Kabilio

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.

What We’re Building

Our goal is to become the go-to Financial Operating System for accounting firms and SMEs in Southern Europe, unifying accounting, tax, payments, planning, and banking into a single platform. We are currently a tight-knit team of 65 people and plan to grow in 2026, with a strong focus on engineering, product design, and sales.

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 with Ivan (CTO), Jorge, Karel, Arnau and Lucas, Tech Leads, as well as with a cross-functional team of devs and Product Managers.

You’ll contribute to both 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.

What you’ll do?

Design, build, and maintain full-stack features
