A True Yukiaan at Heart

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! We're eager to achieve results, take on our responsibilities, support each other through thick and thin, and continuously focus on an innovative future.

Everything can be improved, and... you can definitely contribute to that!

Values Worth Having

At Yuki, we place our employees first and foremost. Togetherness, authenticity, and collective momentum: that's what we're all about, day in and day out! We consciously choose colleagues who align closely with our core values:

• Entrepreneurial - Dare, do, and persist. At Yuki, we continuously encourage innovation, self-development, and initiative.

• Responsible - We are all essential links within Yuki, and we are aware of our responsibilities.

• Dedicated - Involved, helpful, and full of passion: as one close-knit team, we always go the extra mile.

• Inclusive - We all embrace each other's diversity within an equitable, flat company structure.

Well, enough about us: it's high time to talk about your role in our organization! Let’s go!

Your Role at Yuki

As our AI Product Engineer, you build the AI-driven features our accountants and entrepreneurs actually use. You sit in the Innovation team, where new capabilities start as experiments and the good ones get built into the product properly.

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. If you get excited about agentic AI and want to shape where a product goes, this one’s for you.

• Run experiments that ship: Take an idea for an AI-driven feature from prototype to something running in the live product, and be honest about the ones that should be killed.

• Build agentic capabilities: Work with agent frameworks, tool use, and orchestration to build features that do real work inside Yuki, including MCP-based capabilities.

• 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: Build the feature end to end — the AI part, the .NET backend integration, and the front end where it makes sense, alongside our product teams.

• Co-create with Product: Spot new use cases, help shape the roadmap, and build them with Product and Design.

Job Requirements

• 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.

• Hands-on with the stack: Python and C# (.NET), solid API design, and you’re comfortable working across the stack, front end included.

• A product-minded builder: you think about use cases, not just tickets, and can co-create with Product and Design.

• Nice to have: Databricks, MLflow, vector search, MLOps tooling, and experience building MCP for a tool or platform.

• 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

At Yuki, we believe in empowering our team so they can empower our users. Here’s what we offer:

• Flexibility: Hybrid working options and gliding hours to suit your lifestyle.

• Growth Opportunities: Annual training budgets and access to professional development.

• International Culture: Work in a dynamic, diverse, and inclusive team with colleagues from all over the world.

• Engaging Work Environment: Offices in Antwerp, Barcelona, and Porto, with team-building activities, social events, and inspiring spaces to collaborate.
