Senior Android Developer

letgo's the largest app to buy and sell locally, with over 100M downloads and hundreds of millions of listings added by users. Named one of Wired’s “Hottest Startups” and among 2016’s “Best Apps” by Google, letgo’s the second fastest growing app in America since its 2015 launch. Business Insider calls letgo “the go-to app for selling your stuff” and it’s been featured by The New York Times, The Today Show, Mashable, Fast Company, The Wall Street Journal, Fortune and hundreds of others worldwide. It’s the only app with artificial intelligence and image recognition that make posting something for sale as simple as taking a photo. Users can easily browse local listings, chat instantly in the app and view each other’s profiles, ratings and reviews.

Based in our New York and Barcelona offices, our team of over 165 represents more than 20 nationalities. Fueled by our diverse expertise, letgo’s goal is to build the largest marketplace of its kind in the world. We’re looking for people who are as passionate as we are about creating something our users love and - just as importantly - who are excited by the challenge.

We’ve built a company for people who want to do impactful work, surrounded by great people. We have a well-defined, mature culture — and we’re always making it better.

Our team of Android engineers iterates fast to deliver new features to our beloved users. We build lots of features, test them and decide what to keep, improve or discard based on our data analytics and user research.

If you join our Android team, you will help solve different types of problems:

  • Improve buyer and seller communication by giving them tools built over our rock-solid WebSocket chat.
  • Let people earn some money by understanding the value of the goods that are scattered around their homes.
  • Make the user experience as easy as a snap.
  • Make letgo a safer place for buyers and sellers.

To get there, you'll need:

We're looking for experienced Android engineers that know when to cut corners and when to schedule a refactor. Candidates should be open to communicate and explain their decisions to the team and should be able to work hand to hand with designers, backend engineers, product managers and data engineers to build an awesome product.

We're looking for people who are able to ship features fast but keeping the quality of the code high. Over 50% of our codebase is written in Kotlin, but existing features are written in Java. We use RxJava and Dagger.

You should be able to read, understand and suggest improvements in our code as well as write the necessary tests to be sure that the features that you deliver are good to be shipped. Familiarity with analytics and monitoring tools is a plus.

letgo perks:

  • Competitive salary and stock options
  • Beautiful, new office in the heart of Soho and along the beach in Barcelona
  • Robust relocation package
  • Massage therapy (Barcelona office)
  • Fully stocked kitchens
  • Team-building activities
