About Floot

Floot is building the AI-first software foundation for non-coders to build and deploy full-stack web apps. We grew from 5 to 600+ paying customers during YC! 🚀

Unlike other platforms that cobble together dev tools, we're rebuilding the entire software stack for a world where AI writes most of the code.

Our goal: Make Floot the default choice for anyone to build and ship software.

Our founders are staff engineers from Retool and AWS. Edward (CTO) bootstrapped his last SaaS company to $5M+ ARR in one year.

About the role
Skills: Node.js, React, TypeScript

As engineer #1, you will work directly with the founders to build the product and shape our culture. You’ll wear many hats and touch everything from AI systems, user-facing features, to backend infrastructure.

What you’ll do

  • Talk to users often to deeply understand how to improve Floot's AI and UX (you can expect to spend 10-20% of your time on support)
  • Ship full-stack features and build the foundational building blocks that users will use to build their apps seamlessly (e.g. storage, payments, auth, etc)
  • Improve our AI runtime to handle edge cases and make our agentic system more reliable
  • Prompt engineering and evals to improve AI output quality (for both function + design)
  • Build robust infrastructure for our end-to-end platform to power millions of production apps

Requirements

  • Strong full-stack experience with React, TypeScript, and Node.js: you've shipped production features end-to-end
  • Strong sense of ownership: you’re autonomous and own features from start to finish
  • Fast but thoughtful: you ship quickly without cutting corners on things that matter
  • Strong sense for UX and product polish: you believe that craft matters
Technology

Floot is an all-in-one platform with the entire tech stack built-in (backend, database, hosting, etc).

Our stack:

  • Node.js
  • TypeScript
  • React

Deployment:

  • AWS (Lambda, Cloudfront, S3, etc)
  • Neon databases

What we've built:

  • Custom AI-first coding framework
  • Custom sandbox for AI-generated code
  • Custom runtime that runs in frontend and backend
  • Custom deployment infrastructure
  • Multi-model agentic system with advanced debugging capabilities

We're optimizing every layer of the stack for AI.
