Product Quality (QA) Engineer

San Francisco Bay Area

We augment human productivity and happiness through automation.

For many people, coffee is a daily ritual that sets the tone for the rest of their day. Cafe X offers consistent, premium quality at affordable prices by designing, manufacturing, and operating robotic coffee bars that serve specialty coffee precisely brewed to the roaster’s specifications. 

By automating the mechanical aspects of making coffee, our robots enable our Coffee Bar Specialists to focus on delivering a superior customer experience, setting the standard for human-robot collaboration in hospitality, one cup of coffee at a time.

Backed by Craft Ventures, Khosla Ventures, Social Capital, Felicis Ventures, and The LAUNCH Fund, Cafe X is rapidly growing the founding team to launch more locations, scale manufacturing, and develop next-generation products.

Currently, we operate three San Francisco locations: The Metreon, 578 Market Street and One Bush Plaza. We support our communities by partnering with local roasters such as Equator, Ritual and Intelligentsia, highlighting the Bay Area’s best coffee beans.

We’re looking for diverse, pragmatic, and talented individuals who take initiative, remain humble, and aren’t afraid to get their hands (literally) dirty.
