Integration QA Engineer

Company: Leadex Systems Employment type: FULL_TIME

About Leadex Systems:

Leadex Systems is a niche software consulting company and a long-time MuleSoft partner. We provide best-in-class API Management solutions in the Middle East and Europe. Our team of 66 like-minded professionals combines technical expertise with domain knowledge in digital banking, finance, and e-commerce. We embrace proactiveness, continuous learning, team spirit, and commitment to customer success.

About the role:

We are looking for a Back-end specialist who lives and breathes integrations. Your focus will not be on UI or internal microservices communication, but on the complex orchestration between our core platform and external third-party services.

Responsibilities:

• End-to-end integration testing: Plan and execute complex test scenarios for API flows, focusing specifically on how our system interacts with external third-party providers.
• Data integrity and mapping: Validate data accuracy and transformation as it moves across various external services and the MuleSoft/Salesforce ecosystem.
• Backend validation: Perform deep-dive testing of REST/SOAP APIs, ensuring error handling, rate limiting, and edge cases for third-party integrations are robust.
• Defect orchestration: Identify, document, and track bottlenecks and bugs, working closely with MuleSoft developers and Salesforce architects to resolve integration gaps.
• Process architecture: Since this is a "from-scratch" project, you will help design and refine the end-to-end testing strategy, including regression suites and integration workflows.
• Stakeholder collaboration: Engage directly with UK-based client stakeholders to align on integration requirements and provide transparent reporting on quality metrics.
