Would you like to join the talented team that is crafting the system that makes this possible?

Wallapop takes pride in having an open culture, where every opinion matters, and everybody can contribute in many different ways. We believe that we don't hire people to fit in a job description.

We hire people to find the best way to produce the most valuable work that they can do.

Each guild holds weekly technical meetings to discuss the state of the code, and decide what actions have to be taken in order to it continuing being maintainable, readable, and scalable.

With more than 8 million searches per day, more than 60k items sold per day and a catalog of several tens of millions of products, Wallapop is the biggest second-hand marketplace in Spain with more than 10 million unique visitors per month. 

We’re looking for an enthusiastic and proactive colleague to join us a an iOS Tech Lead

Our mobile experience is a priority for us. Some of the interesting things we are currently doing include using Swift and RxSwift for asynchrony; modularization and other techniques to reduce compile times; and evolve an app used by millions with several teams working on it at the same time.

The day to day involves

  • Leading and collaborating on taking technical decisions with the team
  • Working hand in hand with the team, like being involved with the product team and communicating with other wallapop Tech Leads
  • Cooperating with Engineering Managers in order to offer learning & growth opportunities to the iOS team

  • Working with Agile Methodologies like SCRUM and Kanban; Translating problems into actionable solutions that can be implemented by the team given the day to day restrictions/challenges
  • Actively work on improving the hiring strategy and working together with the hiring team
  • Being proactive and helping to get any problem solved. Pro-activity inside your team is the key to keep going further.

The Challenge

With a 6 years old code base and 8 iOS developers pushing code everyday to the same repository, we have quite a few challenges, and we're looking for someone that can work:

  • Developing new features and maintain a more than 2M daily active users app, with a low crash session rate (99% crash free users)
  • Facing a fast changing project. We are moving from a monolith app to a modularized one, which includes fun with CocoaPods, development pods and static libraries
  • Rewriting remains of Objective-C (14%) into Swift, as Chris Lattner would be proud of
  • Maintaining a clean architecture using different patterns, MVP, repository, coordinator, etc.

We are looking for someone with

  • Positive and proactive attitude, excellent problem solving and critical thinking
  • Outstanding prioritization and delegation skills.
  • Excellent communication skills, high adaptability and eager to learn
  • Able to receive and provide feedback (both technical and people focused) effectively and in a constructive and emphatic manner
  • Open minded team player with the capacity to work with different types of profiles beyond the iOS chapter and Engineering team
