Your Role at Yuki

As our Applied Data Scientist, your mission is to build the machine-learning models that make Yuki smart — the models that classify documents and predict the right general ledger (grootboek), turning a client's raw invoices into clean, usable accounting data.

This is a modeling role with real production discipline. You won't just train models and walk away; you'll keep them accurate as the data and the business shift. And you won't be heads-down in isolation either. You'll co-create with engineers and product people, and you'll grow a genuine understanding of how accountants actually think about a document.

• Build the models: Train and evaluate classic ML (XGBoost, scikit-learn) and transformer models for document classification and ledger prediction.

• Fine-tune LLMs: Do real model training and fine-tuning with PyTorch and HuggingFace

• Design experiments: Own feature engineering, model evaluation, and selection, plus embedding and retrieval strategy for vector search.

• Guard production quality: Run drift detection, eval pipelines, and the MLflow model registry so models hold up over time.

• Learn the domain: Build deep understanding of accounting and financial-document structure, and translate it back into modeling decisions.
  

Job Requirements

• A strong applied ML background (min 4 years in the field) , comfortable across both classic ML and transformer models.

• Hands-on with the stack: Python, PyTorch, scikit-learn, HuggingFace, Pandas, MLflow, Databricks, Snowflake.

• Rigorous about evaluation, you ship models that survive contact with production, not just the notebook.

• A communicator and co-creator: strong IC who thinks, shares, and explains ML in plain business language (data-driven storytelling and visualization a real plus).

• Nice to have: financial/accounting domain exposure and experience with large document corpora.

• Fluent English is a must.

Very Important: What's in It for You

• Personal development: A generous training budget available from day one for specialised certifications, courses and training to solidify your expertise.

• Time off and flexibility: Plenty vacation days (and the option to buy extra days), plus the possibility of Workation: up to 5 weeks per year of remote work.

• Well-being & focus: Access to lifestyle coaches, well-being programs and other initiatives that contribute to your well-being and focus.

• Financial security: A competitive base salary with attractive benefits.

• Plenty of opportunities : Enjoy the speed and autonomy of an innovative scale-up, backed by the stability, vast resources, and global career network of the Visma Group

• Team & international culture: Participate in (international) team-building days, and other Yuki events that strengthen the close team spirit in a diverse and international environment.
