About The Position

We are a small engineering team inside Natuvion that finds and builds the next high-value additions to Natuvion's product portfolio. We prototype AI-powered solutions for enterprise data transformations — from an idea observed in a customer project to working software. Our work has three focus areas: Content corpus (making Natuvion's transformation knowledge searchable, structured, and available to AI agents), Embedded prototyping (observing customer transformation projects to identify and accelerate processes with AI and technical solutions), and AI and agentic coding practices (establishing how Natuvion applies AI in its products and engineering). We build on top of the Natuvion Cloud Platform (NCP), using its APIs and shared components. The team has strong technical and scientific backgrounds and cares about quality even in prototypes. We are part of Natuvion (~500 employees, SAP Gold Partner), which provides access to enterprise customers, real transformation projects, and corporate backing with the autonomy of a small team. Joining us means working on real problems, not toy projects, involving millions of records, complex business rules, and tight timelines for enterprise data transformations. We offer end-to-end ownership, deciding what to build and how, from observation to shipping a working prototype. AI is a daily tool, not a buzzword, as we use agentic coding and AI-assisted development as core working methods, shaping how the organization adopts these practices. It's a small team with big reach, having direct access to enterprise customers like BMW, Volkswagen, E.ON, and Lufthansa, a cloud platform to build on, and the freedom to move fast.
