Integration QA Engineer focusing on back-end and integration testing for a UK Fintech project, collaborating closely with stakeholders and developers on complex API flows.
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.
Requirements:
- 1+ years of QA experience with a heavy focus on Back-end, System, and Integration testing.
- Integration specialist: Proven track record of testing third-party service integrations (External APIs, Webhooks, etc.).
- Technical toolkit: Expert-level proficiency with Postman, SoapUI, or similar API testing tools.
- Data proficiency: Strong SQL skills for data verification and backend state validation.
- Communication: Confident spoken English (B2+ level) for active participation in meetings with the British client.
- Bonus: Familiarity with MuleSoft, Salesforce, or the UK Fintech ecosystem is a significant plus.

- Flexible work schedule.
- 31 days of vacation.
- 5 sick days.
