Senior AI Engineer – RAG, Open Source LLMs & Kubernetes
Permanent position at Twoday | Consultant role with a public sector client

Do you want to build AI solutions that move beyond prototypes — and into real production systems used by thousands of users?

At Twoday, we are looking for a hands-on AI Engineer to develop and operate AI-powered assistants and chatbot solutions for a large public sector organisation.

This role focuses on practical implementation, integration and operational AI engineering in a modern open-source AI stack.

The technical environment is based on:

• Open-source LLMs

• RAG pipelines

• Kubernetes

• EU-based cloud and hosting providers

• Modern observability and DevOps practices

You will help build AI solutions that are scalable, maintainable and production-ready.

Your responsibilities

You will:

• Build and maintain RAG pipelines

• Work with embeddings, chunking, ranking and retrieval

• Develop AI-powered assistants and chat interfaces

• Integrate AI services with APIs and existing systems

• Deploy and operate AI applications on Kubernetes

• Work with observability, logging and monitoring

• Help document and hand over solutions to operations and internal teams

We are looking for someone who has experience with

• Open-source models such as Mistral, Llama or Qwen

• Python and FastAPI (or similar)

• Kubernetes at application level (deployments, manifests, Helm)

• Docker and cloud-native workflows

• API integration and asynchronous processing

• Logging, monitoring and troubleshooting in production systems

• Ability to work onsite in Copenhagen as required. Currently, for this particular client, you can work from remote Wednesdays only, and are required to work onsite the rest of the time

And also:

• Fluent Danish and English, written and spoken

• Strong hands-on development capabilities

• Ability to work independently in a fast-moving environment

It is an advantage if you also have experience with

• vLLM or similar model serving technologies

• Qdrant, OpenSearch, Elasticsearch or similar vector/search platforms

• Keycloak or OIDC integrations

• EU-based hosting providers (Hetzner, Scaleway, OVHcloud)

• CI/CD and Infrastructure as Code

• GDPR, NIS2 and AI governance requirements

About you

• You are pragmatic and delivery-focused

• You enjoy building real systems used by real users

• You understand how to operationalise AI reliably

• You work in a structured way and document your work

• You are comfortable working close to infrastructure, APIs and production systems

What you get at Twoday

• The opportunity to work with modern open-source AI technologies in production

• Real societal impact through public digital solutions

• A strong engineering environment with experienced specialists

• High technical ownership and influence

• Collaboration with platform engineers, architects and AI specialists

If you want to build production-grade AI systems that matter in practice, we would very much like to hear from you.
