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) React Native or mobile development experience.

Responsibilities

• 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.
• 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.
