Key Responsibilities

Functional & Regression Testing

• Design, develop, execute, and maintain comprehensive test cases, test scenarios, and test scripts based on business requirements, user stories, and technical specifications
• Perform functional, regression, integration, smoke, and end-to-end testing on web applications, APIs, mobile applications, and backend services
• Validate system behavior across browsers, devices, and environments to ensure consistent user experience
• Identify, log, prioritize, and track defects through to resolution using defect management tools (Jira, Azure DevOps), including clear reproduction steps and severity classification
• Perform data validation and database testing—verifying data integrity, stored procedures, and query results against expected outcomes (SQL proficiency required)
• Execute user acceptance testing (UAT) coordination, supporting business stakeholders in validating system readiness

API & Integration Testing

• Test RESTful and SOAP APIs using tools such as Postman, Newman, or REST Assured—validating request/response payloads, status codes, headers, authentication, error handling, and edge cases
• Validate integration points between microservices, third-party systems, and payment gateways (M-PESA, card networks) to ensure data flows correctly across boundaries
• Create and maintain API test collections with parameterized data, environment variables, and automated assertions for repeatable validation
• Test message queue workflows (Kafka, RabbitMQ) by validating message production, consumption, ordering, and dead-letter handling

Test Automation

• Develop and maintain automated test scripts for regression, smoke, and critical path testing using frameworks such as Selenium, Cypress, Playwright, or Appium
• Integrate automated tests into CI/CD pipelines (Jenkins, GitHub Actions, GitLab CI) to enable continuous testing on every build and deployment
• Build and maintain test data management strategies, including test data generation, masking, and cleanup for repeatable test execution
• Contribute to the team’s automation strategy—identifying high-value manual tests to automate based on frequency, risk, and regression impact
• Maintain and improve the test automation framework, including page object models, utility libraries, and reporting dashboards

Security & Compliance Testing

• Participate in security reviews of new and existing systems, products, and services—validating that security requirements are implemented correctly
• Perform security-focused testing aligned with OWASP Top 10: injection flaws, broken authentication, cross-site scripting (XSS), insecure direct object references, and other common vulnerabilities
• Use security testing tools (OWASP ZAP, Burp Suite, SonarQube SAST) to identify vulnerabilities in web applications and APIs
• Collaborate with IT security teams to validate access controls, role-based permissions, data encryption (at rest and in transit), and session management
• Assist in testing compliance with regulatory standards applicable to financial services (data privacy, PCI-DSS, audit trail requirements)
• Document security findings with clear risk ratings, evidence, and recommended remediation actions

Performance & Load Testing

• Design and execute performance, load, and stress tests using tools such as JMeter, Gatling, k6, or Locust to validate system behavior under expected and peak transaction volumes
• Establish performance baselines and monitor for regressions across releases—measuring response times, throughput, error rates, and resource utilization
• Collaborate with backend and infrastructure teams to identify and resolve performance bottlenecks before production deployment

Reporting, Process & Collaboration

• Produce clear, concise test reports including test execution summaries, defect metrics, risk findings, and go/no-go recommendations for releases
• Maintain traceability between requirements, test cases, and defects to ensure complete coverage and audit readiness
• Participate actively in Agile/Scrum ceremonies—sprint planning (estimating test effort), daily standups, sprint reviews, and retrospectives
• Collaborate with developers on defect triage, root cause analysis, and defining acceptance criteria for user stories
• Contribute to continuous improvement of QA processes, testing standards, and quality metrics across the team
• Mentor junior QA team members and promote a quality-first culture within the engineering organization
