We support multi-channel e-com brands with demand planning, replenishment and inventory optimization to avoid stockouts & overstock and improve inventory visibility. Backed by Y Combinator.
About the role
You’ll own features end to end, from data models and APIs to the planning interfaces customers use every day. You’ll design the architecture that turns messy operational data into actions in real time, so physical goods flow reliably to the right place at the right time. You’ll be part of the core team to make the physical flow of goods programmable.
What they're looking for
- Hands-on experience with our stack on both sides of the wire. Python and FastAPI on the backend. Vue 3 (or deep React experience and the willingness to switch), TypeScript, and Tailwind CSS on the frontend. A track record of shipping real products
- A track record of building full-stack apps end-to-end: designing the data architecture, building the API, and shipping the UI that puts it in users' hands
- Experience building data-dense product UIs such as interactive charts, editable tables, and
- drag-and-drop planning tools, and keeping them fast with server-state patterns like TanStack Query
- Proficiency in SQL, writing high-performance queries despite millions of data points for even a single customer
- A habit of testing what you ship: pytest on the backend, Playwright and Vitest on the frontend. Your features work, and stay working
