You will join as an AI Engineer specializing in Large Language Models and generative AI. Your responsibilities will include:
- Designing, developing, and deploying production-grade LLM applications leveraging various models and context optimization techniques
- Architecting and implementing sophisticated multi-step and multi-agent workflows using frameworks like LangChain and LangGraph
- Building and optimizing RAG (Retrieval Augmented Generation) pipelines, including embeddings, vector databases, and advanced rerankers
- Leading LLM fine-tuning efforts (LoRA, QLoRA) for domain-specific knowledge and tasks
- Developing and refining advanced prompt engineering techniques to maximize model performance, consistency, and safety
- Owning end-to-end implementation from frontend to backend, including React UI development and REST API integration
- Exposing AI/LLM functionality written in Python through Java services, leveraging multi-threading capabilities
- Utilizing AI-powered development tools (GitHub Copilot, Cursor, etc.) for efficient code generation, refactoring, and optimization
- Collaborating closely with team leads, managers, QA, product managers, and the US-based team (requires willingness to overlap with US working hours)
The role offers high ownership and autonomy, the opportunity to build products end-to-end using AI-first workflows, and the chance to work at the cutting edge of AI-driven software development with multiple leading-edge technologies in a fast-moving, execution-focused culture.
REQUIREMENTS:
- Undergraduate degree in Computer Science or similar Engineering field (advanced degree is a plus)
- 5+ years of professional software development experience, with a minimum of 2 years focused on AI/ML development, particularly with LLMs
- Strong proficiency in Python and relevant data science libraries (Pandas, NumPy, Scikit-learn)
- Proven experience integrating and working with major LLM APIs (Gemini, OpenAI, Anthropic, Llama, Ollama, etc.), including hands-on experience with LLM efficiency techniques
- At least 1 year of deep practical experience with LangChain and LangGraph for building complex LLM applications and agentic workflows
- Practical experience using AI coding tools (Claude Code, Cursor, OpenAI, Microsoft Copilot) and ability to safely integrate AI-generated code into production
- Solid understanding and implementation experience with RAG architectures, vector databases, vector search, embeddings, and reranking mechanisms
- Experience leveraging AI Copilot or similar generative AI coding tools for accelerated development and vibe coding
- Experience creating UI using React and integrating with backend via REST APIs (big plus)
- Hands-on experience with Java, especially integrating Java modules with Python modules (nice to have, not necessary)
- Strong collaboration skills, excellent communication with onshore and offshore teams
- Self-motivated, proactive, strong problem-solver comfortable with ambiguity
- Builder mindset focused on shipping real, working products
- Comfortable with ownership, accountability, and high expectations
- Industry and market knowledge of ESG and sustainability (ideally)
