Founding engineer

Founding Engineer

We're building the most user-friendly, intelligent and AI-native wealth management platform in the Netherlands, where every number traces back to its source. As a founding engineer you'll work directly with our CTO, Paddy Natte, and shape the core product from the ground up.

What you'll work on

• Document extraction and classification at scale: turning messy PDFs, spreadsheets and reports into structured, traceable data
• A knowledge graph across complex ownership structures (holdings, entities, participations, funds)
• A full agent harness: orchestration, routing and validation
• A human-in-the-loop feedback engine that generates labeled training data for models we train on proprietary financial datasets
• Shipping new functionality based on direct customer feedback, fast

What we're looking for

• A cracked builder: someone who moves fast, is intrinsically motivated to deliver their best work, and doesn't think in 9-to-5 terms. No corporate bs. Just building.
• Strong fundamentals in machine learning and/or software engineering, and the taste to know what "good" looks like
• The ability to take ownership of a problem end-to-end, without waiting to be told how

Nice to have

• Experience in finance, wealth management, accounting or financial software
• Experience training or fine-tuning your own models
• Things you've actually built and can show us

Fresh out of university is fine. Raw ability, ownership and taste matter more than years of experience or a specific background.

What we offer

• Real ownership and equity.
• Direct collaboration with our CTO and full access to the best tools to do the work
• Our first customers are also our first investors. Product-market fit has been validated by demand and by the fact that the people using the product are backing the company.
• Extra's: Dinner included, Swapfiets, gym membership

📍 Rotterdam office presence is required. We believe the best work happens when we build in the same room.
