Job Summary
In this role, you will develop transpiler components to translate legacy code into modern Java applications, create pipelines, perform testing, and diagnose issues in the transpilation process.
Job Technologies
Your role in the team
- Design and extend transpiler/compiler components (ANTLR4 grammars, lexers, parsers, AST/IR models) that translate legacy Natural source code into modern Java (Spring Boot) applications, ensuring generated output is correct, idiomatic, and enterprise-architecture compliant.
- Develop and maintain the translation pipeline in Java: AST-to-IR mappers, IR-to-Java lowering passes, code generators (Spring services, repositories, DTOs), and REST APIs that expose transpilation as a service.
- Define and validate translation correctness by writing unit and integration tests against representative source fixtures and verifying that generated Java code compiles and behaves as expected.
- Diagnose and fix defects surfaced during transpilation (e.g., malformed generated code, incorrect type or naming mappings) by tracing root causes through the pipeline.
- Support build, integration, and operational readiness for the transpiler service: Maven build health, CI pipeline stability, source-control integration, and troubleshooting for downstream teams consuming generated projects.
