Founded in 2021, Pulsora the “Enterprise Sustainability Platform”, is a well-funded Silicon Valley software startup. It is dedicated to empowering purpose-driven enterprises to manage and improve their environmental, social, and governance (ESG) and overall sustainability footprint with an integrated, comprehensive, flexible, and innovative technology platform built for compliance, tracking, and insight. We are well funded, have amazing customers across industries and geographies, established strategic partnerships with leading ERP and consulting firms, and are growing fast!About the job We are seeking a highly skilled and experienced AI/ML Developer to join our team. The ideal candidate will be a specialist in the rapidly evolving field of Large Language Models (LLMs) and generative AI, with a strong background in developing, integrating, and optimizing complex agentic and RAG-based systems.What you will doLLM Integration & Development : Design, develop, and deploy production-grade applications leveraging various LLMs, context optimization, etc.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, GitHub 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 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 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).About youUndergraduate degree in Computer Science or similar Engineering field, advanced degree is a plus5+ years of professional experience in software development, with a minimum of 2 years focused on AI/ML development, particularly with LLMsStrong proficiency in Python and its relevant data science libraries (e.g., Pandas, NumPy, Scikit-learn)Proven experience integrating and working with major LLM APIs - both public and private/local, e.g., Gemini, OpenAI, Anthropic, Llama, Ollama, etc., including hands-on experience using techniques for LLM efficiencyAt least 1 year of deep practical experience with LangChain and LangGraph for building complex LLM applications and agentic workflows using autonomous agents, tools, memory management, parallelization, etc.Solid understanding and implementation experience with RAG architectures, vector DBs, vector search, embeddings, and reranking mechanismsExperience 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 applicationsExperience creating UI using React and integrating the UI with the backend using REST APIs is a big plusHands-on experience with Java, especially integrating Java modules with Python modules is a nice to have, but not necessaryA little more about how you like to workStrong collaboration across a small team, including great communication with both onshore and offshore departments and translating vague requirements into actionable systems.Self-motivated and proactive—you create momentum without needing directionA strong problem solver who can navigate ambiguityA builder who cares about shipping real, working productsComfortable with ownership, accountability, and high expectationsThrives outside of traditional work structuresYou own the quality of the product you buildWhy this roleHigh ownership and autonomyOpportunity to build products end-to-end using AI-first workflowsWork at the cutting edge of AI-driven software developmentWork with multiple leading-edge technologiesFast-moving, execution-focused cultureBenefitsIdeally have industry and market knowledge of ESG and sustainabilityThe company will pay with salary, equity, and benefitsYou’ll get to work on problems that are hard and importantYou get to work on a solution that helps the planet and helps us allYou’ll be joining an extraordinary team at the beginning of an extraordinary journeyHybrid-friendly work environment, in office 2-3 times per week (for those in New York, San Francisco Bay Area, and Munich)Join us and become a driver for positive change!#J-18808-Ljbffr
