The Application Modernization Platform (AMP) team is dedicated to solving one of the industry's biggest challenges: transforming rigid, legacy applications that suffer from poor scalability and high operating costs into modern, microservices-based architectures on MongoDB. To accelerate this transition, MongoDB is building a dedicated Platform and Infrastructure team to develop the Application Modernisation Platform and Infrastructure . As we help customers modernize their application and data ecosystems, we face the challenge of deploying complex tooling into highly restrictive client environments and architecting automated verification frameworks to ensure data equivalence.
This new team will architect the platform foundation and infrastructure that enables a "build once, run anywhere" model, ensuring our AI-powered modernisation suite operates seamlessly regardless of a client's security or network constraints. We are looking for engineers to join this high-visibility initiative, where you will solve unique distributed systems puzzles and help shape the future of how global enterprises leverage data and AI.
We are looking for an experienced Software Engineer who thrives on solving infrastructure constraints and building developer-centric modernisation platforms with a strong background in building software testkits/frameworks. The ideal candidate will be designing and building automated frameworks that validate functional equivalence, performance benchmarks, and data integrity. From leveraging LLMs for unit test generation to building contract testing frameworks, your work will be the safety net for the world’s largest enterprise migrations.
This role will be based in our India office in Gurgaon and offers a hybrid working model.
3-4 years of commercial software development experience with at least one JVM language such as Java,



preferably using the Spring ecosystem

- Expertise integrating Large Language Models (LLMs) into the developer workflow to automate unit test generation and edge-case discovery
- Experience building developer tools, infrastructure, or complex testing frameworks
- Solid experience in software architecture and development
- Deep expertise in application/database modernization with proven ability to design and implement frameworks that ensure database state equivalence across different implementations
- Must understand change data capture, event-driven database interception (MongoDB listeners, RDBMS triggers), and state comparison algorithms with pattern-based exclusions. Strong Spring Boot (or equivalent Java framework), MongoDB (or equivalent), and JDBC/JPA skills required
