About the role

AI-powered forecasting & replenishment for grocery. Join Guac to build AI-native tools and web/mobile interfaces that forecast product sales and enable retailers to optimize inventory, pricing, and replenishment.

Responsibilities

  • Frontend & Product: Own customer-facing features end-to-end on our web application using React/React Native, Next.js, and TypeScript — from shaping the spec to shipping and iterating
  • Implement robust state management and real-time synchronization patterns to ensure data consistency across multiple users and sessions
  • Optimize application performance for handling large datasets and complex user workflows without compromising responsiveness
  • Build AI-native interfaces — natural-language interactions, agentic workflows, and copilots that sit on top of our forecasting and ordering products
  • Backend: 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
  • Expose our data and systems to LLMs via MCP servers, tool-use APIs, and similar protocols
  • Collaborate directly with customers' technical teams to understand and integrate with their IT infrastructure

Qualifications

  • 3+ years of relevant software engineering experience
  • Strong proficiency in Python, TypeScript, and associated frameworks
  • Experience building modern web applications with React and the surrounding ecosystem
  • Strong product sense — you have opinions about UX, you've shipped features that users actually loved, and you can tell the difference between a feature that's done and one that's just deployed
  • 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
  • Comfortable operating with ambiguity and minimal process — you thrive when given a problem and trusted to figure out the solution
  • (Bonus) Experience in customer-facing technical roles (e.g. forward deployed engineer)
  • (Bonus) React Native or mobile development experience

Required:PythonTypeScriptReactNext.js

Benefits

  • Fully employer-paid healthcare (medical, dental, and vision)
