Electrical Design Engineer

  • San Francisco, CA, United States
  • Full-time

Company Description

Since we first opened our doors in 2009, the world of commerce has evolved immensely – and so has Square. After enabling anyone to take a payment and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldn’t work together. So we expanded into software and started building integrated, omnichannel solutions – to help sellers sell online, manage inventory, run a busy kitchen, book appointments, engage loyal buyers, and hire and pay staff. And across it all, we’ve embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow all in one place.

Today, we’re a partner to sellers of all sizes – large, enterprise-scale businesses with complex commerce operations, sellers just starting out, as well as merchants who began selling with Square and have grown larger over time. As our sellers scale, so do our solutions. We all grow together.

There is a massive opportunity in front of us. We’re building a business that is big, meaningful, and lasting. And we are helping sellers around the world do the same.

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 of our products to the world, our hardware footprint continues to expand.

Square's mission demands complex electrical designs including integration of multiple payment technologies, RF and near-field communication (NFC), batteries, displays and multiple CPUs. 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 have end-to-end product ownership since electrical engineers at Square advise on program concepts, design hardware, perform certifications, work with RF, work on sustaining, and more. Square electrical engineers gain a full view of all the electrical work required to ship a product. Experience gained in this role will be broad.


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"

Qualifications

You have:

  • 5+ 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
  • On-site factory experience with contract manufacturers
  • 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
  • Experience automating lab instruments with Python
