Senior Engineer, Mobile Developer Experience

  • San Francisco, CA
  • Full-time

Company Description

We believe the economy is better when everyone has access. When everyone has room to grow. No one should be left out because the cost is too great or the technology too complex. We started with a little white credit card reader but haven’t stopped there. We’re empowering the independent electrician to send invoices, setting up the favorite food truck with a delivery option, helping the ice cream shop pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. We’re here to help sellers of all sizes start, run, and grow their business—and helping them grow their business is good business for everyone.

Job Description

Mobile Developer Experience (MDX) is responsible for building and providing all necessary infrastructure and tools to ensure Square’s mobile development can continue to be fast and efficient at scale.  We're looking for folks who are excited to problem solve and find solutions that empower hundreds of mobile developers to move more quickly than our competitors.

Engineering efficiency is particularly important for Square’s ability to continuously ship high quality software, so we strive to ensure our development tools enable developers to ship their features with speed and confidence. This is a high force multiplier, cross-functional team aiming to enhance the development experience for all mobile developers within Square. 

You will be part of the team responsible for owning the entire development stack (build system, build tools) and integration with CI. You will improve the development process to allow our engineers to ship as quickly and effortlessly as possible. You’ll be working primarily on the mobile platform infrastructure focused on our largest scaling codebase, Square’s Point of Sale applications, but we expect the results of the team’s work to be applicable to other Square applications.

What will you do:

  • Innovate to amplify the efficiency of our mobile developers to develop, build, test, and release high quality apps to our merchants.  

  • Identify key performance bottlenecks in the development experience including the build system, IDE integrations, testing frameworks, and pull request workflows.

  • Help define the scope and the priorities of the team by identifying opportunities to decrease build times, reduce system complexity, and improve the developer experience

  • Optimize the performance, reliability, and usability of our CI pipeline

  • Own the success of your team's projects, and deliver quantifiable results on schedule.

Qualifications

You have: 

  • BA/BS degree or equivalent practical, working experience

  • Extensive knowledge of build systems (e.g. Bazel or Blaze a big plus, for Android candidates, Ant, Maven, Buck, Gradle, Pants and for iOS candidates, Carthage or CocoaPods) and CI tools (e.g. Circle, Travis, Jenkins) 

  • Experience for supporting build or CI systems infrastructure (ideally at scale) 

  • First hand experience building apps for Android/iOS

  • Excellent software engineering aptitude and the ability to provide technical mentorship and guidance
