## About the Role

* Solid understanding of software design principles, algorithms, and data structures.
 * Strong debugging and troubleshooting skills, especially reasoning through multi-stage data pipelines.
 * Familiarity with automated testing (JUnit or similar) and quality assurance practices.
 * Understanding of secure software development practices.
 * Ability to work effectively with architects and stakeholders, including reading and reasoning about unfamiliar or legacy source languages.
 * Familiarity with legacy mainframe languages (Natural/Adabas, COBOL, or similar) is a plus but not required.
 * Familiarity with cloud-native/containerized environments.
 * Knowledge of ITIL-based operational processes and production support/monitoring concepts.

Erfahrung

 * Professional experience in Java development; comfortable working in a Spring Boot codebase.
 * Experience with REST APIs and service integration.
 * Experience with Git and collaborative development workflows (branches, PRs, code review).
 * Experience with ANTLR4 (or another parser generator), lexers, parsers, grammars, and Abstract Syntax Trees.
 * Experience building or maintaining source-to-source transpilers, compilers, or static analysis tools.
 * Experience with intermediate representations (IR) and multi-pass lowering/transformation pipelines.
 * Experience with CI/CD pipelines and scripting for build/test automation.

## Description

* 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.
