more inclusive and diverse team that brings fresh ideas and perspectives.

Should you need it, we have an accessibility tool available in the top menu to support you when you’re completing your application. If you require any other reasonable adjustments during the application and assessment process, reach out to your recruitment partner.

Tech to the future

Meet John, our Chief Tech and Innovation Officer, who shares insights into the exciting things happening in tech, why Dunelm is his happy place, and his unique route into the tech world.

Work your way

We want our colleagues to feel at home wherever they work, so that they are comfortable and can be their best selves. In addition, we want everyone to feel connected to the business, our strategy and the teams they work with.

Where hybrid working is applicable, colleagues need to strike the right balance to fulfil both of these important factors. You will find the right mix of being at home, in the office & out in the business, bearing in mind business needs, job role and level of responsibility.

Wellbeing is more than just a buzzword here

From our Wellbeing Buddies and Mental Health First Aid training to our progressive parental leave, menopause policies and Colleague Support Fund, we're committed to supporting our colleagues in every area – and at every stage – of their lives. Through our partnership with the Retail Trust, everyone at Dunelm has free access to a 24/7 Virtual GP, as well as therapy and counselling, plus information, guidance and advice in all areas of financial, emotional and physical wellbeing.

Look in our toy box

Of course, you should never judge a business by its tech stack. But take a peek at the range of technologies our engineers and developers are currently playing with.

Keep on growing

Join us on the tech side and you'll have access to a huge array of learning and development opportunities, including a variety of internally created workshops and externally accredited courses. We also have a substantial tech-specific budget to fund e-Learning licenses, conference visits, resources, and qualifications, plus dedicated mentors, well-being buddies and a wide range of network groups to support you as you progress.
