Senior AI Engineer
AI in this role
Stop building AI that never meets production. Build systems that make an impact. Most AI roles stop at tweaking models or working on proof-of-concepts. Yours won’t. At ML6, you develop and implement AI solutions that are actually used by companies such as Scout24, ING, and ntv.
We are currently looking for senior talent to help shape the technical solutions in one of our GenAI domains (Emerging or Customer Experience).
In the Emerging Domain, you will focus on cutting-edge innovation to build what others are only reading about. You will work on topics such as autonomous AI agents, advanced work assistants, and Agentic AI platform engineering.

In the Customer Experience (CX) Domain, your focus will be on redefining the user journey. Your mission is to work on advanced Retrieval-Augmented Generation (RAG) systems and conversational AI.

A free preview built only from this posting: what it asks for, what you could be asked in an interview, and how to adjust your resume.
Skills and AI tools this role asks for
Questions you could be asked
- How would you design a retrieval step so the model answers from real data instead of guessing?
- How do you decide when an AI agent can act on its own versus asking for approval first?
- How do you monitor a model once it's live, and how do you know it needs retraining?
- How would you decide a model or AI system is ready to ship?
- Tell me about a time a model underperformed in production. How did you find out, and what did you change?
Adapt your resume
- List these exact terms on your resume: Rag, AI Agents, and Ml Ops. An applicant tracking system matches the wording, not the idea.
- Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
- Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
