We’re Kabilio, a company backed by two leading venture capital firms, founded by experienced entrepreneurs, Alex Valls and Jose Ojeda, with a strong track record in building and scaling successful tech companies.

Why this role matters?

Today, Kabilio already runs three core products in production — Invoices Processing, Bank Transactions, and Invoicing — used daily by real customers. At the same time, we’re building our Accounting platform, the product that defines our long‑term vision and the reason Kabilio was founded.



AI sits at the core of everything we build, from automating and categorizing financial data to enabling intelligent workflows and decision‑making across the entire financial lifecycle. We rely on modern architectures and proven technologies to turn this vision into a scalable, production‑ready platform.

As a Full Stack Engineer at Kabilio, you will build and own product features end‑to‑end, working closely with Ivan (CTO), Jorge, Karel, Arnau and Lucas, Tech Leads, as well as a cross‑functional team of devs and Product Managers.

You’ll contribute to frontend and backend systems, helping us ship high‑quality software that is used daily by real customers.

This is a hands‑on role focused on delivery, quality, and collaboration, with a high degree of ownership and the opportunity to influence technical decisions without being a people manager.
