We're partnered with an AI company that cleans up and enriches messy product data (PDFs, spreadsheets, images, CAD files) turning it into clean, marketplace-ready catalogs for brands and retailers selling on Shopify, Amazon, Walmart, and large PIM/ERP systems. We're helping the company bring on a few more engineers – one of the positions is this Data Scientist one.

Stack: Python / FastAPI on the backend, React on the frontend, LLMs throughout.

Engagement: Full-time, fully remote.

What you'll do

  • Build React interfaces for large datasets — tables, forms, bulk editing, validation workflows
  • Build UIs that make data work feel fast, not painful
  • Integrate with backend APIs and real-time data flows
  • Optimize for scale — virtualization, pagination, caching
  • Contribute to FastAPI endpoints when it speeds things up

We're looking for

  • 3–7+ years in frontend or full stack
  • Strong React and TypeScript
  • You've built data-heavy UIs before (not marketing sites)
  • Good grip on API integration and state management
  • Comfortable in a Python backend when needed
  • Expert in using AI for coding (Claude Code)
  • Comfortable working with a significant daily overlap with US Pacific Time

Nice to have

  • Virtualization / windowing for huge tables
  • UI/UX taste for enterprise / internal tools
  • Data viz libraries
  • Exposure to AI-driven interfaces
