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 project:
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.
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 (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: 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.
We offer:
- Flexible work schedule.
- 31 days of vacation.
- 5 sick days.
- Sport compensation.
- Support with purchasing the necessary equipment.
