API QA Analyst

Summary

We are looking for an API QA Analyst to join in our team: a small, cross-functional quality team embedded with a development squad. You will be the specialist for validating APIs, integrations, service contracts, and backend business rules before they affect user-facing channels. You will work alongside the QA Lead, Functional Testers, QA Automation Engineers, Mobile Testers, and Performance Testers, bringing a service-layer quality lens to every release and helping the team detect integration defects early.

Key responsibilities

• Review API specifications, integration designs, data mappings, business rules, and interface dependencies.
• Design positive, negative, boundary, authorization, idempotency, error-handling, and data-validation scenarios.
• Maintain traceability between requirements, endpoints, test cases, and dependent systems.
• Develop and execute API tests for REST, SOAP, GraphQL, or event-driven interfaces as applicable.
• Validate requests, responses, status codes, headers, schemas, payloads, authentication, and business rules.
• Build reusable API collections and automated test suites using tools such as Postman/Newman, REST Assured, Karate, SoapUI, or Playwright.
• Prepare test data, stubs, mocks, and environment configurations needed for integration testing.
• Use logs, traces, database queries, and correlation identifiers to isolate integration failures.
• Log defects with complete request and response evidence, expected behavior, and downstream impact.
• Report API coverage, execution status, defect trends, and integration risks to technical and non-technical stakeholders.

Qualifications:

• Bachelor's degree in Computer Science, IT, Engineering, or a related field, or equivalent experience.
• 3-5 years of software testing experience, with at least 2 years focused on API and integration testing.
• Hands-on experience with Postman, SoapUI, REST Assured, Karate, or a comparable API testing tool.
• Strong understanding of HTTP/HTTPS, REST, JSON, XML, status codes, headers, and authentication methods.
• Experience validating data using SQL and tracing transactions across integrated systems.
• Basic scripting or programming skills in Java, JavaScript/TypeScript, Python, or Groovy.
• Experience using OpenAPI/Swagger specifications and source control using Git.
• Familiarity with Agile/Scrum and the software development lifecycle.
• Experience with contract testing tools such as Pact or schema validation frameworks.
• Exposure to microservices, message queues, event streams, webhooks, and service virtualization.
• Experience integrating API tests into CI/CD pipelines.
• Knowledge of API security testing concepts and performance checks.
• ISTQB or relevant API testing certification.
