Eucloid - Lead Data Scientist - Vision & Multimodal AI

Overview

We are looking for a Lead Data Scientist Vision & Multimodal AI to architect and build next-generation Vision-Language Model (VLM) systems at scale.

This Role Requires Deep Expertise In

• Architecting and implementing RLHF (Reinforcement Learning from Human Feedback) Frameworks.
• Training and fine-tuning Open-Source Vision-Language Models (VLMs).
• Deploying and scaling multimodal models to production serving millions of Responsibilities & Build RLHF Frameworks :
• Design end-to-end RLHF pipelines (SFT - Reward Modeling - PPO/DPO)
• Develop scalable human feedback collection systems
• Implement preference modeling and ranking pipelines
• Optimize reward models for multimodal outputs (image + text)
• Build automated evaluation & Fine-Tune OSS Vision-Language Models :
• Experience working with Qwen-VL, Llama, GPT OSS
• Pretraining / instruction tuning multimodal models
• Parameter-efficient fine-tuning (LoRA, QLoRA)
• Dataset curation & synthetic data generation
• Scaling training on multi-GPU / multi-node clusters
• Optimizing for alignment, hallucination reduction, and Scalable Deployment of VLM Systems :
• Design distributed inference pipelines (GPU-optimized)
• Model serving using vLLM and Triton Inference Server
• Optimize latency, throughput, and cost
• Implement batching, KV caching, quantization, tensor parallelism
• Deploy on Kubernetes-based infrastructure
• Build monitoring for drift, performance, and AI System Design :
• Architect systems combining OCR, vision encoders, LLMs, retrieval
• Implement retrieval-augmented multimodal pipelines
• Design evaluation benchmarks for VQA, grounding, and reasoning
• Ensure model safety and Leadership :
• Lead a team of ML engineers & research scientists
• Define technical roadmap for multimodal AI
• Review model architectures & code quality
• Collaborate with product and infrastructure :
• 6+ years in ML / AI
• 2+ years working with large-scale LLM or VLM systems
• Strong hands-on experience building RLHF pipelines (not just using libraries)
• Deep PyTorch expertise
• Experience training models >7B parameters
• Experience with distributed training (Deep Speed, FSDP)
• Production-grade deployment experience handling 10k+ QPS workloads
• Strong understanding of transformer architectures.
