The company is looking to solve business problems using data science and machine learning techniques, specifically building and optimizing classification, regression, and forecasting models.
Requirements
- Hands-on experience with Python, and libraries/frameworks such as scikit-learn, pandas, PyTorch, TensorFlow, Hugging Face Transformers, and LangChain.
- Strong understanding of classification metrics, feature engineering, model validation, and hyperparameter tuning.
- Demonstrated experience with LLMs, including fine-tuning, prompt engineering, and retrieval-augmented generation techniques.
- Experience with deep learning architectures including LSTMs, transformers, and other sequence-based models.
- Experience with NLP pipelines for text classification, semantic search, summarization, and question answering.
- Experience with vector databases (e.g., FAISS, Pinecone, Weaviate) and document indexing frameworks.
- Experience with multi-agent AI systems using frameworks like LangGraph, CrewAI, or OpenAgents.
Responsibilities
- Build and optimize classification, regression, and forecasting models using classical ML and deep learning techniques.
- Develop and deploy deep learning architectures including LSTMs, transformers, and other sequence-based models for time-series, NLP, and anomaly detection.
- Design and implement NLP pipelines for text classification, semantic search, summarization, and question answering using transformer-based models (e.g., BERT, T5, GPT).
- Create RAG (retrieval-augmented generation) pipelines integrating LLMs with vector databases (e.g., FAISS, Pinecone, Weaviate) and document indexing frameworks.
- Apply and fine-tune LLMs (e.g., OpenAI, Mistral, LLaMA, Cohere) for domain-specific tasks using supervised fine-tuning or LoRA/QLoRA methods.
- Build and orchestrate multi-agent AI systems using frameworks like LangGraph, CrewAI, or OpenAgents to support tool-using, autonomous agents for decision-making workflows.
- Collaborate with data engineers, product managers, and stakeholders to translate business needs into production-ready solutions.
Other
- 5+ years of experience in data science or applied machine learning.
- Mentor and support junior data scientists through code reviews, model design feedback, and collaborative experimentation.
- Promote best practices in reproducible modeling, responsible AI, and scalable deployment.
- Collaborate with data engineers, product managers, and stakeholders to translate business needs into production-ready solutions.
- Strong background in both classical and deep learning methods.
