Software Test Engineer

Software Test Engineer

As an SDET for Client Experiences at Realtor.com, you are a key contributor to the quality of the mobile interfaces that power our primary consumer and agent interactions. You will be responsible for the reliability, performance, and seamless quality of the essential digital interactions that connect consumers and agents, with a particular focus on critical user journeys.

What You'll Do

Strategic Planning & Quality Execution

• Contribute to quality initiatives for mobile client-side experiences, focusing on user interface correctness, visual consistency, and mobile performance metrics.
• Execute a layered test strategy for your squad, primarily focusing on End-to-End (E2E) and integration testing using modern React Native frameworks.
• Identify quality risks in mobile client flows (e.g., cross-platform/OS compatibility (iOS/Android), form validation, and state management) and translate them into actionable Detox automation scripts.

Technical Contribution (Mobile & React Native UI)

• Drive hands-on testing for client applications, utilizing Appium or Detox for native application automation and validating data integrity through GraphQL queries.
• Advocate for mobile testability, including accessible React Native components, native accessibility identifiers (e.g., accessibilityLabel), data-testid attributes, and clear error-handling states.
• Partner with developers to ensure UI components and client-side logic are validated early in the development lifecycle.

Test Automation & Performance

• Design and maintain robust automation suites using Appium and TypeScript (or JavaScript) to validate complex user workflows.
• Perform API and contract validation for GraphQL schemas to ensure the front-end stays in sync with backend services.
• Integrate automated UI checks into CI/CD pipelines (e.g., CircleCI, GitHub Actions) and assist in triaging failing checks to maintain a healthy build signal.
• Support performance testing of mobile app load times, resource utilization (memory/CPU), and battery consumption.

Collaboration & Learning

• Participate fully in Agile/Scrum processes, ensuring UI quality signals are included in the definition of done.
• Collaborate with Product and Design partners to turn user requirements into reliable automated acceptance tests.
• Share best practices and utilities within your team to help software engineers contribute to the shared Appium/Detox codebase.

What You'll Bring

• 3+ years of experience in software and/or test engineering, with a strong focus on React Native mobile applications and native automation.

• Proven experience implementing test scripts for modern mobile technologies, specifically using Detox, Appium or similar mobile E2E frameworks (e.g., Espresso/XCUITest).

• Hands-on experience testing GraphQL APIs, including writing queries and validating schema-driven responses.

• Proficiency in TypeScript or JavaScript and experience building reusable page objects and test utilities.

• Experience with CI/CD integration and a demonstrated ability to reduce flakiness in mobile UI test suites.

• Familiarity with mobile-native debugging tools (e.g., Xcode, Android Studio, Flipper) and observability platforms to isolate client-side errors.

• Experience with native environment setup (simulators/emulators, device farms) for iOS and Android, and experience with visual regression testing or accessibility (a11y) testing is a plus.

• Interest in exploring and applying AI/Agentic testing methodologies (e.g., LLMs, Claude, Copilot) to enhance test coverage, generate data, or accelerate automation script creation.

• Bachelor's degree in Computer Science or a related field, or equivalent professional experience.
