Role Overview

As an L2 Data Scientist, you will play a hands-on role in delivering production-grade ML and GenAI-powered applications. You are expected to independently take ownership of data science components within client projects, contribute to solutioning and design, and mentor junior team members. You will work across a range of use cases such as personalization, fraud detection, intelligent automation, RAG pipelines, and LLM-based assistants. This role is ideal for someone who has proven experience in both traditional ML and an emerging understanding of LLMs and generative AI applications.

Key Responsibilities

• ML & Data Science Own and deliver ML model development, tuning, and evaluation for client-facing projects.
• Lead exploratory data analysis, data preprocessing, and feature engineering with minimal supervision.
• Build models using appropriate ML techniques (classification, regression, clustering, recommendation) and ensure performance meets business expectations.
• Contribute to experimentation frameworks and model reproducibility best practices.
• GenAI & LLM Applications Design and prototype GenAI solutions using LLMs (e.g., OpenAI, Claude, Mistral, Llama).
• Hands-on experience with AgenticAI.
• Build RAG pipelines, prompt templates, few-shot learning prompts, and evaluation mechanisms for GenAI systems.
• Integrate LLMs with APIs, vector databases (e.g., Pinecone, FAISS, Weaviate), and context providers.
• Contribute to benchmarking, safety, and cost-performance trade-offs in LLM app development.
• Product & Engineering Collaboration Collaborate with engineering teams to take models from experimentation to deployment (batch/real-time).
• Assist in building APIs and data pipelines needed for productionizing models.
• Contribute to technical documentation, explainability reports, and client presentations.
• Team & Growth Mentor junior data scientists and review code/model design.
• Stay current with advances in ML and GenAI to inform solution design and share knowledge internally.
• Participate in discovery and solutioning phases with clients alongside tech leads and PMs.
• Required Skills & Qualifications Bachelor's or Master's degree in Computer Science, Data Science, Engineering, Statistics, or a related field.
• 2 - 5 years of hands-on experience in applied data science, including both ML model development and GenAI-based solutioning.
• Strong command over Python and ML libraries (scikit-learn, XGBoost, LightGBM, etc.).
• Experience working with LLM APIs (OpenAI, Cohere, Claude, etc.) and frameworks (LangChain, LlamaIndex, or similar).
• Hands-on experience with prompt engineering, RAG workflows, and evaluating LLM outputs.
• Proficiency in SQL and data wrangling tools (pandas, NumPy).
• Experience working with REST APIs, Git, and cloud environments (AWS/GCP).
• Good-to-Have Skills Experience with deploying models via FastAPI, Docker, or serverless platforms.
• Knowledge of MLOps tools (MLflow, DVC) and monitoring frameworks.
• Experience with embeddings, vector databases, and similarity search.
• What You Can Expect at CoffeeBeans Work on real-world AI/ML problems across verticals.
• Be part of a fast-moving team delivering end-to-end ML & GenAI apps.
• Collaborate with experienced engineers and PMs in a flat and open culture.
• Opportunities to lead, mentor, and influence tech direction.
