Over de vacature

At the Mercedes-Benz Customer Assistance Center (CAC), we support customers across the globe. But behind the scenes, we are transforming into a data-first organization. We are looking for a Junior Data Scientist who doesn’t just "do data," but builds intelligent systems.

In this role, you won't just be analyzing the past; you will be building the future of customer interaction using LLMs, RAG architectures, and scalable data pipelines within the Microsoft Azure ecosystem.

what we offer

• €3.607 - €4.122 a month
• Long term commitment
• Personal development
• 40 hours a week
• International and dynamic environment
• Mercedes-Benz CAC, Maastricht

who are you
We are looking for a proactive "self-starter" who thrives in a technical, fast-paced environment.

Your technical and personal toolkit:

• LLM & NLP Expertise: Deep understanding of embeddings, vector search, topic modeling, and RAG architectures. Experience with prompt engineering and orchestration frameworks (e.g., LangChain or LlamaIndex).
• Data Engineering: Proficiency in Azure Databricks, PySpark, and Spark SQL. You know how to ingest data from APIs, streams, and files into well-modeled data layers.
• Software Craftsmanship: Strong Python skills with an emphasis on modularity, Pydantic for data validation, and professional Git workflows.
• Agile Mindset: Comfortable working in an Agile or SAFe environment, taking full ownership of your tasks from conception to deployment.
• Communication: Transparent, proactive, and able to translate "tech-speak" into business value.
• Critical Thinking: You don't just execute; you ask "Why?" to ensure we deliver the best possible solution for the Mercedes-Benz customer.
• Language: Fluent in English (written and spoken).

what will you do
As part of the data science team, you will bridge the gap between advanced AI research and practical, scalable business solutions.

• Architecting Intelligence: You will design and build LLM-based solutions for information extraction, summarization, and conversational AI;
• Engineering Pipelines: You will develop scalable data pipelines in Azure Databricks using PySpark and Spark SQL, ensuring our data layers are optimized and robust;
• Coding Excellence: You write clean, modular Python code. You don’t just build "one-offs"; you build shared libraries and reusable components that make the whole team faster;
• AI-Assisted Development: You embrace the future by using Copilot and other AI assistants to accelerate your workflow while maintaining high standards for validation (Pydantic) and version control (Git/GitHub);
• Proactive Collaboration: You will act as a consultant to the business, explaining complex AI concepts to stakeholders and challenging requirements to ensure we solve the right problems.

where will you work

• Work with the latest Azure Databricks features and cutting-edge LLM frameworks.
• Join a vibrant, multicultural hub in Maastricht with over 35 different nationalities.
• A "Junior" title here doesn't mean "basic." You will have a steep learning curve and the autonomy to take initiative.
• A chance to drive the digital transformation of one of the world’s most iconic premium brands.
