Technical Support Engineer

About the Team The In-Store Technology organization at DoorDash is committed to building products that help restaurants create exceptional experiences every day. We are a growing team of engineers and builders on a mission to transform hospitality operations. Within Integrations, we connect our in-store platform to point-of-sale systems so restaurants see accurate check data, spend, and service status alongside guest and reservation information. About the Role We're hiring a Technical Support Engineer focused on POS integrations. You'll manage and resolve complex integration support cases by leveraging technology, logs, and APIs to diagnose failures and maximise reliability for restaurants and POS partners.
