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.
Full Stack Engineer Overview
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 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.

Contribute to technical discussions and propose improvements to the codebase.
What we offer?
Salary range: Competitive salary (TBD in the first call).
Flexible benefits via Cobee.
Hybrid setup: 3 days/week in our Barcelona office. The home office days give you time to focus and the flexibility to plan your day around your productivity peaks.
Opportunity: Enter a massive market ready for disruption. We have a clear strategy to make our mark in Spain, leveraging what we have seen in other markets.
Collaborative and Growth Culture: We prioritize open communication and respectful discussions. Your ideas will have a real impact, and you will have the chance to shape and grow with the business.
What should you bring to the table?
Ability to work autonomously while collaborating with a team. Technical ownership.
Strong experience building production web applications, ideally with React and Node.js.
Good understanding of relational databases (PostgreSQL or similar).
Experience working across the full product lifecycle (e.g. SaaS).
Care for clean code, maintainability, and best practices.

Above all, you’re a reliable and trustworthy person.
