Software Engineer (Java)

Stack

Responsibilities

• ▹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
