About us

We are the leading global mobile point-of-sale (mPOS) company, with major offices in Berlin, Sofia, and São Paulo. We started out five years ago and built our payment service from scratch to shake up the industry and wake up the entrepreneur within everyone. We created a unique device that pairs with the smartphone in your pocket, allowing small merchants to accept card payments anywhere. Beyond our original hardware, mobile and web apps, we have gone on to develop a suite of APIs and SDKs for integrating SumUp payments into other apps and services. We recently launched a brand new contactless device, which makes paying by card easier than ever before!

Our SumUp office in Berlin is looking to hire for the position of Junior Frontend Engineer.

In this role, you'll work with a small cross-functional team to build tools that help hundreds of thousands of small businesses thrive. By shipping code early and often, you'll see the impact of your work on our merchants' daily lives right away. You'll collaborate with experts in product, design, and operations to deliver mission-critical internal and external features that power the SumUp ecosystem.

We work on a number of different projects that span technologies, systems, and processes. A few of the technologies we're leveraging on the web at SumUp include React, Webpack, GraphQL, Apollo, Jest, Enzyme, Storybook, Next.js, Emotion, Node, and Docker.

You'll fit in perfectly to our team if:

  • You love coding, learning and are open-minded to trying different tools and technologies.

  • You are both open to mentorship and know how to teach yourself new things.

  • You have experience or interest in writing tests for your code.

  • You care a lot about the end users of your software and building a great user experience.

  • You already have some programming fundamentals but are looking for a way to reach the next level -- we can do that together!

  • In general, technology excites you and you strive to learn something on a daily basis!

In this role you will:

Here are some of the things you'll be doing at SumUp.

  • Ship code multiple times per week as part of a cross-functional, agile team.

  • Develop new features and components in our merchant-facing Dashboard, a modern React app running on Node.js.

  • Work with your teammates in Product and Design to formulate and conduct experiments that shape data-informed decisions and increase our conversion rate in our ecommerce shop.

  • Launch new products and features by creating the corresponding UI experience in our merchant-facing application.

  • Share your knowledge with other developers through pair programming and receive mentorship in return.

  • Help us continue to develop our open-source projects and culture.

Here are a few things you could work on at SumUp:

  • Our merchant-facing React app, replete with all the modern tooling. The application provides functions like analytics, employee management, ecommerce, onboarding, and referrals. Many cool features are in the pipeline surrounding Point of Sale, product catalogue, and more.

  • Our public website, built with React and Next.js and modern tooling (Webpack, Prettier, Jest, Enzyme). Today we enable our marketing, business development, and communications teams to build custom pages with React components. Tomorrow we are building more tools to improve editor productivity, handle our expanding product offering, and educate merchants on growing their business

  • Our design system and component library, built in React, using Emotion for css-in-js. These components can be used in all our different web applications. We use Storybook as a component workbench and Docz to generate public-facing documentation.

  • And many more, like our SumUp for Developers tools, ecom gateway, open source integrations, internal applications, and greenfield projects. We also use Docker and Kubernetes.

If you're interested in diving into the platform or getting your hands dirty with DevOps tasks, you're encouraged to extend your impact to those areas as well.

Your profile:

These are some of the qualities we'd love to see. Don't be concerned if you don't fit 100% of the requirements, we are looking for the best overall team member.

  • Comfortable with HTML and CSS

  • JavaScript / programming fundamentals

  • Command line basics (git, npm, ssh, etc.)

  • Attention to detail and empathy for your end users.

  • Ability to communicate fluently about technical topics in English.

  • Proactive attitude and eagerness to learn and improve

  • No prior professional experience required

We would love if you've also worked in programming languages besides Javascript, but it's not a requirement. This is fundamentally a full stack role! We look for people who are excited to go beyond their comfort zone and learn new things.

Benefits:

  • A dedicated annual budget for attending conferences and advancing your career through further education. We encourage you to speak at conferences and give talks.

  • Weekly Lunch and Learn session, where the local engineering team exchanges ideas over company-sponsored lunch.

  • Dedicated time every week for side-projects and open source initiatives.

  • Semi-annual offsites, where the engineering teams from Berlin, Cologne, Sofia, and São Paulo gather together.

  • We have a close, welcoming and international community. We get together regularly for brunches, cocktail nights, football, office events, AMA sessions, training, German classes, and yoga classes.

  • Numerous other benefits such as Urban Sports Club subsidy, Corporate Pension Scheme, Kita placement assistance, relocation assistance, and a gorgeous place to work in the heart of Berlin at Alexanderplatz.
