Descripción del empleo

We’re looking for a CTO & Co-Founder

Tech brains wanted. Equity included.

Before we dive in, let’s keep it simple :

This isn’t just a job offer.

We’re not looking for an employee.

We’re looking for a third founder. Someone who wants to build, lead, and leave their mark.

That means :

• Real ownership (a meaningful equity stake in OnePool)
• No salary at the beginning (until we regulate MRR or raise funding)
• Full autonomy and a seat at the table from day one

If you’re still reading... this might be for you.

What’s OnePool?

Group payments are broken.

When you book something with friends (travel, events, group experiences) it usually ends like this :

One person pays everything

The rest “send their share” via transfer, Bizum, or other

Someone always forgets, and people get annoyed.

It’s a pain for consumers.

It’s a conversion killer for businesses.

OnePool fixes this by letting everyone in the group pay their part directly at checkout. No manual steps, no friction, no chasing.

What we’ve already done

Built a live MVP

Integrated with major PSPs

Signed our first clients

Joined a top startup accelerator in Spain

The product is real.

The pain is real.

The timing is right.

Now we’re ready to go faster and smarter.

What you’ll do

As CTO and co-founder, you’ll lead everything tech :

Define and drive technical vision

Turn the MVP into a scalable, secure product

Integrate new PSPs, booking engines, vertical tools

Shape the stack and infrastructure

Own the full lifecycle : from roadmap to deployment

Move fast, learn from real users, and iterate with purpose

Tech today : Next.js + Typescript —>

but we’re open to your vision.

Who you are

You’re not just a developer. You’re a builder.

You’ve shipped real products (and made real mistakes)

You think in experiments and MVPs, not perfection

You care about the “why” as much as the “how”

You like autonomy, ownership, and figuring things out

You’ve worked with payments / APIs (or you’re fast at learning)

You want to co-create something big, not just code for someone else

What we offer

Significant founding equity

Full flexibility (remote, async, your stack, your pace)

Role in a future unicorn

An ambitious and down-to-earth founding team

A spot in one of Europe’s top startup ecosystems

If you’ve been waiting for the right project, with the right people and real ownership… this might be it.
