Data Scientist- AI- Remote

Data Scientist (Remote) | 6-10 Years Experience We are actively looking for experienced Data Scientists with strong expertise in Statistical Machine Learning, Deep Learning, and Generative AI for an exciting remote opportunity. Location: Remote Shift Timing: 2nd shift (2PM to 10PM IST) Experience: 6-10 Years Core

Design and ship end-to-end ML solutions spanning structured data, text, and image modalities Apply rigorous statistical thinking — experimental design, A/B testing, causal inference — to validate hypotheses Build and fine-tune LLMs for domain-specific applications including RAG, summarization and classification Develop computer vision pipelines for detection, segmentation, or recognition tasks depending on business need Evaluate, select, and integrate foundation models and open-source checkpoints appropriately Own model performance from training through production — monitoring drift, retraining, and version management Mentor junior data scientists and contribute to internal tooling and best practices Mandatory skill domains — all three are required, no exceptions: 1. Statistical machine learning (mandatory) Strong grounding in probability theory, distributions, and maximum likelihood estimation. Practical experience with gradient boosting (XGBoost, LightGBM), regularised regression, and SVMs. Ability to design statistically sound experiments with appropriate power analysis and significance testing. Familiarity with Bayesian frameworks such as PyMC, Stan, or Pyro for uncertainty quantification. Key areas: Bayesian inference, probabilistic modelling, ensemble methods, causal inference, survival analysis, hypothesis testing. 2. LLMs & generative AI (mandatory) Hands-on experience fine-tuning or adapting open-source LLMs (Llama, Mistral, Falcon, or similar). Ability to design and evaluate retrieval-augmented generation pipelines using vector databases (Pinecone, Weaviate, Chroma, or FAISS). Familiarity with model evaluation frameworks — RAGAS, LangSmith, or custom eval harnesses. Understanding of model quantisation, context window tradeoffs, and inference cost optimisation. Key areas: RAG pipelines, fine-tuning (LoRA / QLoRA), prompt engineering, embeddings & vector search, LLM evaluation, agentic workflows. 3. Computer vision (mandatory) Experience with detection and segmentation frameworks — YOLO variants, Detectron2, SAM, or similar. Proficiency with vision transformer architectures (ViT, DINO, CLIP) and their fine-tuning. Ability to handle real-world CV challenges: class imbalance, domain shift, and limited labelled data. Familiarity with multimodal models such as LLaVA, GPT-4V, or Gemini for vision-language tasks. Key areas: object detection, image segmentation, classification, vision transformers, multimodal models, data augmentation Email -
