Intro

Our SumUp office in Cologne is now hiring for the position of iOS Developer.

The Job

You’ll shape the core experience of merchants who are using the iOS App on a daily basis.

In the first few weeks, you'll dive into the code and learn how to create clean, composable components in our codebase. You'll use this knowledge to start developing and refining features. You'll learn how we write tests, how we manage bluetooth communication, and how we keep performance tip-top.

In the first three months, you'll develop major features that impact our merchant base. You'll work closely with product and design departments to build features that are maintainable, usable, and beautiful. You'll help us re-think problems we've solved before in a different way as requirements evolve.

By the end of your first year, you'll have a wealth of knowledge about our complex problem domain, as well as its implications in the interface and in the backend – and how to manage it in a clean way. You'll have launched numerous features in the iOS app as well as in the iOS SDK.

Main requirements

  • You are comfortable with Objective-C and the iOS system frameworks.
  • You are curious about Swift, good knowledge would be a plus.
  • You know what to test, why to test it, and how to write flexible tests that won't break.
  • You care about user interaction, usability and of course, making the interface beautiful.
  • You strive for clean code, but also know how to make your "shortcuts" easy to delete in a crunch.
  • You love coding and take the time to reflect on all aspects of your implementation, be it the frameworks, languages or processes.
  • You also know how to get things done on the command line.
  • You are not afraid to ask for help or to use Google when something is beyond your grasp.
  • Your precise communication skills make working in a distributed team effective and efficient.
  • Technology excites you and you strive to learn something new on a daily basis!

Perks

  • The Mobile Team: You'll be with people who care about mutual learning, keeping our technical knowledge up-to-date, and discussing ideas that contribute to not only the company's success but keeping everyone connected to the wider tech community.
  • Opportunity to attend tech meetups and conferences with the team (especially if you're giving a talk!).
  • Convenient location in the heart of Cologne.
  • All the startup swag you expect: Xbox, unlimited coffee, and a shiny MacBook Pro.
  • Our office has a strong sense of community; we get together regularly for sports, Karneval, and drinks.
  • Our global team comes from 30 different countries creating a fun, international environment.
