Full Job Description

## Accountabilities Architect, design, and develop production-grade LLM applications including copilots, chatbots, and autonomous AI agents. Build and optimize Retrieval-Augmented Generation (RAG) pipelines using structured and unstructured enterprise data sources. Develop agentic workflows with tool calling, function execution, and multi-step reasoning capabilities. Design and maintain backend services and APIs supporting AI inference, orchestration, and system integration. Implement LLMOps/GenAIOps practices including evaluation frameworks, monitoring systems, CI/CD pipelines, and model/version management. Optimize AI systems for performance, ensuring the right balance of latency, cost efficiency, scalability, and reliability. Apply Responsible AI principles and security-by-design practices across all AI system implementations. Collaborate with cross-functional teams including product, engineering, and security to shape AI architecture and strategy. Mentor engineering peers and contribute to establishing best practices in generative AI system design. Requirements: 10+ years of professional software engineering experience with strong backend development expertise. Advanced proficiency in Python, with experience in frameworks such as FastAPI, Django, and modern backend systems. Hands-on expertise in LLM engineering, including prompt engineering, RAG architectures, and APIs such as OpenAI or Amazon Bedrock. Strong experience with Elasticsearch, including vector search, hybrid search (BM25 + embeddings), and semantic retrieval techniques. Proficiency with vector databases such as Pinecone, Qdrant, or ChromaDB and embedding-based retrieval systems. Proven experience building production-grade generative AI systems, including Copilot-style or agent-based applications. Strong understanding of distributed systems, microservices, event-driven architecture, and scalable backend design. Experience with cloud platforms (AWS/GCP), containerization (Docker, Kubernetes), and CI/C
