About the Role

We are looking for an NLP / LLM Engineer to design, build, and deploy language-driven AI systems into production. You will work on large language models, retrieval-augmented generation (RAG), and NLP pipelines that power real-world products. This role blends applied research with hands-on engineering and production ownership.

Responsibilities

  • Design, fine-tune, and evaluate LLMs for NLP use cases such as search, summarising, classification, and conversational AI.

  • Build and optimize RAG pipelines using vector databases, embeddings, and retrieval strategies.

  • Develop prompt engineering, evaluation, and guardrail frameworks for reliability and safety.

  • Deploy NLP/LLM models into production environments and support ongoing optimization.

  • Collaborate with product, data, and platform teams to translate business needs into ML solutions.

  • Monitor model performance, drift, and quality using robust evaluation metrics.

Qualifications

  • Strong experience in NLP and machine learning, with hands-on work on LLMs.

  • Proficiency in Python and modern ML frameworks (PyTorch, TensorFlow, or similar).

  • Experience with embeddings, vector search, and retrieval systems.

  • Familiarity with LLM fine-tuning techniques (LoRA, adapters, quantization).

  • Experience deploying ML models into production environments.

  • Solid understanding of NLP fundamentals (tokenization, transformers, evaluation metrics).

  • Experience training or fine-tuning proprietary models.

  • Experience building agentic or multi-step LLM applications.

  • Experience with LangChain, LangGraph, or similar orchestration frameworks.

  • Experience with MLOps, CI/CD, and cloud platforms (AWS, GCP, Azure).
