Senior Machine Learning Engineer (NLP/LLM)

Role: Senior Machine Learning Engineer (NLP/LLM)

Industry: Enterprise AI & Cloud Software — building scalable NLP and Large Language Model (LLM) solutions for search, summarization, conversational AI, and intelligent automation across B2B and consumer platforms. This is a fully remote role based in India helping accelerate production-grade LLM deployments, RAG systems, and real-time inference pipelines.

Orbion Infotech is hiring an experienced ML engineer to lead design, implementation, and operationalization of LLM-driven products that deliver measurable customer impact. You will join a distributed engineering team focused on model quality, inference efficiency, and robust ML platform practices.

Role & Responsibilities

• Design and implement end-to-end LLM/NLP pipelines: data collection, preprocessing, fine-tuning/adapter training, evaluation, and deployment.
• Build and maintain Retrieval-Augmented Generation (RAG) systems: embeddings, vector store integration, FAISS-based search, and relevance tuning.
• Optimize inference throughput and latency: quantization, batching, ONNX/Triton optimizations, containerized deployment (Docker) and autoscaling.
• Integrate LLM capabilities into backend services and APIs using LangChain (or equivalent) and orchestrate workflows for prompt templates, tool calling, and agentic flows.
• Implement monitoring, testing, and CI/CD for ML models: unit/eval tests, drift detection, observability dashboards, and rollout/rollback strategies.
• Partner with product, data engineering, and MLOps teams to define success metrics, mentor engineers, and drive ML best practices across the org.
