Electrical Engineer

  • Shenzhen, China
  • 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. From the Square Card Reader for NFC and chip cards, Square Stand, Square Terminal and Register, our family of devices is growing - and this is only the beginning. As we introduce more and more of our products to the world, our hardware footprint continues to expand.

Square’s mission demands electrical designs that include integration of multiple technologies, RF, near-field communication (NFC), batteries, displays, multiple CPUs, and more. All of this must coexist with security, reliability, and low cost at high-volume manufacturing. 

Square is a global company with offices around the world, and our hardware team is no exception. We have team members in various locations in East Asia and North America.
