Senior Software Development Engineer in Test Our client's mission is to deliver industry-leadingContact Centre capabilitiesthrough cutting-edge technology solutions.Our team is at the forefront of innovation, shaping the future of client interactions in a rapidly evolving landscape. We’re seeking aSenior Software Development Engineer in Test (SDET)to join ourQuality Engineering (QE) teamand drive automation excellence forAI-powered agentic applications. As ahands-on Senior SDET, you’ll focus ondesigning and implementing automation solutionsto ensure the reliability and intelligence of our next-gen systems.

Collaborate in anAgile environmentto tackle complex testing challenges, from prompt engineering to end-to-end validation.Elevate quality, drive innovation, and make a direct impacton client experience. Design and implement tests across all levels (unit, integration, end-to-end), providing expertise on automation procedures, schedules, and risk mitigation.

Lead test strategy execution: Drive development of test specifications, data analysis, and timelines to ensure on-time delivery. Build automated test solutions using tools like Selenium, Cucumber, JMeter, and TestNG to enhance efficiency and coverage. Create data flow diagrams and define boundary conditions to maximize test coverage.

Manage test lifecycle: Oversee test execution, defect tracking, and results storage while adhering to agreed processes.

Support all test activities: Enhance, develop, and execute both manual and automated test scripts, recording and tracking software discrepancies to ensure thorough issue resolution. Partner with stakeholders and developers to ensure comprehensive testing, reliability, and performance. Guide teams on methodologies, coding standards, and best practices through code reviews and test plan design. Ensure test cases and domain expertise are clearly articulated for seamless team execution.

Integrate testing into CI/CD pipelines: Embed tests for functional/non-functional validation, monitor results, and resolve issues with developers.



5+ years of Quality Engineering experience in diverse environments (cloud, distributed, mainframe, APIs, databases), with a proven ability to resolve complex cross-functional issues. ~3–5 years of hands-on automation experience, designing efficient test strategies to reduce manual testing and covering component, integration, and end-to-end scenarios. ~ Expertise in testing Agentic applications using LLMs and prompt engineering techniques. ~ DevOps proficiency in CI/CD, GitHub Actions, ALM, JIRA, and qTest. ~ Programming skills in Python, Java, C#, SQL, Groovy, PowerShell, and source control tools (Git). ~ Experience in Agile/Iterative Waterfall, defining test strategies, and reviewing artifacts (code, automation scripts). ~ Knowledge of Service Virtualization (RIT, Wiremock), test data management, and non-SQL databases (MongoDB, PostgreSQL).
