Core Responsibilities

Primary Functions

Design, implement and maintain test automation frameworks, tools and libraries for functional, regression, integration and end‑to‑end test scenarios.
Collaborate with software developers, QA engineers, product owners and operations teams to understand requirements, define test cases, acceptance criteria and automate test flows accordingly.
Develop and maintain automated test scripts using programming languages such as Java, Python or JavaScript and using frameworks like Selenium, Cypress, Appium, TestNG, JUnit or Robot Framework.
Integrate automated tests into continuous integration / continuous deployment (CI/CD) pipelines (Jenkins, GitLab CI, Bamboo, Azure DevOps) to enable test execution on each build, provide fast feedback and support release gating.
Analyse automated test outcomes, detect, report and track defects, flakiness or coverage gaps, and partner with development teams to debug failures and ensure stable test suites.
Continuously monitor, maintain and improve automation coverage, remove duplicate or obsolete scripts, refactor automation code and adapt the automation suite to evolving application architecture.
Define test automation strategy: select tools, frameworks, libraries and architecture; establish guidelines, coding standards and best practices for automation in the organization.
Perform test environment provisioning, configuration and management, including building virtual machines, containers or test‑installs, ensuring the automation runs reliably across all environments (dev, staging, production).
Create and maintain documentation: automation frameworks, test data, scripts, test results, run‑books, training materials and reporting dashboards to support the QA and development teams.
Identify and implement performance test automation (load, stress, endurance) where required, analyse system behaviour under test and integrate performance testing into overall QA strategy.
Ensure automation solutions support web, mobile (iOS/Android) applications, backend services and APIs, with coverage across multiple platforms and device types.
Maintain version control of automated test artefacts, support branching/merging strategies, collaborate on code reviews, enforce quality and reuse in test code.
Mentor and support more junior automation testers or QA engineers: review test code, share best practices, help uplift the team’s automation capability.
Participate in agile ceremonies (sprint planning, daily stand‑ups, retrospectives), contribute to backlog refinement, estimate automation tasks and align with team deliverables.
Collaborate with DevOps teams to deploy test infrastructure, schedule automated test runs, configure reporting alerts and incorporate test results into release dashboards.
Apply security, compliance and accessibility considerations into automation: test for vulnerabilities, ensure data privacy and integrate security checks into automation pipelines.
Provide input on software design and architecture from a testing perspective: propose how features can be built for testability, observe modularity and test automation readiness.
Analyse metrics (test coverage, execution time, pass/fail rates, flakiness, defect escape rate) and produce reports to stakeholders on automation health and quality trends.
Drive innovation in test automation by exploring new tools and frameworks (AI/ML‑driven testing, container orchestration, cloud‑based testing services) to improve automation efficiency.
Ensure test automation supports application migrations, upgrades and releases: refactor or rebuild automation for new modules, platforms or versions ensuring continuity of test coverage.

Secondary Functions

Support ad‑hoc testing or proof‑of‑concept automation tasks, assist QA teams with manual test case conversion or rapid automation for urgent release cycles.
Contribute to the organisation’s automation roadmap by recommending reusable frameworks, shared libraries, and standardisation across projects.
Collaborate with business units to translate feature requests or bug triages into automation work‑items and backlog entries.
Participate in continuous improvement of QA, automation processes, test data management, environment provisioning and deployment orchestration.
