Permanent position at Twoday | Copenhagen

AI Engineer – LLMs and On-Premise AI

Do you have hands-on experience building reliable LLM solutions and deploying models in controlled environments? We are looking for an AI Engineer to join Twoday and work on an important digital solution for a Danish public-sector organisation in Aarhus.

Your role

You will work across the development and operation of LLM-based solutions, with a particular focus on models running on-premise. You will help turn AI concepts into secure, stable and production-ready services.

Your responsibilities will include:

  • Developing and integrating LLM-based applications and agents
  • Deploying and operating LLM models in on-premise environments
  • Building RAG solutions, structured workflows and validation layers
  • Improving model reliability through guardrails, testing and monitoring
  • Integrating AI services with existing applications and APIs
  • Working with sensitive data and high requirements for security and traceability

What we are looking for

  • Practical experience developing production-ready LLM solutions
  • Strong Python skills and experience with relevant LLM frameworks
  • Experience with RAG, prompt design, tool calling and structured outputs
  • Knowledge of local or self-hosted models and inference infrastructure
  • Experience with Docker, Linux, APIs and CI/CD
  • A pragmatic approach to hallucination reduction, validation and monitoring
  • Fluent Danish and English, both spoken and written
  • Ability to work full time onsite in Aarhus

Experience with model fine-tuning, GPU infrastructure, NLP or regulated environments is an advantage.

What we offer

You will be permanently employed by Twoday and become part of a strong professional environment within AI and software engineering. Your first assignment will be based onsite with our customer in Aarhus, where you will work closely with both technical specialists and business stakeholders.

At Twoday, you will have the opportunity to develop your expertise, share knowledge with experienced colleagues and help create responsible AI solutions that make a real difference.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
