Job Description
The Role:
Let’s talk numbers. When it comes to UK retail, it’s hard to find a bigger name. We sell thousands of items an hour and are expanding our e-commerce business by the second. For anyone in Tech, this is the place to learn. To grow. And to thrive.
What You’ll Take On:
The successful applicant will work on the development and support of our gift card systems, whilst helping maintain and support our other mainframe applications. The role involves all aspects of the development lifecycle and requires flexible and innovative individuals with a positive attitude.
Operating across more than 72 countries worldwide, Next and our Total Platform partners process transactions through a diverse range of payment methods, including gift cards, e-vouchers, credit & debit cards, ApplePay, Klarna, and PayPal. In the UK, we also provide various credit options, which are either developed completely in-house or powered by bespoke third-party software seamlessly integrated into our infrastructure. Ensuring our £2 billion platform remains secure, modern, and fit for purpose is the responsibility of our Payments & Credit Technology Team.
You will provide analysis and programming skills in core languages, review and support the gathering of user requirements, and produce sustainable and efficient solutions following Agile methodologies. You will design, code, maintain and support business critical systems which are used 24/7, 365 days a year. You will develop in both a batch and online environment adhering to relevant standards and working closely with our user community to provide both technical and non-technical advice.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
