About the role

Backend Engineer at Guac, an AI-driven forecasting & replenishment startup for groceries. Build robust backend services, ETL pipelines, and AI-powered tools to enable inventory optimization and forecasting for grocery retailers. In-person role based in NYC with sponsorship for work visa.

Responsibilities

  • Design and build robust backend services that power mission-critical ordering and production planning products
  • Build efficient ETL pipelines to handle billions of rows of data, multiple times per day
  • Build AI-powered tools and agents for internal and customer use — exposing our data and forecasting systems via MCP servers, tool-use APIs, and similar protocols so that LLMs can reason over and act on grocery operations data
  • Collaborate directly with customers' technical teams to understand and integrate with their IT infrastructure
  • Help define how we leverage LLMs across the product surface, from agentic workflows to natural-language interfaces over our forecasts

Qualifications

  • 3+ years of relevant software engineering experience
  • Strong proficiency in Python and associated frameworks (FastAPI or similar)
  • AI-native: you use Claude Code, Cursor, or similar AI coding tools daily and ship significantly faster because of it
  • Hands-on experience building with LLMs — tool use / function calling, RAG, agents, or evals — and familiarity with MCP or similar protocols for connecting models to data and systems
  • Experience designing and operating data-intensive backend systems (ETL, large-scale pipelines, distributed processing)
