We are seeking a highly skilled Data Scientist with deep expertise in modern AI/ML systems, including LLMs, multimodal models, fine-tuning techniques, and advanced retrieval architectures. In this role, you will design, prototype, and deploy AI-powered solutions that leverage state-of-the-art language, vision, and agentic frameworks. You will work closely with engineering, product, and research professionals across the US and Europe to bring cutting-edge AI capabilities into production environments. Your Responsibilities: - Design, build, and optimize LLM-powered systems using OpenAI, Anthropic, and open-source/local model families. - Architect and implement RAG pipelines, including hybrid search, query rewriting, prompt optimization, and reranking strategies. - Develop and maintain vector database infrastructures (Pinecone, Weaviate, Qdrant) for large-scale embedding storage and fast retrieval. - Train, evaluate, and retrain embedding models for domain-specific semantic search and knowledge retrieval. - Build and integrate multimodal AI solutions using OCR, CLIP, and modern vision architectures for text-image understanding. - Apply fine-tuning techniques (LoRA/QLoRA) to adapt foundation models to organizational datasets and specialized tasks. - Develop production-ready AI applications using Python, PyTorch, and modern orchestration frameworks. - Implement LLM orchestration with LangChain or LlamaIndex, including evaluators, tool abstractions, memory, and RAG components. - Establish robust evaluation frameworks to measure model performance, reduce hallucination, and ensure reliability in production. - Build agentic workflows using AutoGen, CrewAI, or similar frameworks to power automation and multi-agent collaboration systems. - Stay current with research trends and apply theoretical and practical insights in Generative AI to drive innovation across the organization. What we look for: - Experience in applied machine learning or data science, with at least 2 years focused specifically on LLMs or Generative AI. - Demonstrated experience building end-to-end RAG, fine-tuning, or multimodal AI systems. - Strong proficiency in Python, PyTorch, and AI tooling ecosystems. - Experience deploying models at scale in production environments. - Strong understanding of evaluation metrics, model reliability, and safety/reduction of hallucination. - Familiarity with vector embeddings, vector databases, and semantic search. - Experience with agent frameworks such as AutoGen, CrewAI, or LangGraph-like toolkits. - Experience with distributed training, model optimization, quantization, or GPU acceleration. - Knowledge of DevOps/MLOps tooling for deploying LLM-based systems. - Contributions to open-source LLM or RAG projects. What we offer: - Competitive salary and performance-based bonuses. - Fully remote, flexible work environment. - Modern laptop and hardware provided by us. - Specialized training in AI, automation, and digital productivity tools. - Global exposure—collaborate with top-tier founders and fast-growing startups. - Continuous learning and career growth opportunities in an international environment.
