Job Description

Backend Engineer

* Are you a problem solver?
* Are wanting to push the boundaries of engineering by building a clean, scalable and secure platform that millions of people use?
* Do you want to create innovative solutions that empower people to achieve their life goals?

Our engineering interests

- Security

Open banking means that we work with lots of different data and data sources, and each brings its own security challenge. Our approach is very much of ‘privacy by design’: programming from a secure platform, using encryption and embedded PHP libraries to shape the lines of defence around customer data. We don’t just want to use the best security practices available – we want to develop them ourselves, placing privacy (and people) at the heart of everything we do.

- Payments

APIs present a brand new way of doing bank-to-bank payments. The free transfer of money is something that would reshape the entire finance industry – and we want someone to help build the technology that can facilitate it. This means, when it comes to payments, you’ve been there and done it; you’re well-versed in fraud monitoring, and are passionate about protecting the customer at all times.

Show me the tools!

We use PHP 7.2, Go, Symfony 4.1 and Nginx. We’re also using Typescript, Node JS, and some python. We are big believers in BDD and TDD. If we feel that a tool is not the right one for us, we can always consider switching to something else. Nobody likes legacy. When we say greenfield, we mean it.

Our mission

Put simply, we want to improve the daily lives of millions of people – ourselves included. By making finances easier to manage, everybody can be good with money.

How we’re getting on

Bud is an early stage business, but we’re growing fast. 2018 saw the team expand from 17 to 70 (yes, really) - and the pace is only picking up. Alongside this, we’ve won some notable awards, and work closely with HSBC to ensure our tech gets out there.

Who we are

We’re a diverse group of people. With backgrounds ranging from data science to music production, more than 80% of our team come from outside the world of finance – providing us with a unique perspective as we help consumers feel more in control of their lives. For us, an interest in people comes first; finance follows.

What we’re doing

The apps and infrastructure we’re building are designed to place the power of personal data back into the hands of normal people.
Picture this: a world where your bank knew you were paying too much for your gas bill and could switch you to a more suitable provider, or understood your savings targets and could automatically find you a better deal. That’s what we’re working towards.

What excites us

We love independent people who lead by example. We also love our R&D days: two days dedicated to your own experimental projects and learning, happening every 6 weeks.

Open banking? This is our bread ’n’ butter, a massive game changer not just for the industry but for people like you! It essentially allows companies like us to come up with new and exciting ways to help you make the most of your banking data.

Rental Recognition? This an awesome new service we’re working to make your rental payments contribute to your credit history, just one of the many different ways that we’re helping people to jump onto the housing ladder.

Sound like your kind of challenge?



Bud gives 25 days holidays, all bank holidays and we think the festive period in December should be spent relaxing so we give the whole team time off between Christmas & New Year's Eve!


As part of our company pension plan, we offer contributions to match up to 5% of your salary.


You’ll be provided with a brand new MacBook or PC, and any computer accessories you need so you’ll have the best tools for the job!

Learning & Development

As part of our commitment to helping people grow, we have opened the opportunity for people to have up to £500 per annum of learning and development opportunities funded by Bud

Hours & flexibility

Our core hours are 9:30 am to 6 pm. However, as part of our high-performance team, you'll benefit from the flexibility to manage your own day optimising the way you work so you can be at your best.


We’re big on keeping Bud a social team, so Christmas and Summer parties can be a big deal. We also put on quarterly events and have a social committee organising things like sports events, music gigs and after-work meet-ups!


Bud’s new office is a newly renovated space, specifically designed to our needs. Cool interior, breakout spaces, professional meeting rooms, brand new kitchen, loads of bike storage and a shower room for our part-time athletes. As our office is in The Bower WeWork there are also tons of events, not to mention, beverages on tap.
