Data Scientist / AI Engineer - GenAI & Advanced ML in Mumbai
TapFin is seeking a skilled Data Scientist / AI Engineer with 2-3 years of experience to join our team in Mumbai. This is a fantastic opportunity to build and deploy cutting-edge AI/ML and LLM-driven Generative AI (GenAI) solutions on large-scale datasets.
Role Overview
We are looking for a hands-on professional with practical experience in developing and deploying real-world AI/ML and GenAI solutions, particularly LLM-based applications that have moved beyond the prototype stage and are production-ready. This delivery-focused role will involve working with high-scale data, production ML pipelines, and implementing GenAI-powered features across our analytics and intelligent applications.
Key Responsibilities
- Design, build, and deploy LLM-based and GenAI solutions for production use cases.
- Develop Retrieval-Augmented Generation (RAG) pipelines, LLM workflows, and AI-powered assistants.
- Perform prompt engineering, model evaluation, and fine-tuning workflows.
- Build and optimize advanced ML models for prediction and analytics.
- Work with large-scale structured and unstructured datasets.
- Develop scalable model inference and serving APIs.
- Integrate AI/ML systems with product and data platforms.
- Improve model performance, latency, and cost efficiency.
- Collaborate with engineering and product teams to productionize AI features.
- Continuously monitor and improve deployed AI systems.
Required Skills
- Strong Python programming and ML ecosystem experience.
- Hands-on experience building LLM and Generative AI applications.
- Experience with prompt engineering, RAG architectures, embeddings, and vector search.
- Experience with LLM tooling/frameworks such as LangChain, LlamaIndex, or similar.
- Experience with vector databases like FAISS, Milvus, Pinecone, or equivalent.
- Practical experience with PyTorch or TensorFlow.
- Experience working with large-scale datasets and distributed data processing.
- Experience deploying ML/AI models as APIs or production services.
- Strong SQL and data analysis skills.
- Understanding of ML model lifecycle, evaluation, and monitoring.
- Exposure to MLOps practices and experiment tracking.
- Experience with cloud platforms (AWS / GCP / Azure) is preferred.
- Familiarity with streaming or high-volume telemetry data systems is a plus.
Ideal Profile
- Has successfully shipped at least one LLM/GenAI solution in production or near-production environments.
- Strong problem-solver with a build-first mindset.
- Comfortable working with ambiguity and fast iteration cycles.
- Focused on practical, scalable AI solutions, not just experimental notebooks.
- Clear communicator capable of translating business needs into effective AI solutions.
