For the next few years, we have exciting ambitions. That’s why we are looking for iOS & Android engineers who are inspired by developing a great m-commerce app, with an optimized and advanced user experience. We want to go further than just display products.

We are looking for a Senior iOS Engineer to work inside the Customer Journey Tribe, which is leading the strategy across the marketplace, focusing on the user experience, features and services on the Back Market app & platform. It will be a great opportunity to evangelize the native app in the tribe and help to grow the team & app features.


Thanks to your engineering skills, code & reviews process, you will also take part in a mobile engineering chapter, with talented iOS, Android, and QA engineers. You will learn, share, and improve all together, in addition to scaling up our mobile app’s architecture & delivery at Back Market.


Whether you're hooked on Swift, developing advanced UI with motion, or purely Core architecture, you will work efficiently and you will favour collaborative work by remaining open to new ideas.

This is who you are:

  • You are an engineer with more than 5 years of experience on iOS, with some apps released on the App Store or B2B, or some significant repos on GitHub
  • You know how to build Swift applications with solid architecture (MVVM-C or similar, multi-modules, dependency injection)
  • You understand the SOLID principles, but also acknowledge when KISS should prevail
  • You know how to design your code through technical conception before development
  • You know & use reactive programming (RxSwift, Combine)
  • You know how to deal with the challenges of asynchronous and concurrent programming (DispatchQueues, Swift concurrency) 
  • You know how to test your code and avoid regressions (Unit & UI tests). You collaborate with our QA engineers
  • You have a good understanding of an iOS app lifecycle and performance optimizations (app launch, app size, debug memory leaks, smooth UI, etc.)
  • You are curious and proactive about Swift and the iOS tech: SwiftUI (we plan to fully migrate starting 2022), property wrappers, result builders, functional programming
  • You know how to work with a team with advanced Git commands, Git-flow, and by making clean Pull Request & code reviews
  • Code is power: you like to code interfaces (no storyboard files) and advanced animations, without external libraries 

    • A meaningful job: through hard work, you will help avoid thousands of tons of electronic waste and fight against planned obsolescence. It counts!

    • An attractive salary, equity, multiple benefits (meal tickets, health insurance, etc...), parental benefits, #remote friendly company, relocation package, internal events, etc… 

    • Technical challenges all day every day: you will have the freedom to innovate and adopt new ideas!

    • Work with passionate experts who will share their knowledge and help you develop and grow! (Backademy, technical guilds, Meet-up & Conference)
