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 at the heart of 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 have opportunities to join our communities to share ideas and collaborate with other engineers.

We are open to flexible working arrangements to support your performance.

At Nationwide, we offer hybrid working where possible. Our approach supports meaningful in-office collaboration and learning, while also providing generous home working options. We value our time in the office for problem-solving, learning, and connection.

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

If you are outside Swindon or London, you will need to attend the office once a month for workshops, collaboration, and meetings.

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