01—Product Engineer

What you will do

  • Shape web and mobile products from the spec stage and ship them yourself
  • Turn LLMs into product features — prompts, evals and cost included
  • Build the revenue plumbing: payments, subscriptions, analytics
  • Use coding agents like Claude Code and Cursor to ship like a whole team

02—How we work

About Multiful

Multiful is a product studio that works 100% remote and AI-native. We ship vertical AI apps for sharp, specific needs — fast — and grow them into businesses people pay for. You will fit especially well if you have shipped a product with coding agents like Claude Code or Cursor, or if you want to start your own company one day.

100% remote

There is no office. Work from any country, any city. Output, not hours at a desk, is what counts.

AI-native

Spec, code, design, marketing and operations — every step runs with AI. Coding agents such as Claude Code are standard tools. Using AI well is part of the craft.

Async, writing first

Few meetings; decisions live in writing. Time zones do not stop the work.

End-to-end ownership

One person owns an area of a product from first line to revenue, and makes calls without waiting for sign-off.

Shared upside

For early core members we discuss equity participation in what we build together. Terms are agreed individually.

Build like a founder, inside

Each product gets its own team, and you run one like its founder. If you dream of starting a company, this is the fastest way to live through zero-to-revenue next to a serial founder.
