Job description

Yuki & The Yuki Way

Hi there, welcome to Yuki! As a vibrant, international IT scale‑up, we support accountants, businesses, and entrepreneurs in handling their accounting more efficiently, simply, and enjoyably. And to make that possible? Well, we’re looking for kick‑ass colleagues to complete our ambitious, cheerful, and lively team of top professionals!

Come on, now: that sounds like something for you, right?!

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 Engineer, your mission is to take AI models into the Yuki product and build the capabilities users actually touch. You get predictions and GenAI features to land robustly, performantly, and reliably in front of our accountants and entrepreneurs.

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.

• Build GenAI capabilities: Ship compound AI systems, retrieval‑augmented features, and in‑product prompt orchestration.
• Productionize models: Own serving, APIs, runtime performance, and latency so AI lands reliably in the live app.
• Serve retrieval: Build in‑product vector search and retrieval integration, and be first response for model‑quality regressions in production.
• Land it in the product: Integrate AI predictions into the .NET backend alongside our backend engineers.
• Co‑create with Product: Spot new use cases, help shape the roadmap, and build features (including MCP‑based capabilities) with Product and Design.

Job Requirements

• Strong AI software engineering background (min 3 years), with real experience putting ML/AI into production at scale.
• Hands‑on with the stack: Python, Databricks, vector databases, MLflow (serving and monitoring side), and solid API design.
• Comfortable with GenAI application patterns: RAG, agents, and orchestration (experience with an AI agent framework is a big plus)
• A product‑minded builder: you think about use cases, not just tickets, and can co‑create with Product and Design.
• Nice to have: C# (.NET), MLOps tooling, and experience building MCP for a tool or platform.
• Fluent English is a must.

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.
