Job description

Über IONOS Bei IONOS verwalten wir nicht nur Server, wir prägen mit unseren Lösungen die digitale Zukunft für über 6,2 Millionen Kundinnen und Kunden weltweit. Als Europas führender Hosting-Anbieter und Pionier für unabhängige Cloud-Lösungen bauen wir eine Infrastruktur der nächsten Generation: von souveränen Cloud-Architekturen und hochperformanten GPU-Clustern bis hin zu integrierten KI-Automatisierungstools. Was uns antreibt: Digitale Entscheidungsfreiheit für Europa und echter Impact für kleine und mittlere Unternehmen (KMU) sowie Großunternehmen. Wir arbeiten in agilen Teams, setzen auf transparente Strukturen und glauben daran, dass Exzellenz und Innovation nur mit echtem Teamgeist entstehen. Bereit für Deinen nächsten Schritt? Werde ein Teil von IONOS und wachse mit uns. About the team: Our mission is to build a modern ecosystem used for all IONOS customer support needs. The tools developed by us are used in over 20 locations, by more than 2.000 users, supporting 8 million customer contracts in 10 markets. The development team has full responsibility for the development lifecycle. This means we plan, develop, test and deploy our software without any other internal or external dependencies. Our portfolio revolves around an internally built CRM which is now being enhanced with AI capabilities. About the product you will be building: We are building a next-generation AI platform designed to redefine how our company interacts with customers. This isn't just a chatbot; it's a high-performance, multimodal AI ecosystem powered by state-of-the-art Speech-to-Speech (S2S) models, advanced Large Language Models (LLMs), and intelligent orchestration frameworks. Our platform will understand, reason, and respond across text and voice — while seamlessly executing real-time actions to resolve customer needs. We are aiming for a hybrid architecture of Open Source LLMs, industry-leading proprietary models, and Model Context Protocol (MCP) to enable contextual reasoning, tool invocation, and seamless orchestration across systems. The goal is not just to talk to the customer, but to act on their needs. What makes this project unique: The Voice Frontier: We are building low-latency, emotive speech-to-speech pipelines for a truly natural voice channel experience. Deep System Integration: Our platform connects directly to the company's core systems via MCPs, allowing the AI to access real-time customer context and execute complex workflows. Self-Evolving Logic: We are developing an automated QA and evaluation module that continuously analyzes interactions across channels.By programmatically measuring quality, accuracy, latency, and resolution outcomes, we can close the feedback loop, and adapt system behavior in hours, not weeks. Hybrid Innovation: You’ll work at the intersection of "build vs. buy," integrating the best of the open-source community with custom-built internal infrastructure. What's in it for you: You won't just be shipping code; you’ll be part of making this concept evolve and shift. You’ll join a friendly, experienced team where your voice matters and your contribution shapes real-world outcomes. You’ll work in a modern environment with technologies and practices that help us ship reliable software efficiently.
