The Event Data Tooling (EDT) team works on improving the quality of data emitted from Reddit client platforms (iOS, Android, Web) to support the reliability of Reddit Core Metrics. We own the core eventing logic: event processing, enrichment, caching, and emission from the client side. We are actively increasing coverage of our core telemetry by unit, integration, and end-to-end tests. Our customers are product teams building their telemetry using our libraries for analytics.

Additionally, we collaborate with Data Science, Machine Learning, and other data organizations contributing to the data quality of their metrics.

What We’re Working On

• Building/redefining analytics libraries and tooling for high-quality data construction, validation, and emission from Reddit platforms producing over 1.5M events per second
• Supporting data owners with migration from legacy analytics services/libraries to refactored ones
• Increasing the reliability of Reddit core metrics by improving code coverage with unit, integration, and end-to-end automated testing

What We Are Looking For

• 5+ years of experience with Kotlin or Java within Android development
• Willingness to build Android tooling for data construction/emission and refactor legacy codebase
• Familiarity with software engineering best practices such as unit/integration/end-to-end testing, design documents, CI/CD, A/B testing, code reviews, and documentation
• Excellent communication skills to collaborate with stakeholders in engineering, data science, machine learning, and product
• Nice-to-have: experience with Espresso and/or UIAutomator frameworks, writing Big Query/SQL queries

Responsibilities:

• Develop, evolve, and maintain internal android analytics libraries producing over 500k events per second
• Write clean, scalable, well-designed, and well-tested code that adheres to best practices
• Build new and maintain existing unit, integration, and end-to-end automated tests
• Participate in the full Android development cycle: design, develop, QA, experiment, analyze, and deploy.
