Job Description

Join NCS as a Senior LLM / Multimodal AI Engineer and spearhead the development of next-generation foundation models and multimodal understanding systems. With 4+ years of hands-on experience, you will architect, train, evaluate, and deploy large-scale Vision-Language Models (VLMs) and Large Language Models (LLMs) that process billions of user-generated content (UGC) and advertising videos. You will transform cutting-edge research into industrial-scale recommendation and advertising systems that deliver measurable business impact.

What will you do?

Data Curation & Multimodal Pre-Training

• Architect and scale automated data pipelines that integrate video frames, images, OCR, ASR, and text for VLM pre-training and fine-tuning
• Drive LLM-assisted annotation workflows and synthetic data generation strategies to minimise manual labeling overhead
• Engineer robust data quality frameworks ensuring representative, accurate, and complete training datasets

Model Training & Fine-Tuning

• Reproduce and optimise foundation model series (e.g., LLaVA, Qwen-VL family) for production environments
• Execute supervised fine-tuning (SFT) and post-training for domain-specific content ecosystems including gaming, movies, automotive, and commercial advertising
• Implement advanced training techniques including PEFT, LoRA, and quantization-aware training

Multimodal RAG & Knowledge Bases

• Design and deploy hierarchical Retrieval-Augmented Generation (RAG) pipelines that enrich video understanding and enable in-context retrieval
• Build scalable vector search indexes (e.g., FAISS) supporting billions of embeddings
• Optimise retrieval strategies including hybrid search, re-ranking, and query expansion

Inference Optimization & Deployment

• Optimise large-scale VLM and LLM serving using vLLM, TensorRT-LLM, Triton, and ONNX Runtime
• Implement dynamic batching, feature caching, and asynchronous scheduling to maximise GPU throughput
• Monitor and tune production inference systems for latency, cost, and quality trade-offs

Evaluation & Agent Workflows

• Establish comprehensive online/offline evaluation benchmarks measuring generative quality, aesthetic completeness, and vertical task precision/recall
• Contribute to intelligent tag platform agents and agentic workflow orchestration
• Conduct continuous LLM-as-Judge evaluation on production traces

Qualifications

An Ideal Candidate Should Possess:

Experience

• 4+ years of hands-on experience in machine learning system development, with demonstrated focus on NLP, Computer Vision, LLMs, or Multimodal AI
• Proven track record of independently driving end-to-end ML initiatives from research exploration to high-throughput production deployment

Core Technical Skills

• Deep expertise in deep learning fundamentals, transformer architectures, and multimodal fusion techniques
• Proficiency in deep learning frameworks: PyTorch, Hugging Face ecosystem, DeepSpeed, PEFT, LlamaFactory
• Strong programming capabilities in Python, SQL, Spark, and Linux/Git workflows
• Hands-on experience with vector search and retrieval infrastructure (FAISS, Multimodal RAG)
• Familiarity with LLM/VLM serving and quantization toolkits (vLLM, TensorRT-LLM, Triton)

Preferred Qualifications

• Industrial experience in large-scale recommender systems, advertising technology, or content moderation/understanding ecosystems
• Hands-on expertise with reinforcement learning from human feedback (RLHF) or preference optimization (e.g., DPO, GRPO)
• Published research or competitive achievements in top AI/ML venues or challenges (e.g., CVPR, NeurIPS, ICLR, Kaggle)
• Experience with cloud ML platforms (AWS SageMaker, Azure ML, Google Vertex AI)
• Knowledge of AI observability tools (Langfuse, Weights & Biases, MLflow)
