Senior Software Quality Engineer, Quality Systems

  • San Francisco, CA
  • Full-time

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

Our hardware team builds the tangible connection to all that is Square. We started with a simple and elegant Reader that turns any phone or tablet into a mobile point of sale. Since then, we have expanded our hardware footprint to meet the needs of more sellers. Most recently, we introduced our first Android-based solutions: Square Register, the first fully integrated point of sale that enables people to start selling right out of the box, and Square Terminal, the all-in-one device for payments and receipts. You will ensure our sellers and their customers have a remarkable experience shaping our device software validation strategy for our Square hardware products.

You will:

  • Determine when our product software is good enough for our sellers by using your knowledge of product architecture and evaluate product risk during each phase of development, deployment, and use
  • Oversee the definition and execution of overall validation strategy, both manual and automated, for the platform software that ships on our hardware devices
  • Work with multiple development teams and organizations to influence the software architecture and integration across the stack (e.g. applications, system, and firmware)
  • Be a hands-on lead and help build a productive team by coaching engineers


You have:

  • 8+ years of verification, validation and software engineering experience
  • Developed validation strategy for a complex functional area or product
  • Experience working as a partner to development and product teams
  • Mentored other team members by providing technical guidance 
  • Experience validating and shipping a successful consumer electronics device
  • A high degree of curiosity, with experience creating creative techniques to discover hardware, firmware and software issues
  • Managed or partnered with contractors
  • Supported ongoing software releases across multiple products
