Why you’ll love this role
You will own quality across services that shape the customer experience during and after their order on StockX. Your responsibilities span the entire order lifecycle: from trade execution and delivery date calculations to managing cancellations, returns, and order page updates. You will also oversee customer support chat functionality, buyer-seller communications, real-time order history, and offer tracking. Furthermore, you will ensure the reliability of RBAC-enabled internal APIs and CRM integrations. Your testing will guarantee that customers have fast, accurate, and reliable tools to manage their orders at scale.
You will work across a rich set of systems: an internal agent portal, GraphQL APIs, event-driven Kafka pipelines, OpenSearch-powered order and customer search, the bid-ask-decorator service that surfaces market and offers/order history data to customers, the estimated-delivery-date service that powers delivery predictions across pre- and post-purchase flows, and a real-time chat platform that enables buyer-seller and agent communication.Our technical stack includes Amazon Web Services, GraphQL, Node.js, NestJS, TypeScript, React, CircleCI, Kubernetes, Harness, Terraform, LaunchDarkly, OpenSearch, Kafka, SQS, Redis, Postgres, and Datadog. You will test across all of it.
Our engineers and SDETs are empowered to own quality decisions, not just execute test cases. You will be expected to identify gaps, propose solutions, and present your work in team and org-level forums.
