-Troubleshoot, debug, and resolve issues in GenAI-powered code translation pipelines

-Collaborate with dev and client teams to ensure alignment with project goals and deliver high-quality solutions

-Maintain and fine-tune RAG application that supports the migration process, specifically optimizing LLM prompts for pattern recognition

-Build and maintain FastAPI-based microservices that orchestrate the migration workflow

-Implement RAG (Retrieval Augmented Generation) systems using LangChain /Langgraph/LlamaIndex for contextual code understanding

-Design stateful migration workflows using LangGraph/LangChain/LlamaIndex for complex multi-step transformations

-Mandatory work from the office 5 days per week.


Skills

Must have

-Proficiency in Python development (5+ years), with specific expertise in:

-FastAPI for building high-performance REST APIs and WebSocket connections

-Async programming patterns for handling concurrent migration tasks

-Pydantic for robust data validation in migration pipelines

-Experience with vector embeddings and embedding models

-Vector database implementation for semantic search

-Graph database experience for code dependency mapping

-Building agents for code analysis, implementing custom tools for mainframe-specific transformations, creating chains for multi-step code migration

-Orchestrating stateful workflows for complex migration scenarios, managing checkpoints for long-running migrations, implementing conditional routing based on code patterns

-Building knowledge bases from documentation, implementing hybrid search for code pattern matching, creating custom retrievers for language specific contexts

-Implementing similarity search and semantic code retrieval systems

-Graph traversal algorithms for dependency analysis

-Strong problem-solving and debugging skills for identifying translation anomalies and semantic preservation issues

-Excellent communication skills for collaboration with client teams and explaining complex technical translations

Nice to have

-Deep understanding of HLASM instruction sets, macro definitions, and DSECT mappings

-COBOL and PL/I for understanding integrated mainframe systems

-Assembly language debugging and performance optimization

-Mainframe utilities (DFSORT, IEBGENER, IDCAMS)

-Experience with mainframe subsystems: CICS transactions, DB2 stored procedures, JCL batch processing

-Knowledge of z/OS internals, linkage conventions, and program calling standards

-Familiarity with EBCDIC to ASCII conversion, packed decimal (COMP-3) handling

-Experience in front-end development (preferably React) for building migration dashboards and progress monitoring interfaces

-Experience in Java development, particularly Spring Boot, to understand target architecture requirements

-Familiarity with large-scale system migrations and modernization efforts, including phased migration strategies and dual-run validation

-Prior experience working in the banking or financial services industry, understanding core banking concepts, regulatory requirements, and transaction processing
