The role also requires strong analytical thinking, technical judgement, and the ability to collaborate effectively with engineering and product teams in a fast-paced, Agile environment.

Key Responsibilities

1. Test Strategy and Quality Engineering

• Develop and implement comprehensive QA strategies, test plans, and testing frameworks for complex SaaS applications.
• Define testing standards, quality benchmarks, and best practices to ensure product reliability, scalability, and performance.
• Lead quality assurance activities across the software development lifecycle, from requirements analysis through release validation.
• Identify potential quality risks, recommend mitigation strategies, and drive continuous improvement in testing processes.
• Collaborate with engineering and product teams to establish quality objectives and ensure consistent delivery standards.

2. Test Automation and Framework Development

• Design, develop, maintain, and optimise automated test frameworks using tools such as Selenium and JUnit.
• Create and execute automated test suites for web applications, mobile applications, and APIs.
• Identify opportunities to increase test coverage, reduce manual effort, and improve testing efficiency through automation.
• Integrate automated testing into continuous integration and delivery workflows.
• Review test scripts and frameworks to ensure maintainability, reliability, and alignment with engineering best practices.

3. Performance, Load, and Security Testing

• Plan and execute non-functional testing activities, including load, stress, performance, and security testing.
• Use tools such as JMeter to evaluate application performance, responsiveness, and scalability under varying workloads.
• Identify performance bottlenecks, reliability issues, and potential security vulnerabilities.
• Analyse test results, prepare detailed reports, and work with engineering teams to resolve identified issues.
• Validate the behaviour of distributed systems under high traffic and complex operating conditions.

4. Web, Mobile, and API Testing

• Lead testing initiatives for distributed, scalable web and mobile applications.
• Design and execute functional, regression, integration, and end-to- end test scenarios.
