About the Role

We’re looking for a hands-on Software Developer in Test (SDET) to join our growing QA team supporting Connect Plus—Lineage’s next-generation WMS platform. This role will play a key part in shaping and scaling our automation capabilities across UI and API layers, while also contributing to manual testing efforts as we build out our frameworks.

In this role, you'll be embedded directly with our engineering team, working closely with developers to identify defects early, establish testing standards, and contribute to a culture of quality across the stack.

Success in this role means:

- Fewer bugs in production

- A robust test automation foundation that evolves with the platform

- Direct influence on the quality culture of a mission-critical product

What You’ll Do

• Implement and maintain automation frameworks for database and backend testing.
• Create and execute test cases for Stored Procedures, triggers, and database functions to validate business logic and data consistency.
• Implement mocking techniques to simulate database interactions and isolate testing components.
• Develop and maintain unit and integration tests using mocking frameworks such as Mockito, JMock, or WireMock.
• Design, implement, and maintain automation frameworks for UI (React/React Native) and API (Node.js) components.
• Support manual testing as needed, particularly in the early stages of framework maturity.
• Partner with developers to help them create effective unit and integration tests.
• Provide guidance on automation strategy, tooling, and best practices.
• Begin to integrate tests into CI/CD pipelines to enable pre-merge validations.
• Document and troubleshoot bugs; contribute to efforts that reduce production incidents.
• Learn and understand our custom-built WMS platform (Connect Plus), gaining knowledge of how it integrates with other components like WCS, APIs, and data services.

What We’re Looking For

Must-Haves:

• 7+ years of hands-on experience in QA automation across database, SQL, SPROC, web, mobile, and APIs
• Strong experience with frameworks such as JEST, Playwright, Cypress, or Appium
• Skilled in API automation tools (e.g., Postman, RestAssured, or similar)
• Familiarity with React, React Native, and Node.js environments
• Solid SQL skills and understanding of legacy database testing
• Experience with Git and integrating automated tests into CI/CD pipelines

Nice-to-Haves:

• Experience in supply chain or logistics, especially in warehouse automation
• Exposure to performance testing (e.g., JMeter)
• Knowledge of Docker/Kubernetes and test containerization
• Experience with test strategy in early-stage automation environments
