Senior QA Engineer – Onsite – Sandton
Product/Project management
Johannesburg – Gauteng – South Africa
ENVIRONMENT:
A prominent company in mining technology, specializing in advanced analytics and solutions, is looking for an Senior QA Engineer to join their team in Sandton to spearhead their testing strategy, initially focusing on manual testing while progressively designing and implementing an automation framework across their technology stack. The ideal candidate will have hands-on experience setting up multi-tiered testing environments (QA, SIT, UAT) and be comfortable handling complex testing scenarios, including hardware integrations (weighbridge indicators, IoT devices, cameras and NFC scanning). This role requires someone confident in their ability to work independently, establish a QA practice from scratch and eventually build and lead a team.
DUTIES:
Manual Testing & Test Case Development
- Perform end-to-end manual testing for desktop (React + Electron), mobile (React Native + Expo) and web (React) applications.
- Design and execute detailed test cases, test plans and acceptance criteria tailored for various applications and scenarios.
- Ensure test coverage accounts for complex configuration-based workflows across multiple client environments.
Automation Strategy & Implementation
- Develop an automation strategy that aligns with the platform’s needs.
- Implement and maintain automated test frameworks for:
- Web: Playwright, Cypress, Selenium.
- Mobile: Appium, Detox.
- Desktop: Playwright, WinAppDriver, WebDriverIO (or similar).
- Introduce mocking/stubbing strategies for scenarios where full automation isn’t feasible due to hardware dependencies.
Multi-Environment QA Setup (QA, SIT, UAT)
- Establish and maintain structured testing environments (QA, SIT, UAT) that allow for staged deployments and controlled testing.
- Define a release verification process, ensuring all software updates are fully tested before reaching production.
- Collaborate with DevOps to integrate testing into CI/CD pipelines using GitHub Actions, Jenkins, or similar.
Hardware & IoT Integration Testing
- Develop test plans for IoT hardware interactions, including weighbridge indicators, NFC scanning and cameras.
- Design test methodologies that validate real-world performance and accuracy of hardware-software interactions.
- Implement simulation environments or stubs for automated testing when physical hardware isn’t available.
Defect Tracking & Process Improvement
- Identify, log and prioritise bugs and defects in tracking tools such as GitHub.
- Define metrics to evaluate testing efficiency and software quality over time.
- Continuously refine QA processes, introducing best practices from Agile, DevOps and automation-first methodologies.
REQUIREMENTS:
Must-Have Skills & Experience
- Minimum of 5 years’ experience in software testing, covering manual and automation testing.
- Strong experience testing desktop, mobile and web applications.
- Proven ability to implement and scale test automation frameworks for different platforms.
- Proficiency with automation tools such as Playwright, Appium, Selenium etc.
- Hands-on experience with multi-tiered test environments (QA, SIT, UAT) and structured release testing workflows.
- Familiarity with CI/CD pipelines and version control (GitHub, Bitbucket, or similar).
- Ability to stub/mock hardware interactions to enable automation in scenarios where direct integration isn’t feasible.
- Strong understanding of test data management, API testing and performance/security testing basics.
- Excellent analytical and troubleshooting skills, with attention to detail.
Preferred Skills (Nice to Have)
- Experience with hardware-integrated testing (weighbridge indicators, IoT devices, NFC scanning and cameras).
- Experience setting up QA environments from scratch in organisations that previously lacked structured testing.
- Exposure to security testing and performance testing.
