Senior QA Engineer (m/f/d) - Add-on
Full-time Mid-Senior LevelJob Overview
As part of SCAYLE’s Add-on Unit, we design, build, test, fix, release, and monitor modular, plug-and-play e-commerce solutions for the SCAYLE commerce engine, solutions that enable additional capabilities for our tenants, drive conversion, enhance operational efficiency, and ensure seamless integrations across diverse customer setups.
Within this context, our QA Engineer plays a key role in safeguarding the quality and stability of these add-ons throughout their entire lifecycle. As an essential member of the unit, the QA is responsible for validating complex FE/BE interactions, ensuring integration reliability, and supporting the team in delivering robust, production-ready features.
What you will do:
Testing complex frontend and backend integrations between SCAYLE, Add-ons, and external systems (e.g., marketplaces, partner services, etc).
Performing comprehensive API testing (CRUD operations, error validation, contract behavior) using tools like Postman.
Executing and maintaining E2E, regression, and functional tests across multiple customer scenarios and configurations.
Debugging cross-system communication by analyzing logs, payloads, and service interactions to identify root causes quickly and accurately.
Using monitoring tools such as Datadog to validate system performance, trace flows, and detect inconsistencies or failures after releases.
