Qué esperamos de ti

• Experiencia mínima de 5 años en Desarrollo SW con Python.
• Conocimientos sobre arquitecturas de software.
• Diseño técnico de soluciones.
• Experiencia trabajando en entornos complejos con múltiples tecnologías y niveles de madurez.

Project Description:

We have an ambitious goal to migrate a legacy system written in HLASM (High-Level Assembler) from the mainframe to a cloud-based Java environment for one of the largest banks in the USA.

Responsibilities:

We are looking for an experienced Senior Python Developer who can help perform the migration of the client platform:

• 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

Mandatory Skills:

• Experience in front-end development (preferably React) for building migration dashboards and progress monitoring interfaces (2+ years)

• 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 Skills:

• 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 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

• Knowledge of performance tuning and optimization in cloud environments, including auto-scaling strategies and cost optimization
