• Maintain robust CI/CD pipelines, regression test coverage, and integration test suites for high-fidelity emulation
• Provide a fast and intuitive local development loop with meaningful error messages, good performance, and easy configuration
• Improve emulator usability in CLI tools, SDKs, and client integrations (e.g., JDBC, SnowSQL, 3rd party integrations)
• Design and implement support for additional data platform features, services, and cloud providers (e.g., Azure Synapse, BigQuery)
• Track cloud service evolution and update emulators to reflect new capabilities or changes
• Build abstractions that make it easy to plug in new service behaviour or data models
• Ensure emulators work seamlessly with orchestration and infrastructure-as-code tools (e.g., dbt, Terraform, Airflow, CDKs)
• Gather and act on feedback from internal and external teams to prioritize high-impact integrations
