About the role

  • Working closely with Jimmy (our Lead iOS Engineer), and Javi, Andrii, Orcun, Arne, Lieneke, Daniil, Rosa, Dmytro, Azat and Paulo (our senior iOS developers) on all things related to our app.
  • Be responsible for implementing new features, improving existing features and maintaining the day-to-day operations of our iOS App.
  • We're product-first; meaning you won't just work within the iOS team, you'll be embedded in a dedicated Product Pillar team, each owning a distinct part of the user journey. Day-to-day you'll work closely with PMs, designers, and engineers across disciplines. It's a genuinely cross-functional setup: PMs, designers, and engineers working together from problem to solution, because the best product decisions happen when technical perspective is in the room early.
  • Proactively improving the maintainability, resiliency and extensibility of our app, addressing technical debt when needed or even better, preventing it when it makes sense.

Requirements

  • At least 5+ years of hands-on experience with iOS development
  • Experience working in an agile team environment.
  • A pragmatic approach to problem-solving, and an absence of fear when it comes to tackling big challenges in UI, architecture, or refactoring that 5-year-old piece of legacy code.
  • A strong iOS development background, we work with Swift, but we still have some legacy Objective-C code, so we would love it if you are also familiar with that.
  • Extensive experience with large apps published in the App Store.
  • In-depth knowledge of UIKit, SwiftUI and experience building complex user interfaces.
  • Experience with writing and debugging multithreading code. We use GCD, Combine, and the latest Swift Concurrency.
  • Realm knowledge.
  • Experience with Swift Package Manager.
  • Experience using Xcode instruments to optimize app performance and memory consumption.
  • Experience with setting up and maintaining CI/CD pipelines. We use Fastlane and Github actions.
  • Experience leveraging AI tools (e.g., Claude Code, ChatGPT Codex) to improve development speed, code quality, and debugging efficiency.
Benefits
  • A yearly free flight or train ride to a random location! Give our Teleporter a spin here.
  • A shiny new MacBook to work your magic on.
  • Hybrid working, our way. Work from home and the office, we ask everyone to be in the office 2 days a week. It’s how we stay flexible, focused, and meaningfully connected in person.
  • An extensive home office set-up — everything from noise-canceling headphones to a standing desk.
  • 30 days of vacation (for adventures or sitting on the couch, it's up to you)
  • Two paid Culture Days for days that are important to you but not recognized by the official Dutch calendar.
  • The option to switch up your zoom background by working from another country for up to 8 weeks a year.
  • A personal development budget for that curious mind of yours!
  • A pension plan to help you save for those around-the-world retirement trips.
  • Delicious daily team lunches.
  • Awesome monthly parties, as well as team trips away.
  • A lively office in downtown Amsterdam, with travel costs reimbursed.
  • Free Polarsteps Travel Books to contain all your far-flung adventures.
