Hybrid (x2 days on site/ x3 Work from home)

If you are looking for an exciting opportunity to make a difference with great job satisfaction in a fast, dynamic, and thriving team, then join our Integration Platform team at Nationwide. We are central to the society’s tech strategy and the focal point for our current and future Kubernetes platform.

As a MongoDB Database Administrator, you will work in project teams designing, building, and maintaining MongoDB databases and infrastructure to deliver strong business solutions. You will be involved at all stages—from design and build to supporting both non-production and production environments. We foster a learning culture at NBS, encouraging ongoing development and skill enhancement in relevant technologies. You will also have opportunities to join our communities to share ideas and collaborate with other professional engineers.

We are open to flexible working arrangements to help you perform at your best.

At Nationwide, we support hybrid working wherever possible. This approach helps us build rewarding relationships, bringing colleagues together across our UK estate while also providing generous access to home working. We value the time spent in the office for problem-solving, learning, and connection.

For this role, you'll spend at least two days per week, or if part-time, 40% of your working time, based at our London, Swindon, Northampton, or Bournemouth offices. Further details will be provided by your hiring manager if your application is successful. More about our hybrid approach can be found here.

If you are outside of Swindon and London, you will need to attend these offices once a month for workshops, collaboration, and meetings.

High application volume may lead us to close this advert early, so we encourage prompt applications.

What you’ll be doing

You will collaborate with delivery teams to build optimal solutions for Nationwide, using your technical leadership and SME knowledge to advise, build systems, and troubleshoot within the MongoDB space. You will guide less experienced engineers and help create fit-for-purpose designs to meet team objectives.

Occasional on-call work may be required.
