Senior Software Engineer, Dev

ibex. is looking for a skilled Python Developer with experience in AI/LLMs, Retrieval-Augmented Generation (RAG), and backend systems to join our team. The ideal candidate will have strong programming skills, a solid understanding of modern AI workflows, and the ability to design, implement, and optimize scalable solutions that integrate Large Language Models with knowledge retrieval systems.

RAG & AI Implementation

• Implement and maintain RAG pipelines using custom or established frameworks such as LangChain
• Work with LLM APIs (e.g., Azure OpenAI, Google Gemini) to build AI-driven applications.
• Set up and manage vector databases (Azure AI Search, Google Vector Search, PGVector, Pinecone or Milvus) for document storage and retrieval.
• Develop utilities for document preprocessing, parsing, chunking, and embeddings generation.

Backend Development

• Build REST APIs to expose RAG/LLM workflows to applications and products.
• Write clean, maintainable Python code using frameworks like FastAPI or Flask.
• Ensure scalability and reliability of backend services in production.

Data & Pipelines

• Build scripts for ETL and data ingestion pipelines to feed knowledge bases.
• Work with structured and unstructured data (text, PDFs, web content, databases).
• Monitor and optimize retrieval quality through embedding updates and reranking methods.

• Master or Bachelor degree in computer science or relevant engineering
• 3-5 years of Experience in relevant field
• Strong programming skills in Python 3.x.
• Experience with AI/LLM integration (Azure OpenAI, Google Gemini, or similar).
• Familiarity with RAG frameworks (LangChain, LlamaIndex).
• Experience with vector databases (Azure AI Search, Google Vector Search, PGVector, Pinecone or Milvus).
• Knowledge of API development (FastAPI, Flask, or Django).
• Solid understanding of prompt engineering techniques for optimizing LLM responses.
• Good understanding of data structures, algorithms, and software engineering practices.
• Git, unit testing, and basic CI/CD experience.
