[Hiring] Integration QA Engineer @LEADEX CY LTD

Role Description

You will be joining a greenfield Fintech project developed from the ground up for a UK-based client. You will work within a high-performing cross-functional team including a Project Manager, Salesforce Lead & Developers, and a dedicated team of MuleSoft Developers.

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 (payment gateways, KYC providers, banking APIs, etc.).

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: 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.

Qualifications

• 3+ years of QA experience with a heavy focus on Back-end, System, and Integration testing.
• Proven track record of testing third-party service integrations (External APIs, Webhooks, etc.).
• Expert-level proficiency with Postman, SoapUI, or similar API testing tools.
• Strong SQL skills for data verification and backend state validation.
• Understanding of data security and the high stakes of financial transaction flows.
• Experience working on "zero-to-one" projects where processes need to be built, not just followed.
• Confident spoken English (B2+ level) for active participation in meetings with the British client.

Requirements

• Familiarity with MuleSoft, Salesforce, or the UK Fintech ecosystem is a significant plus.

Benefits

• Flexible work schedule.
• 31 days of vacation.
• 5 sick days.
• Sport compensation.
• Support with purchasing the necessary equipment.
