Software Engineer III

Position Summary...As a Software Engineer III — E2E Quality Engineering at Walmart, you will design, build, and maintain end-to-end test automation frameworks and quality engineering infrastructure that underpin the reliability of Walmart's retail and eCommerce platforms. Working within the Walmart Business Tech team in Chennai, you will partner with product engineering, DevOps, and release teams to embed quality throughout the software delivery lifecycle — from unit coverage and API contract validation to full browser-based E2E flows and performance benchmarks across production-scale environments.

What you'll do...

About Team

 This is the team which builds reusable technologies that aid in acquiring customers, onboarding and empowering merchants besides ensuring a seamless experience for both these stakeholders. They also optimize tariffs and assortment, adhering to the Walmart philosophy - Everyday Low Cost. In addition to ushering in affordability, they also create personalized experiences for customers the omnichannel way, across all channels - in-store, on the mobile app and websites. Our team is responsible for design, development, and operations of large-scale consumer facing applications. We focus on real-time transactions, user experience flows, streaming analytics across web and native apps. We interact with multiple teams across the company to provide scalable robust technical solutions. 

What You'll Do

• Design, develop, and maintain scalable E2E test automation frameworks using Playwright, Selenium, and/or Cypress for web and API layers of retail and eCommerce applications.
• Build and own API test suites covering REST endpoints and Kafka event contracts, validating data integrity, schema compliance, and service-level behaviours.
• Integrate automated test suites into CI/CD pipelines (GitHub Actions, Jenkins) to enforce quality gates on every build, PR, and release candidate.
• Develop performance and load test scenarios (JMeter, Gatling, or k6) to validate system behaviour under production-scale traffic on GCP and Azure.
• Collaborate with software engineers and product managers to understand acceptance criteria and translate them into precise, maintainable test cases.
• Implement test data management strategies — synthetic data generation, environment isolation, and teardown — to support reliable, repeatable test execution.
• Monitor test results, analyse failure patterns, and triage flaky tests; drive root cause resolution with engineering teams.
• Maintain quality dashboards and reporting (test pass rates, coverage trends, MTTR for test failures) visible to engineering and product leadership.
• Contribute to shift-left quality practices — reviewing design documents for testability, pairing with developers during feature development, and promoting TDD/BDD adoption.
• Deploy and operate test infrastructure on Kubernetes / GCP / Azure, including containerised test execution environments and parallel test runner orchestration.
• Champion observability in test pipelines — integrate logging, tracing, and alerting to surface failures rapidly and with full context.
• Leverage AI-powered test generation tooling to accelerate test authoring, improve coverage, and maintain self-healing test suites.
• Collaborate with ML and data teams to validate AI/ML-powered product features — testing model outputs, recommendation accuracy, and intelligent search quality.
• Evaluate and adopt AI-driven quality tools (autonomous test agents, LLM-based defect triage, predictive test selection) to improve engineering efficiency.

What You'll Bring

• 3–5 years of hands-on software engineering experience with a strong focus on test automation and quality engineering.
• Proven proficiency with at least one major E2E automation framework — Playwright, Selenium WebDriver, or Cypress — including page object models, fixtures, and parallel execution.
• Solid experience with API testing tools and frameworks (REST Assured, Postman/Newman, or equivalent) for functional and contract-level validation.
• Strong Java skills for backend test automation — TestNG, JUnit, Maven/Gradle, and integration with CI/CD tooling.
• Proficient in JavaScript and/or TypeScript for front-end and Playwright/Cypress-based automation.
• Experience writing SQL queries and validating data in both relational (PostgreSQL, MySQL) and NoSQL (Redis, Cassandra) stores.
• Working knowledge of Kafka — ability to produce/consume test events and validate event-driven service behaviour.
• Experience integrating automated tests into CI/CD pipelines; familiarity with GitHub Actions or Jenkins.
• Understanding of containerised environments (Docker, Kubernetes) for scalable test execution on GCP or Azure.
• Strong analytical skills — ability to triage complex failures, isolate root causes, and communicate findings clearly to engineering and product stakeholders.
• Familiarity with AI-assisted development and test tooling in day-to-day quality engineering practice.

Preferred Qualifications

• Experience with BDD frameworks (Cucumber, Behave) and collaboration with product owners on feature definition and acceptance criteria.
• Hands-on performance testing experience using JMeter, Gatling, or k6 at production-scale traffic volumes.
• Exposure to contract testing frameworks (Pact or Spring Cloud Contract) for service-to-service validation in microservices environments.
• Experience with accessibility testing (axe-core, Lighthouse) and ensuring WCAG compliance in eCommerce UI flows.
• Familiarity with observability tooling (Splunk, Grafana, Jaeger) for test failure triage and system-level diagnosis.
• Experience testing eCommerce or retail platforms — checkout, cart, product catalog, search, health/wellness verticals.
• Exposure to AI-powered test generation, self-healing selectors, or LLM-assisted defect triage tools.
• Contributions to open-source test automation projects or internal testing libraries.
• Cloud certification (GCP Associate / Azure Developer).
