Senior Backend AI Engineer (7 Years) - Agentic AI, RAG, LLM Fine-Tuning Job Title: Senior Backend AI Engineer (Agentic AI, RAG, LLM Engineering) Experience: 7 years Role Summary We are seeking a Senior Backend AI Engineer with 7 years of experience to design, build, and scale production-ready AI systems. The role has a solid focus on Agentic AI platforms, Retrieval-Augmented Generation (RAG), and full LLM lifecycle ownership including training data preparation, fine-tuning workflows, and deployment/serving on cloud-native infrastructure. Key Responsibilities • Own and build backend platforms for Agentic AI products, including autonomous workflows, orchestration, tool-calling, state and context handling, and safety guardrails. • Design, implement, and optimize Retrieval-Augmented Generation (RAG) systems (chunking, embeddings, vector search, reranking, metadata filtering, freshness, and ranking quality evaluation). • Develop and maintain LLM fine-tuning and training pipelines (dataset curation, preprocessing, labeling strategy, hyperparameter tuning, experiment tracking,



and rollback strategy). • Build scalable inference services for LLM and RAG workloads with high availability, low latency, and strict quality monitoring (hallucination, retrieval precision/recall, tool-call accuracy). • Develop and operationalize AI APIs and microservices in Dockerized environments, including model serving stacks, vector store integration, and asynchronous event-driven processing. • Design and manage Kubernetes deployment topologies, autoscaling policies, and disaster recovery for AI services. • Create and own CI/CD workflows for model and application delivery (training jobs, image builds, infra changes, blue/green or canary releases, and post-deploy verification). • Implement MLOps practices: experiment tracking, model versioning, canary validation, prompt and policy regression tests, observability, and performance benchmarking. • Partner with product, data, and infrastructure team
