The Role
The Manufacturing Test Engineering team at Block 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 design board-level and end-of-line test stations to test our products, including the following subsystem technologies: display, touch, NFC, audio, WLAN. 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 Block's hardware products.
Please note that this role is based in Singapore with frequent travel to Malaysia, Vietnam and China.
