Gammastack - Python Developer - Artificial Intelligence/Machine Learning

 Design and develop AI/ML and AI-powered applications using Python, with FastAPI as the primary framework (Django and Flask also used)

- Build and optimize RAG (Retrieval-Augmented Generation) pipelines using LLMs, embeddings, and vector databases

- Design and execute evaluation frameworks for single-agent and multi-agent systems to measure task completion, reasoning quality, tool usage, and workflow efficiency.

- Develop GenAI solutions using LangChain, LangGraph, LlamaIndex

- Build AI agents and multi-agent workflows for business process automation

- Implement prompt engineering, retrieval evaluation, and hallucination reduction techniques

- Design and enforce LLM guardrails and governance frameworks (content filtering, output validation, safety policies, compliance, and audit logging)

- Build REST APIs and microservices to integrate AI/ML components with backend systems

- Deploy AI/ML services using AWS or GCP services, Docker, Kubernetes, and CI/CD pipelines

- Work with cloud AI platforms : AWS Bedrock, GCP Vertex AI, Azure OpenAI, or OpenAI APIs

- Monitor AI/ML model performance, cost, latency, and accuracy in production environments
