AI Engineer

🔥 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 leading AI-native Financial Operating System for accounting firms and SMEs in Southern Europe, unifying accounting, tax, payments, planning, and banking into a single agentic platform. We are currently a team of 70 people and plan to grow in 2027, with a strong focus on engineering, AI, 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 beta testing our first two Agents and finalizing our Accounting & Tax 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.

You will be a foundational part of the AI team! You will work closely with Ivan, the CTO, Guillem, Daniele, Yosleny and Marc, AI Engineers. As well as with a cross-functional team of engineers and Product Managers, to work on AI specific use cases solving real challenges.

What you’ll do?

• You will work in an environment where AI is already integrated across our products.

• collaborate in designing a new platform for AI agents that will take the interaction with our software to the next level, enabling more autonomous and intelligent workflows for users.

• You will work with generative AI systems already running in production, where AI pipelines process thousands of documents every day and generate real operational value for customers.

• Depending on your level of seniority, you will have significant ownership over the AI stack at Kabilio, from architecture decisions to implementation and evolution.

• You will collaborate closely with a strong product and engineering team to build new features and define where AI creates the most value, deciding when to use classical ML approaches versus modern generative AI systems and how to integrate them into the product.

What we offer?
