🔥 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 35 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 Tech Lead at Kabilio, you will play a key role in shaping how we build and scale our product. You’ll work closely with working closely with with Ivan, CTO, Jorge, Karel and Arnau, Tech Leads, as well as with a cross-functional team of devs and Product and a small, high-impact engineering team, combining hands-on development with technical leadership, architectural decision-making, and mentoring.

This is not a pure management role: you will write code, set the technical direction for your area, and help the team ship high-quality software at speed.

What you’ll do?

• Take technical ownership of core parts of the platform.

• Lead design and architectural decisions in collaboration with the CTO.

• Be accountable for the technical quality and long-term maintainability of your area.

• Write high-quality, maintainable code across the stack, with a strong focus on system design and critical backend components.

• Guide and mentor engineers through code reviews, pairing, and technical discussions.

• Balance technical quality with pragmatic trade-offs to deliver iteratively.

• Improve engineering practices around testing, performance, and reliability.

• Collaborate closely with Product and Design to shape solutions.

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.

• Indefinite Spanish Contract + top work equipment

• 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?

• 5+ years of experience building production-grade software. Ideally, experience with React and Node.js (not a deal breaker).

• 1 or 2+ years acting as a Tech Lead or senior engineer with leadership responsibilities.

• Solid understanding of relational databases (PostgreSQL or similar).

• Experience making architectural decisions in real-world systems.

• Comfort working in a fast-moving startup environment.

• Professional level Spanish, and English (B1 should be enough).

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