freshcells systems engineering GmbH is a software service provider based in Düsseldorf with a dynamic team of over 50 creative experts from various fields.

We focus on authenticity, individual talent development and open communication. We build on respect, trust and responsibility. As an innovation-driven company, we invest in new ideas. We know that the best results are achieved as a team. We make mistakes, but we learn from them. We are open and courageous for new ways.

Join us on our exciting journey in what is probably the most important and forward-looking area - software development - as a AI Specialist (m/f/d) in full-time hybrid or remote.

We hire people who want to understand how things work, not just how to wire them together.

You don’t have to know everything. But you should want to know why.

We’re seeking an Applied AI Specialist to join our AI team. This role focuses on applying AI models like LLMs, vision OCR, and generative AI to build practical tools such as chatbots, document search systems, and automations. You’ll work hands-on with technologies like Retrieval-Augmented Generation (RAG) to create a knowledge base AI and integrate AI into our workflows via APIs and web interfaces. Beyond building, you’ll teach and present to diverse groups of developers, data scientists, management, and students making good communication skills a must. The role blends on-premises and cloud environments, requiring familiarity with Docker, Kubernetes (k8s), and CI/CD pipelines. If you’re pragmatic, technical, and ready to prototype MVPs, this is for you.
