Company Description

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Job Description

Within Square's Hardware organization, the SQUID Platform Team provides the core OS that powers Square's Register and Terminal hardware products. Square takes pride in our product experience from manufacturing to end customer experience, and this team works closely with partner teams throughout the hardware and software product lifecycle, from hardware manufacturing to Android app teams. We work with external vendors on part selection and initial hardware bringup, with a focus on customizing Android for Square's state-of-the-art security posture. You'll report to our SQUID Platform Engineering Manager.

  • Improve our Android OS at the frameworks layer, designing features customized for Square's hardware and security needs
  • Develop and ship new features on our Android OS platform, launching across several products simultaneously

Qualifications

You Have: 

  • 5+ years software development experience

You May Also Have (but not required):

  • Experience bringing up Android OS on a new device or hardware platform
  • High-level understanding of Google's AOSP architecture
  • Have built the Linux kernel, and some experience writing Linux device drivers
  • Experience working with microcontrollers (GPIO pin states, interrupt handlers)
  • Experience adding, monitoring and parsing telemetry data to proactively resolve issues
