As a vibrant, international IT scale-up, we support accountants, businesses, and entrepreneurs in handling their accounting more efficiently, simply, and enjoyably. Driven, enthusiastic, and with a quirky side: there's always some buzz in our trendy office in Berchem. And that's the way we like it! At Yuki, we continuously encourage innovation, self-development, and initiative.
Dedicated - Involved, helpful, and full of passion: as one close-knit team, we always go the extra mile.
Well, enough about us: it's high time to talk about your role in our organization! As our AI Product Engineer , you build the AI-driven features our accountants and entrepreneurs actually use. It is our newest role, so you'll sit close to Product and Design, thinking like a mini product manager about where AI can add real value, then building it. Engineer it for production : Own APIs, serving, runtime performance, and latency, and be first response when quality regresses in production.
Land it in the product : NET backend integration, and the front end where it makes sense, alongside our product teams.




Strong software engineering background (min 5 years) building and running commercial software that customers pay for, ideally in B2B SaaS.
You've built with AI, not just around it : LLM APIs, agent frameworks, tool use, orchestration - in something that ran in production, not only in a notebook.
Python and C# (.NET), solid API design, and you're comfortable working across the stack, front end included.
Fluent English is a must.
This is a software engineering role with AI at the centre of it. If your background is data science or data engineering, this is probably not the one for you.
Very Important: What's in It for You
Hybrid working options and gliding hours to suit your lifestyle.
Annual training budgets and access to professional development.
Offices in Antwerp, Barcelona, and Porto, with team-building activities, social events, and inspiring spaces to collaborate.
