‍

We are looking for a talented AI Engineer to join our AI development team. As part of our core AI team, you will play a key role in building and optimizing AI agents, web crawling pipelines, prompt engineering systems, caching strategies, and the data infrastructure that powers our conversational AI platform. You will work on designing and developing scalable AI agents using the OpenAI Agents SDK, implementing sophisticated web scraping systems to build knowledge bases, optimizing Redis caching for real-time performance, querying massive datasets with AWS Athena/SQL, and building RAG systems that enable our AI to deliver accurate, context-aware responses.

‍

The role extends beyond traditional AI development and includes building intelligent web crawlers for content extraction, implementing multi-layer caching strategies for sub-second response times, writing complex SQL queries for analytics and data retrieval, designing agent orchestration systems, implementing RAG (Retrieval Augmented Generation) pipelines, optimizing embeddings and vector search, and prompt engineering at scale. Given our need for real-time, high-quality AI interactions across hundreds of merchants, web scraping reliability, cache hit rates, query performance, response quality, and cost efficiency are critical.
