Full Stack Engineer

Overview

AgentShop is building the AI visibility and content intelligence platform for e-commerce. We help brands understand how they appear across AI search engines (ChatGPT, Perplexity, Google AI Overviews) and automatically generate high-converting content at scale. Our platform processes AI citation data, runs automated web scrapers, orchestrates multi-step LLM content pipelines, and integrates natively with Shopify, WooCommerce, and Wix.

We're looking for a Senior AI Full Stack Engineer to own features end-to-end — from interactive dashboards to backend services that orchestrate AI agents, scrape search engines, and power data pipelines.

- Build and maintain web scraping infrastructure that extracts structured data from AI search engines

- Own e-commerce platform integrations (Shopify, WooCommerce, Wix) and build new ones

- Design data models and APIs across PostgreSQL, background job queues, and caching layers

- Collaborate with product and design to scope features and ship quickly

- Improve observability, reliability, and performance across the platform

- Strong React and Next.js proficiency

- Solid Node.js and Express backend experience

- Hands-on experience integrating and orchestrating LLM APIs (OpenAI, Anthropic, Google)

- PostgreSQL data modeling and query optimization (we use Prisma)

- Experience with authentication and payment systems

- Comfort with Tailwind CSS and modern component libraries

- Background in async job processing and workflow orchestration

- Web scraping with headless browsers

Nice-to-Have

- Shopify App development or e-commerce platform experience
