Senior iOS Developer

PLN 14,000 - 23,000 + VAT (B2B)

Hi! 👋

We’re codequest, a boutique software house made up of an all-star team of polyglot engineers, creatives, and industry specialists who are truly passionate about technology and innovation. We are small by design, humble at heart (why we keep the ‘c’ small in our name), and focused on creating a great company vibe while working on the coolest projects for our clients worldwide.

You can find us right in the center of Warsaw, just a minute's walk from Metro Świętokrzyska, which makes it conveniently located for the morning commute. Or, if you prefer, you can work remotely from home or anywhere you want. 😀

We are about connecting the dots - not standalone milestones. That’s why we want you to help us grow by joining our awesome mobile team of iOS developers.

  • We always try to choose the right tool for the job, but our main stack is MVVM with the use of RxSwift, Moya, Alamofire, Snapkit, Swinject, Quick and Nimble for testing - you can master this currently popular stack
  • We're eager to try and learn new technologies but want stable apps as well, so we're slowly but steadily incorporating SwiftUI and Combine into some of our projects
