Square Electrical Design Engineer in San Francisco, California
Our hardware team builds the tangible connection to all that is square. With the Square Card Reader and the introduction of Square Stand, our family of devices is growing in terms of technologies and payment types—and this is only the beginning. As we introduce more and more of our products to the world, our hardware footprint expands.
Square’s mission demands ever increasingly aggressive electrical designs that now include near-field communication (NFC), custom in-house designed silicon, and increasingly complex CPU core designs. All of this must coexist with the demands of high active security (tamper detection), power management, and low-cost manufacturability in high quantities. We are looking for a passionate electrical design engineer who craves these challenges.
