Job description

Job Purpose: The Senior Software Test Engineer role ensures delivery of high‑quality, reliable, and secure software by leading comprehensive testing across distributed, microservices‑based applications. It involves designing and executing test cases, supporting automation frameworks such as Python and Robot Framework, and integrating testing into CI/CD pipelines to validate functionality, performance, and scalability. The role collaborates with cross‑functional teams to identify, document, and resolve defects, while driving continuous improvement to enhance product stability and accelerate delivery cycles. As per company policy, this role requires presence in the office 4 days per week. Duties: Test Case Development & Execution : Collaborate with senior engineers to develop and execute comprehensive test cases that align with project requirements, ensuring thorough testing of software functionality, performance, and security. Automation Support : Contribute to the development and maintenance of automated test scripts and frameworks. Assist in enhancing test automation coverage for both system-level and front-end applications. Issue Identification & Documentation : Identify, track, and document software defects, functionality issues, and performance problems, working closely with developers to reproduce, debug, and resolve issues. Collaboration & Communication : Work closely with cross-functional teams, including developers, product owners, and senior testers, to ensure alignment on testing goals and priorities. Communicate findings and progress effectively. Test Reporting & Metrics : Contribute to the preparation of test reports and track key testing metrics to assess test coverage, defect resolution, and overall testing progress. Support in Test Planning : Participate in test planning activities, contributing to discussions about scope, approach, and strategy for different types of testing, such as functional, regression, and integration testing. Version Control & Configuration Management : Utilize version control systems (e.g., Git, Subversion) for maintaining test scripts, test cases, and related artifacts. CI/CD Integration : Assist in integrating test scripts into Continuous Integration/Continuous Deployment (CI/CD) pipelines to ensure that automated tests are executed as part of the development process. Manual Testing : Conduct manual testing where required, especially in areas that are difficult to automate or require more exploratory testing to identify edge cases. Collaboration on Automation Strategy : Support senior engineers by contributing ideas and improvements to the automation strategy, tools, and frameworks used in the testing process. Continuous Improvement : Provide feedback on testing processes and practices, suggesting improvements and applying lessons learned from past testing cycles to enhance efficiency and test effectiveness. Skills and Experience: A bachelor’s degree or equivalent in Computer Science, Information Technology, or a related field. 4–7 years of hands‑on experience in testing distributed, microservices‑based applications, including test strategy definition, design, execution, and maintenance. Strong experience with automated testing frameworks, with the ability to design, implement, and maintain automation solutions across service‑level, and end‑to‑end testing (Integration). Proficiency in coding and maintaining automated test suites for backend services and consumer‑facing applications, with a focus on service interactions and failure handling. Solid experience in API testing (RESTful services preferred), including validation of contracts, payloads, error handling, and service dependencies. Hands‑on experience with containerization technologies such as Docker, including building, running, and testing containerized microservices. Working knowledge of container orchestration platforms such as Kubernetes (or similar), including validating deployments, service‑to‑service communication, configuration changes, and scalability behaviour. Experience supporting and validating applications deployed via CI/CD pipelines, with an understanding of how microservices are built, tested, and promoted across environments. Good experience with the Atlassian suite of tools, including Jira, Bitbucket, Confluence, and test management tools such as TestRail, along with version control systems like Git and integration tools such as Jenkins. Familiarity with test automation tools and libraries such as Robot Framework, Python , and other relevant frameworks used for microservices testing. Strong understanding of software development lifecycles, microservices concepts, and test methodologies, with the ability to collaborate effectively across development, DevOps, and testing teams. Demonstrated ability to write clear, detailed test cases and maintain accurate documentation of test results and quality metrics in a fast‑moving, distributed environment.
