Do you want to help us redefine how AI powers the future of Business Management software, not as an add-on, but as a core part of how people work, decide and grow?

We’re looking for engineers who:
- Treat AI as central to their craft, not a feature to bolt on later
- Want to build and ship, not debate and document
- Care about whether the thing they built actually worked — not what their title says.

Join us as a Founding Engineer in a brand-new Factorial spinoff

We're building a new startup inside Factorial, starting from scratch, with real backing and a clear target: 0 to 10 million in under a year. It's ambitious, and that's the point.

The focus is on rethinking how companies manage workflows, org charts, policies, and analytics, the operational core of what Factorial does. But this isn't an internal project. It's a spinoff with its own identity, its own pace,



and its own team.

The advantage of doing this inside Factorial? We're not starting cold. We have 15,000+ existing customers, a dedicated GTM team, and the infrastructure to move fast. You'll be joining at day zero, but with a real runway.

In terms of what we're building, the tech matters less than you'd think. We care about your ability to move fast, make good decisions with incomplete information, and build things people actually want to use. That said, strong Ruby on Rails experience on the backend and solid React or TypeScript on the frontend will go a long way.

If you've ever wanted to work in a small, scrappy team with the energy of an early-stage startup but without the typical early-stage uncertainty, this is that opportunity.

Ready to be part of the challenge?
