Our SumUp office in Berlin is looking to hire for the position of 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 merchant's 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. This is fundamentally a full-stack role.
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 not only love coding, but also take the time to reflect on the benefits and drawbacks of your tools, be they frameworks, languages, or processes.
- You strive for clean code, but also know how to make your "shortcuts" easy to delete in a crunch.
- You know what to test, why to test it, and how to write meaningful tests.
- You have experience with or interest in Functional Programming techniques.
- You know how to make pragmatic programming decisions in a complex codebase.
- You care about user interaction, usability, and of course – making the interface beautiful.
- In general, technology excites you and you strive to learn something on a daily basis!
Hundreds of thousands of business owners rely on SumUp to drive their business. You'll shape some of their core experiences: from their first impression on our website, to the web-based features that make them loyal to our platform. 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 aim to inform data-driven decisions and to increase our conversion rate in our ecommerce shop.
- Launch new products 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.
- Take initiative in pushing projects forward, while validating and communicating your ideas with the team.
- Help us continue to develop our open-source projects and culture.
- Assist in hiring and recruiting efforts to continue to build the team you are working in.
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 do CI with Docker and Jenkins, and will soon be working with Kubernetes as well.
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.
- Understanding of web performance and page speed optimization techniques
- Command line fundamentals (git, ssh, editing a file on a remote server, reading logs, etc.)
- Ability to implement design specs precisely
- Ability to communicate fluently about technical topics in English
- Proactive attitude and product mindset − you own what you build!
- Data Driven mindset on your decisions.
- 2+ years professional experience
- 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. In the past we've gone to Bulgaria, Greece, and a castle in the German countryside.
- We have a close, welcoming and international community. We get together regularly for brunches, cocktail nights, football, office parties, German classes, and yoga classes.
- 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.
- All the startup swag you expect: kicker table, unlimited coffee, and a shiny MacBook Pro.

We're looking forward to meeting our next teammate! You'll be asked to provide the following information when you apply:
- Why you think you'd be a good fit for this position.
- One of your favorite coding challenges you encountered in the last two years: what was it about, how you tackled it, and what you learned. Technical details encouraged!
