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.
