Design and own automated testing for a backend microservices platform: build service-level unit/integration tests, cross-service integration and contract tests, create reusable automation frameworks, integrate tests into CI/CD, troubleshoot flaky tests and distributed system issues, and collaborate with product, security, and infrastructure to improve reliability and developer velocity.
Position Summary...What you'll do...About the Role
We are looking for a driven Software Development Engineer in Test (SDET) to support a backend heavy, microservices based architecture built primarily in TypeScript. This role requires someone who can operate independently and take ownership of automation across both service level and cross service testing. You’ll ensure each service is well tested in isolation while also building robust integration and end-to-end test strategies that validate how services interact across the system. This is a high impact role focused on improving reliability, accelerating development velocity and embedding quality into the engineering culture. About the Team The Vizio Identity team owns the platform level systems that power identity, user data, and trust. Our scope includes authentication and authorization, PII storage and lifecycle management, device linking and management and user consent and privacy controls. We are responsible for how user data is securely stored, accessed and governed across the platform, as well as how identity integrates with internal services and third-party providers. The team partners closely with product, security, legal and infrastructure to ensure our systems are scalable, compliant, and easy for other teams to build on. Our mission is to provide a secure, reliable, and developer-friendly foundation for all user-related functionality—balancing usability, privacy and system integrity. What You’ll Do
• Design and implement automated testing strategies for a distributed microservices
architecture
• Build and maintain service level (unit + integration) automated tests for
TypeScript/Node.js services
• Develop cross-service integration tests to validate APIs, contracts, and workflows
• Create and evolve reusable automation frameworks for backend and API testing
• Integrate tests into CI/CD pipelines to provide fast, reliable feedback
• Collaborate with engineers to embed testing into the development lifecycle
• Identify gaps in coverage and drive improvements in system reliability
• Troubleshoot flaky tests, distributed system issues, and test environment challenges What You Bring
• 7+ years of experience in an automation-focused role (SDET, QA Automation Engineer,
or similar)
• Strong experience testing backend systems and microservices architectures
• Proficiency in TypeScript and experience with Node.js services; experience in C#/.NET is
a plus
• Hands-on experience with automation tools/frameworks (e.g., Jest, Mocha, Playwright,
or similar)
• Experience with API, integration, and contract testing (e.g., Pact or similar)
• Familiarity with CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI, etc.)
• Solid understanding of distributed systems (service dependencies, retries, eventual
consistency)
• Ability to operate independently and take ownership of ambiguous problems At Walmart, we offer competitive pay as well as performance-based bonus awards and other great benefits for a happier mind, body, and wallet. Health benefits include medical, vision and dental coverage. Financial benefits include 401(k), stock purchase and company-paid life insurance.
