• Build and maintain comprehensive test automation suites across backend APIs, frontend components, and agent workflows
• Design integration tests that validate multi-service interactions and agent orchestration patterns
• Implement end-to-end test scenarios covering data ingestion, transformation, and agent decision pipelines
• Develop automated regression testing frameworks to ensure platform reliability and reduce manual QA overhead
• Create testing infrastructure for agent evaluation, including output validation and performance benchmarking

• Build backend services and APIs using Python to support agent runtimes and data pipelines
• Develop frontend interfaces for agent monitoring, workflow visualization, and human-in-the-loop approval systems
• Implement RESTful and event-driven APIs that connect agent systems to enterprise data sources
• Write clean, maintainable code following team conventions and code review feedback

• Build tooling and utilities that accelerate agent development and debugging workflows
• Contribute to agent evaluation frameworks and observability dashboards
• Participate in agent workflow design and implementation under senior engineer mentorship
