Founding Product Engineer — Stealth Consumer + B2B Startup

Founder-level ownership. Meaningful early equity. No ticket queue.

We're working with a tiny, founder-led startup rebuilding the software layer of a huge, under‑loved industry - one still held together by legacy systems, spreadsheets, and WhatsApp groups. Millions of passionate consumers, thousands of businesses, and barely any software built by people who actually live the product.

The product is already live on the App Store with alpha users, Android alongside it, and early conversations underway with exactly the kind of customers that make the bar real. They're shipping daily across a consumer app and a B2B operating system: live real-time features, GPS, watchOS, booking, payments, workflows, integrations.

What you'll do

  • Build core product across iOS, Android, the B2B platform, backend, and internal AI‑native tooling – whole surfaces, not isolated tasks
  • Ship directly from field insight: customer visits, user feedback, real operational pain
  • Turn vague, messy, high‑context problems into simple decisions and working software
  • Use AI aggressively and intelligently – for engineering, prototyping, QA, and product thinking

Who you are

  • A strong product‑minded engineer who ships across mobile, backend, and web
  • High taste, low ego – you care about speed, feel, and the difference between useful and merely functional
  • Comfortable with ambiguity, allergic to vagueness
  • You move fast without making a mess, and AI is part of how you work, not a novelty

What this is not

Not ticket‑taking. Not maintaining a polished enterprise SaaS machine. Not a big team with clean lanes. Not a role where a PM tells you what to build.

This is a genuine founding seat: you'll shape the company, the product, the architecture, and the culture. Early enough to matter, far enough along that it's not theoretical.

Meaningful early equity. Real ownership. Weird, concrete, exciting work.
