At IONOS, the leading European provider of cloud infrastructure, cloud services and hosting services, you will work together with a wide range of teams. We are characterized by open structures, a friendly working culture and flat hierarchies with a strong team spirit. We firmly believe that work and fun are compatible, and offer you the right environment for this. Our constant growth means that we are always looking for new colleagues. Become part of IONOS and grow with us.
In our Trinity Development & QA department, we focus on one clear mission: making professional website creation and online success accessible to busy SMB owners.
Our goal is to help customers create, manage and grow their online presence without needing deep technical knowledge.
Customer-centricity and design-driven innovation are at the core of everything we do. We constantly challenge ourselves to think from the user’s perspective, simplify complexity and deliver real value, not just features.
You’ll be joining a diverse, international team working across locations, Bucharest and Germany. Collaboration is key for us: designers, testers, developers and product teams work closely together to bring ideas to life. Our colleagues are passionate about their work, eager to experiment with new ideas and AI Tools, technologies and approaches. They thrive in a learning environment, constantly seeking out opportunities to expand their knowledge and skills. You'll find yourself surrounded by a team who embraces challenges, values curiosity and pushes the boundaries of what's possible.
Our AI-powered website builder combines powerful technology with simplicity and is designed with a suite of Do-It-Yourself services to help our customers shine online.
Our product is built on JavaScript technologies, using TypeScript for both front-end and back-end development. We use NodeJS on back-end, React & Redux for the front-end and GraphQL to connect them. All web applications operate on a Kubernetes-like cluster, structured as microservices.
Looking ahead, we are evolving our product beyond a traditional website builder into an AI-driven ecosystem. Our vision is to transform it into an Active Assistant - bridging the gap between user intent and execution.
Our customers will transition from "learning a tool" to "achieving an outcome" through a natural language-first interface, from conversational and visual editor to an intelligent agent that can propose, execute and optimize changes autonomously.
This program is intended for students (currently enrolled in a bachelor's or master's program) who want to gain experience, following what they learned in a specialized faculty, in order to become IT specialists.
As an UX Working Student, your role is to help us design the right solutions and design them the right way, so that our users can easily create and manage their own websites.
We’re looking for someone who is curious, motivated and eager to grow in the UX field, with a strong interest in creating intuitive and meaningful user experiences.

We firmly believe that work and fun are compatible, and offer you the right environment for this. Our constant growth means that we are always looking for new colleagues. Become part of IONOS and grow with us.
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.
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.
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.
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.
As an AI Engineer on this team, you will build the core intelligence systems behind our multimodal AI platform.You will be responsible for moving beyond simple chat interfaces to build high-performance, real-time systems that handle complex reasoning, deep context retrieval, LLM orchestration, retrieval-augmented generation (RAG) and seamless voice interactions.
