Manufacturing Test Engineer | 生产测试工程师

Since we opened our doors in 2009, the world of commerce has evolved immensely, and so has Square. After enabling anyone to take payments 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, offer buy now, pay later functionality through Afterpay, book appointments, engage loyal buyers, and hire and pay staff. 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 in one place. Afterpay furthers our goal to provide omnichannel tools that unlock meaningful value and growth, enabling sellers to capture the next generation shopper, increase order sizes, and compete at a larger scale.

Today, we are a partner to sellers of all sizes – large, enterprise-scale businesses with complex operations, sellers just starting, as well as merchants who began selling with Square and have grown larger over time. As our sellers grow, so do our solutions. There is a massive opportunity in front of us. We’re building a significant, meaningful, and lasting business, and we are helping sellers worldwide do the same.

The Role

Square’s Hardware Team builds the tangible connection to Square. We started with a simple and elegant Reader that turns any phone or tablet into a mobile point of sale - and we continue to lead this category with advances in chip card and NFC technology. As we introduce more products, we will meet the needs of more and more sellers with stand-out hardware products, globally. Our hardware engineers are responsible for designing and developing world class hardware products. They understand the subtleties of user interaction, robust communication interfaces, and smart product design.

The Problems We Work On

The Manufacturing Test Engineering team at Square is responsible for making sure that the millions of hardware devices leaving our factories are built according to design and meet (or exceed) customer expectations. We’re a diverse group of engineers that use our unique backgrounds to solve challenging problems in our factories. We dabble in electrical engineering, software, mechanicals and data analysis to understand the design intent of our products and understand how we can translate it to scalable test plans. We are Jacks and Jills of all trades, and we thrive on having a deep systems-level understanding of Square’s hardware products.

Please note that this role will be based in Shenzhen, China or Taiwan.

• Become intimately familiar with Square's hardware products and manufacturing processes.
• Research technologies for our next-generation hardware products.
• Develop test plans and test-setup prototypes for new technologies.
• Work with Square’s Electrical Engineering group to ensure our products’ circuits are designed for testability.
• Work with Square’s Devices Software Engineering group to specify requirements for embedded test access and APIs.

• Excited to work on hands-on projects and to make things work in EE, software, and/or ME realms
• Experienced with hardware lab equipment for test, measurement (e.g. oscilloscope, power supply, DMM, etc.), and/or prototyping (Raspberry Pi, Arduino, 3D printing, powertools, etc.)
• Enthusiastic to apply methodical engineering problem-solving skills to dig into challenges that are outside of your expertise
• Able and willing to travel internationally 20% as needed

Even Better

• Familiar with board-level (SMT) and product-level (FATP) electronics manufacturing processes
• Experienced in reading and understanding electronics circuit diagrams and schematics 
• Experience performing analog measurements (RF, acoustic, optical, etc.) including calibration and control of systematic errors
• Experience managing contract manufacturing test engineering partners to drive GR&R, DOE, and Factory Test Dry Runs to prepare for prototype NPI builds
• Experience driving yield and cycle time optimizations
• Experience writing clear reports (Build Reports, Station Issue Lists/Material Issue Lists, SOPs)
