Electrical Design Engineer

  • 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. 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 increasingly complex electrical designs that include integration of multiple payment technologies, RF and near-field communication (NFC), batteries, displays, multiple CPUs, and more. All of this must coexist with security, reliability, and low-cost, high-volume manufacturing. We are looking for a passionate electrical design engineer who craves these challenges. You will report into our Electrical Design Engineering lead.

You will:

  • Design circuits for Square’s hardware products
  • Collaborate with firmware, mechanical, and factory test engineers, developing cohesive, elegant solutions
  • Design low-power, low-cost embedded systems optimized for volume production from “cradle to grave”
  • Travel internationally 5~15%

Qualifications

You have:

  • 2+ years experience as an electrical engineer in embedded systems
  • Experience designing and shipping high-volume consumer products
  • Expertise in the hardware lab with test, measurement, and prototyping
  • Expertise in developing schematics and leading PCB layout activities
  • Familiar with standard communication interfaces such as SPI, USB, I2C, RS232
  • Hands-on experience designing for EMC and debugging associated issues
  • Strong skills in power management and low-power optimization
  • Extensive on-site factory experience with contract manufacturers
  • BS in electrical engineering or related field
  • Experience with electrical simulation (i.e. SPICE, electro-magnetic, etc.)

Even Better:

  • Experience in board-level analog design
  • Familiarity with Altium Designer
  • Experience with ARM processors
  • Understanding of near-field and RF design fundamentals (i.e. NFC, Wi-Fi, Bluetooth, etc)
  • Experience writing embedded firmware
  • Ability to automate lab instruments with Python
