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. Paid time off benefits include PTO (including sick leave), parental leave, family care leave, bereavement, jury duty, and voting. Other benefits include short-term and long-term disability, company discounts, Military Leave Pay, adoption and surrogacy expense reimbursement, and more. You will also receive PTO and/or PPTO that can be used for vacation, sick leave, holidays, or other purposes. The amount you receive depends on your job classification and length of employment. It will meet or exceed the requirements of paid sick leave laws, where applicable. For information about PTO, see https://one.walmart.com/notices.
