Responsibilities

Design and Develop AI Agents: Architect, build, and deploy robust, multi-step AI agents capable of complex reasoning, tool use, and decision-making using frameworks like LangChain, AutoGen, or CrewAI. Develop and integrate agentic systems—using LLMs, RAG, and tool-use/function-calling frameworks—to automate or accelerate complex tasks for end-users

RAG: Deep, practical experience with the end-to-end RAG lifecycle, from designing chunking and hybrid retrieval strategies for domain-specific data to implementing agentic design patterns

Workflow and Process Design: Translate user needs into robust, autonomous workflows that can reason, plan, and execute actions

Integrate Tools and Data Sources: Equip agents with the ability to interact with external systems by integrating APIs, databases, and other data sources to enable real-world action and information retrieval

Implement Agentic Architectures: Develop and implement advanced agentic patterns such as ReAct (Reasoning and Acting), plan-and-execute, and multi-agent collaboration to solve complex, open-ended problems

Optimize and Evaluate Performance: Establish rigorous metrics to evaluate agent performance, reliability, and efficiency. Continuously iterate on agent design, prompting strategies, and model choice to improve outcomes

LLM Customization: Fine-tune and adapt foundational LLMs to enhance their capabilities for specific agentic tasks and domains. Implement and refine Retrieval-Augmented Generation (RAG) pipelines to provide agents with relevant, up-to-date context. Proven experience building and shipping applications powered by Large Language Models (LLMs)

Collaboration: Work closely with product managers, data scientists, and other engineers to define requirements, identify opportunities for automation, and integrate agentic solutions into our core products and internal workflows

Stay Current: Keep up-to-date with the latest advancements in agentic AI, LLMs, and autonomous systems, and champion the adoption of new techniques and technologies within the team
