Senior SDET - API Test Engineer

• Design and build automated test suites for APIs supporting payments, FX, wallets, ledgers, and remittance systems.
• Integrate testing into our CI/CD pipelines to provide quick feedback and maintain stable deployments.
• Develop contract tests from OpenAPI specifications to validate integrations between microservices.
• Monitor and report non-functional metrics like latency, error rates, and throughput alongside SRE teams.
• Test distributed systems for concurrency, idempotency, retries, and consistency with backend engineers.
• Maintain and improve automation tools for schema validation, regression testing, and SLA compliance.
• Utilize Generative AI tools to streamline test case generation and data fixture creation while preserving test quality.
• Investigate root causes during production incidents or test failures and collaborate with engineers to resolve issues.
• Promote shift-left testing by improving test documentation, tooling, and collaborative quality standards.

• Develop and enhance automated testing frameworks using tools such as Postman, REST Assured, Karate, or custom-built solutions.
• Create comprehensive test scripts to cover positive, negative, and edge cases for RESTful APIs.
• Automate critical tests including pre-deployment smoke tests, post-release regression checks, and performance monitoring for key services.
• Test integrations across internal systems (authentication, ledgers, FX, risk) and external partners (banks, PSPs, and other service providers).
• Manage test cases and maintain version control, ensuring alignment with evolving API specifications and SLAs.
• Build observability into testing processes through logging, metrics, dashboards, and alerting for test failures.
• Maintain and manage test environments, including mock services and test data, ensuring consistency and reliability.
• Partner with engineers to suggest improvements in performance, API design, and overall test coverage.

• Minimum of 4 years in test automation, specializing in API and backend testing.
• Solid understanding of REST APIs, HTTP protocols, authentication, and response validation.

• Proficient in programming/scripting languages like Go, Java, or Python for developing test utilities.
• Familiarity with API standards like OpenAPI/Swagger and automated contract validation.
• Strong background in writing modular, reusable, and maintainable test cases.
• Experience working with CI/CD tools (e.g., Jenkins, Bitbucket Pipelines).
• Understanding of distributed systems, asynchronous processes, retries, and service orchestration.
• Detail-oriented with strong skills in documentation, traceability, and reproducible test execution.

• Experience testing payment systems, remittance platforms, or other financial APIs.
• Familiarity with PostgreSQL or MySQL for database testing and transaction verification.
• Basic knowledge of performance testing tools like Locust, Artillery, JMeter, or Gatling.
• Exposure to GitOps-style testing workflows.
