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
