Senior QA Automation Engineer at Zojatech Technology Limited – Lagos

Zojatech Technology Limited is recruiting a Senior QA Automation Engineer in Lagos to own the automation strategy across Android and iOS applications, APIs and backend systems. This hybrid position involves three days in the office and two days working remotely each week.

QA strategy and test planning

• Build and implement risk-based QA plans that prioritise critical user journeys, APIs, backend integration and regression testing.
• Review requirements, user stories, acceptance criteria and technical designs to identify gaps and improve testability.
• Develop test plans, scenarios, test data and traceability, and choose suitable cases for automation.
• Collaborate with developers to strengthen early quality checks, unit and integration testing.

Automation framework development

• Design, implement and maintain reusable automation frameworks for mobile and web applications and APIs.
• Build mobile automation using Appium, WebdriverIO or comparable tools; automate API tests with Postman/Newman, Playwright or similar.
• Automate smoke, integration, regression and end-to-end tests while managing environments, data and diagnostic reporting.
• Review test automation code, establish engineering standards and reduce flaky or duplicated scripts.
• Apply exploratory and manual testing where hands-on investigation adds more value than scripted checks.

Application and API quality

• Test Android and iOS applications across devices, OS versions, screen sizes and network conditions.
• Validate backend APIs, authentication, authorisation, data integrity, error conditions and transaction workflows.
• Test disrupted connections, application state transitions, permissions, session expiration and recovery scenarios.
• Plan performance, stability, compatibility and accessibility assessments and coordinate security-focused checks.
• Use SQL, logs, network traces and debugging tools to investigate defects and verify system data.

CI/CD and team collaboration

• Integrate automated suites and quality gates into Git-based CI/CD pipelines and release processes.
• Distinguish product failures from environmental or test-script issues and communicate release readiness, risks and coverage gaps.
• Support post-release checks and translate production problems into preventive test coverage.
• Work with product, design, development and DevOps teams to track, prioritise and reproduce defects.
• Mentor QA engineers, improve test documentation and monitor coverage, reliability, regression time and escaped defects.

Essential requirements

• At least five years of software QA experience with substantial hands-on mobile and automation practice.
• Experience building and maintaining automation frameworks, rather than only running existing suites.
• Practical Android and iOS testing experience with automation expertise on at least one platform.
• Expertise in mobile automation tools such as Appium or WebdriverIO and API testing techniques.
• Programming proficiency in JavaScript, TypeScript, Java, Python or a comparable automation language.
• Experience with Git, CI/CD pipelines, SQL, data validation, debugging and Agile collaboration.
• Strong test design, exploratory testing, defect management, documentation and mentoring capabilities.

Preferred expertise and benefits

• Experience in fintech or other transaction-heavy platforms, including reconciliation, idempotency and failure-recovery testing, is preferred.
• Exposure to performance tools such as k6 or JMeter, OWASP-aligned checks and mobile testing tools including Android Studio, ADB or Xcode is an advantage.
• Accessibility testing, device clouds, service virtualisation, test mocking and containerised test environments are valued.
• Competitive salary and benefits, a flexible hybrid schedule and a dedicated learning and certification budget are offered.
