Senior Full-Stack Engineer

Required

• You are a great fit if you have:
• 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.
• System design skills, one of your biggest assets. You know how to design architectures that not only scale in the short term, but can also grow with the company with minimal human supervision.
• Claude Code, Codex, and OpenCode are your best friends. You know how to parallelize instances to make sure we're shipping 24/7, even while you sleep, and you know the ins and outs of each of them at any time.
• When it comes to engineering with your toolkit, you don't care whether it's a pickaxe or a shovel. You know which one to use at any time.
• Excited to work directly with CPG operators and own product outcomes end to end, from understanding the workflow to shipping and operating the systems that improve it.
• Motivated by the chance to join an exceptionally ambitious, high-ownership team that moves quickly, holds a high bar, and is determined to build a company that makes history.
