About the company
MongoDB is building a world-class team in India to create tooling that helps customers verify their application and data modernizations. As companies modernize their application and data ecosystems, ensuring functional equivalence and performance is paramount. The tools developed by the Modernization Testing and Verification team are critical in this journey, helping customers with automated testing, functional equivalence, and performance validation by creating frameworks for contract testing, database state-based testing, and leveraging LLMs for unit test generation.
Responsibilities
- Contribute high-quality, well-tested code to the modernization and framework team and its surrounding services
- Collaborate effectively with Product Management, other engineers, and designers to build and deliver on the product roadmap
- Participate actively in code reviews to enforce best practices and patterns
- Help troubleshoot and resolve complex technical issues in our distributed systems
- Give and solicit feedback on technical design documents and pull requests
- Perform tasks related to process such as CI/CD, quality, testing, etc.
Requirements
- 4+ years of commercial software development experience with at least one JVM language such as Java, preferably using the Spring ecosystem
- Proven experience evaluating Large Language Models (OpenAI, Anthropic, open-weights, etc.)
- Familiarity with evaluation frameworks (DeepEval, Ragas, Promptfoo) and LLM-as-a-judge concepts
- Experience integrating Large Language Models (LLMs) into the developer workflow to automate unit test generation and edge-case discovery
- Experience curating "golden datasets," adversarial test sets, and establishing scoring rubrics to test LLM accuracy, safety, and relevance
- Experience building developer tools, infrastructure, or complex testing frameworks
- Solid experience in software architecture and development
- Experience in application/database modernization with proven ability to design and implement frameworks that ensure database state equivalence across different implementations.
