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.

• Use existing LLMs, vision OCR, and generative AI to solve real-world problems in software engineering and for users of web applications.
• Create web chatbots, automations, pagebuilder prompt chatbots, APIs and potentially plugins.
• RAG for knowledge base AI, document search, and programming integrations.
• Develop Minimum Viable Products (MVPs), then scale solutions, build robust architecture and delegate tasks as needed.
• Knowledge transfer AI tool usage and concepts.
• Manage AI solutions in both on-premises and cloud environments.
• Use and create Model Context Protocol (MCP) servers or similar techniques to enhance AI capabilities.
• Understand AI risks and opportunities within software engineering and business.
• Stay up to date on latest models and ways of using AI.

• Strong (Python) programming skills.
• Hands-on experience with RAG, embeddings, and LLM context management.
• Familiarity with LangChain, LlamaIndex, PocketFlow, or similar AI frameworks.
• Knowledge of web technologies and networking basics.
• Proficiency with Docker, Kubernetes (k8s), Git, and CI/CD pipelines (Nix as an alternative is a plus).
• Ability to present complex ideas clearly to technical and non-technical audiences.
• Practical mindset for prototyping and scaling AI solutions.

Nice to have

• Experience with vision OCR, document search, or code integrations.
• Background in on-premises AI deployments and hybrid cloud setups.
• Prior teaching or presentation experience with diverse groups.
• Awareness of AI ethics and governance in software engineering.

All people are welcome here, regardless of gender, age, sexual identity, origin, religion, ideology, with or without a disability. The main thing is that you fit in with us.
