About the team

As we are expanding internationally at a high pace, you will be at the centre of our business development - this is a very exciting time to join Catawiki!

Our Engineering teams are interdisciplinary: you will cooperate directly with Backend, Frontend, iOS, and Android Engineers, and together you and your team are responsible for all functionality of our Catawiki apps and our web app within the team’s product domain.

You'll ensure that your features work well on all recent iOS and iPadOS devices, and recent OS versions. You keep track of system performance, and optimise it where needed.
In addition, you will use A/B experiments, agreed upon with your Product Manager and User Experience Designer, and backed by data analysis, to add product features and deliver the best user experience on the platform.

• You have experience with testing frameworks - XCTest, XCUITest, Quick & Nimble, snapshot testing, and/or Swift Testing.
• You have an understanding of good programming principles - SOLID, DRY - and have a good problem-solving approach and mindset.
• You can discuss and propose API designs with engineers with a focus on user-friendliness and long-term benefits.
• When building features, you consider performance, testing, security, localisation, accessibility, and observability.
• You know how to monitor and manage an application in production: you build it, you run it, you love it!
