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:

• 3+ 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.
• Fintech mindset: Understanding of data security and the high stakes of financial transaction flows.
• Self-starter: Experience working on “zero-to-one” projects where processes need to be built, not just followed.
• 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.
