Your impact at SumUp
You'll shape some of the core experiences of our merchants: 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:
- Write pragmatic, testable code that works on different devices, OSes, and browsers.
- Work with a cross-functional team to ship on a weekly basis.
- Contribute to our React component library and build new features in our merchant-facing SPA.
- Collaborate with product and design departments to build maintainable, usable, and beautiful features.
- Share your knowledge with other developers through pair programming.
- 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.
Our tech stack and projects
- Dashboard: Our merchant-facing web application, which provides merchants with analytics, reporting, employee management, signup, virtual terminal, and more. This application uses Angular 1.6, Webpack 3, Lodash, d3, and is formatted by Prettier. We're porting this application to React. You'll help us implement new features as part of your cross-functional team, as well as contribute to decisions on architecture and implementing best practices.
- Website: Our website is the first thing merchants see before they decide try SumUp, and you will help us implement beautiful designs in that show off our awesome product. This project is also moving from Jekyll to React, to enable people in Sales, Marketing, and other departments to create and update pages using React components and pulling data from our headless CMS (Contentful).
- Universal React component library and style guide: We're also compiling all our shared components between our website and web apps into a React UI library, which we plan to open source soon.
- Various other web projects, as well as your own projects and initiatives.
- 2+ years prior professional experience
- Expert knowledge of HTML, (S)CSS, and experience with React
- Experience building a non-trivial Single Page Application (SPA) (Angular or React preferable)
- Linux basics (git, ssh, editing a file on a remote server, etc.)
- Experience with data / content modeling and thinking in a reusable, component-oriented way
- Experience implementing accessible and responsive designs according to pixel-precise design specs
- Ability to communicate fluently about technical topics in English.
Bonus: Experience with Node and server-side debugging (or ability to learn).
- Dedicated budget for attending conferences.
- Weekly Lunch and Learn session, where the local dev team exchanges technical ideas over company-sponsored lunch.
- Stay creative! Spend your Friday afternoons exploring a side project of your choosing.
- We do at least one off-site every year, where the tech teams from Berlin, Sofia, and São Paulo gather together. In the past we've gone to Bulgaria and Greece.
- Our lean processes allow us to ship new features and functionality on a weekly basis.
- Infrequent regular meetings – most days you'll do a standup and get to work.
- We have a close, welcoming and international community. We get together regularly for brunches, cocktail nights, football, office parties, German classes, and yoga.
- All the startup swag you expect: kicker table, beer in the fridge, 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
- Share a recent coding challenge you encountered, how you solved it, and what you learned
- You can also choose whether to include a CV, a link to your Xing/LinkedIn, a link to your github, tech blog, or portfolio – whatever you think will give us the complete picture!
If your application is selected, our hiring process has four steps:
1. Short coding quiz (à la "Fizz buzz") which will take you 15-45 minutes.
2. Phone call to talk about position, get to know you, and answer your questions.
3. Verbal technical interview in our office where you can meet the team.
4. A day of pair programming in our office in Berlin on a React app.
Please be aware that our process involves interviewing on-site, so you should be prepared to come meet us during this process.
