Python Developer

Kivvo is Germany's first truly data-sovereign Business AI, built for the Mittelstand and hosted in Germany. We are looking for a Python Developer who wants to actively build AI rather than just wait for it to be finished. You will join a team that prioritizes substance over promises, with existing infrastructure, a first pilot customer, and a solid technical foundation already in place. Join us before Kivvo grows larger.

Tasks (Aufgaben)

• Contribute to Kivvo: Build features, data flows, and AI-driven application logic.
• Prepare and process data to enable meaningful AI operation.
• Experiment with and implement solutions using LLMs and Retrieval-Augmented Generation (RAG) concepts.
• Solve problems pragmatically, sometimes with custom code, sometimes with existing tools.
• Participate in team decisions and contribute your own ideas.

Learning Opportunities (Was du lernst)

• How to make AI applications productive – moving beyond prototypes to truly usable solutions.
• How a small team brings a software product from idea to customer.
• Practical experience with Python, LLM APIs, data processing, retrieval systems, and vector databases.
• How to manage uncertainty in a structured and independent manner.

Qualifications (Was wir voraussetzen)

• Python: Proven experience developing tools, scripts, or automations independently (beyond academic learning).
• LLM Experience: Demonstrated experience implementing small applications with LLMs (APIs, automations, tools).
• Proof of Work: Completed personal projects that you can showcase or describe in detail.
• Independence: Ability to learn new topics autonomously.
• Language: Proficient German for the work context and solid English for team, technical discussions, and documentation.

Bonus Qualifications (Nicht erforderlich, aber gerne gesehen)

• Experience with RAG / data-driven AI, including custom applications that search or integrate data.
• Practical experience with vector databases or retrieval systems (e.g., Qdrant, Weaviate, ChromaDB).
• GitHub projects or a portfolio demonstrating your work.
• Experience building structured data pipelines.

Benefits (Was dich erwartet)

• Direct contribution to a product that is going live – not a concept, but real application.
• Backed by an established corporate group with its own IT infrastructure, server environment, and a pilot customer with over 250 employees.
• Full data sovereignty as an architectural principle: Work on truly secure AI.
• Access to Claude Pro and active AI utilization in daily work.
• Small team, short communication lines, no ticketing system: Direct exchange with the founders.
• Hybrid work model: Office located in Mülheim an der Ruhr / Dortmund, with flexible remote options upon agreement.
• Competitive compensation based on experience.

We look forward to receiving your application!
