• Agentic Workflows: Architect and implement sophisticated, multi-step and multi-agent workflows using frameworks like LangChain and LangGraph.

• Retrieval Augmented Generation (RAG): Build and optimize RAG pipelines, including implementing and managing embeddings, vector databases, and advanced rerankers to enhance response quality and relevance.

• Vibe Coding: Use code generation applications (e.g. Replit, Cursor, Google AI Studio, Git Hub Copilot in Agent mode, etc.) to create full applications (including frontend and backend), generate tests, perform testing and integrate them in the core product without writing any code.

• LLM Fine Tuning: Lead efforts in LLM fine-tuning (e.g., LoRA, QLoRA) for specific domain knowledge and tasks, and implement strategies for and efficiency.

• Prompt Engineering: Develop and refine advanced prompt engineering techniques to maximize model performance, consistency, and safety.

• Full-Stack Development: Own end-to-end implementation from frontend to the backend.

• Java (Plus): Expose AI/LLM functionality written in Python using Java services, leverage multi-threading capabilities in Java to augment AI/LLM functionality developed in Python

• Code Quality & Productivity: Utilize AI-powered development tools (e.g., GitHub Copilot, etc.) to efficiently generate, refactor, and optimize high-quality code.

• Collaboration: Work closely with team leads managers, QA, product managers and team in the US (this will require the willingness to partially work US working hours)

• Practical experience using tools like Claude Code, Cursor, OpenAI, Microsoft Copilot, including the ability to safely integrate AI-generated code into production (validation, CI/CD)

• Solid understanding and implementation experience with RAG architectures, vector DBs, vector search, embeddings, and reranking mechanisms

• Experience leveraging AI Copilot or similar generative AI coding tools for accelerated development, code generation, refactoring, optimization, and vibe coding to create integrated backend and frontend applications

• Experience creating UI using React and integrating the UI with the backend using REST APIs is a big plus

• Hands-on experience with Java, especially integrating Java modules with Python modules is a nice to have, but not necessary

• Strong collaboration across a small team, including great communication with both onshore and offshore departments and translating vague requirements into actionable systems.
