About the Role
We are looking for an experienced Java Backend Developer to contribute to annotation and RLHF initiatives focused on backend systems and server-side logic. In this role, you will review and annotate real-world Java backend code, validate patches, execute and analyze test suites, and identify root causes of failures through structured debugging and reasoning. You will work with production-grade repositories and pull requests, carefully assessing business logic, concurrency, error handling, and system behavior, and providing high-quality human feedback that helps improve the correctness, reliability, and reasoning capabilities of advanced AI models.
Key Responsibilities
- Review, analyze, and annotate Java backend code, patches, and pull requests for RLHF and AI training datasets
- Evaluate server-side logic for correctness, business rules, edge cases, and maintainability
- Execute and interpret Java test suites (JUnit, TestNG, or similar) and annotate test outcomes
- Annotate differences between correct vs incorrect implementations, highlighting bugs, anti-patterns, and risks
- Evaluate code involving APIs, microservices, database interactions, and error handling
- Label code quality aspects such as readability, scalability, reliability, and best-practice adherence
- Ensure annotations are accurate, consistent, and aligned with defined annotation guidelines
- Collaborate asynchronously with AI and data teams to continuously improve dataset quality
Required Skills & Experience
- 15 years of hands-on experience in Java backend development
- Strong understanding of core Java, OOP principles, and backend architecture
- Experience with Spring Boot, REST APIs, or microservices-based systems
- Proficiency with JUnit, TestNG, or other Java testing frameworks
- Ability to debug runtime exceptions, logical errors, and concurrency issues
- Familiarity with Git workflows, code reviews, and large codebases
- Strong analytical and reasoning skills for evaluating correctness and side effects
- Experience with multithreading, concurrency, and backend performance tuning is a plus.
Why join Us
- Work on high-impact projects that contribute to building AI for Good.
- Collaborate with top-tier engineers and domain experts from IITs, NITs, and BITS.
- Opportunity to grow in a fast-paced, innovation-driven environment.
