Job Description

With over 4 million domains and more than 2 million customers, we, as an IONOS company, are among the largest web hosting providers worldwide. We operate two TÜV-certified data centers with over 70,000 servers. Our products are diverse and form the backbone of our success, but they only come to life through our amazing employees.

You are the architect of developer velocity. Your goal is to eliminate every second of friction in the engineering lifecycle, ensuring that a complex, multi-language (C++/Node.js) project feels as lightweight and responsive as a modern greenfield app. You don’t just manage servers; you manage the "AI-Ops" infrastructure that allows our Specialists and Staff engineers to work at 3x traditional speeds.

Tasks

• Environment Mastery: Design and maintain a "5-minute onboarding" workflow using Docker and DevContainers. You ensure that "it works on my machine" is a guarantee for every new hire.
• AI-Ops & RAG Management: Manage the team’s local AI infrastructure, including Retrieval-Augmented Generation (RAG) clusters, Cursor Skill libraries, and the custom documentation indexing that feeds our LLMs.
• The Bridge Pipeline: Automate and optimize the high-complexity compilation and hot-reload cycle between the LibreOffice C++ core and the Node.js/JavaScript frontend.
• Autonomous CI/CD: Build "intelligent" pipelines that don't just report failures but use AI to analyze logs and automatically suggest (or apply) patches for brittle legacy build steps.
• Performance Guardrails: Implement "Continuous Profiling" in the build chain to catch 16ms frame-budget violations before code ever reaches a pull request.

Qualifications

• Advanced proficiency in Docker, GitHub Actions/Jenkins, and Makefile/CMake environments.
• Expertise in Python, Go, or Rust for building high-performance internal automation tools.
• Strong experience with Modern Web Tooling (Vite, Webpack, esbuild) and optimizing large-scale JS monorepos.
• Familiarity with managing Vector Databases or LLM self-hosting (Ollama/LocalAI) is a significant advantage.
• The AI Factor: You are the team’s "Prompt Architect" for infrastructure. You will use models like Opus 4.6 Max and specialized DevOps agents to automate the "toil" of system administration, focusing your human intelligence on systemic optimizations and creating a seamless "Flow State" for the coding team.
• The Gaming Edge: We highly value experience from AAA Game Build Engineering If you have managed the automated pipeline for complex, multi-platform assets and codebases where "Build Time" and "Asset Cooking" are primary KPIs, you have the exact DNA we need for this high-performance office suite.

Benefits

• Hybrid working model.
• Flexible working hours through trust-based working hours.
• At some locations a subsidized canteen and various free drinks.
• Modern office space with very good transport connections.
• Various employee discounts for activities and products.
• Employee events such as summer and winter parties, as well as workshops.
• Numerous training and development opportunities.
• Various health offers, such as sports and health courses.

We value diversity and welcome all applications - regardless of, for example, gender, nationality, ethnic or social origin, religion, disability, age as well as sexual orientation and identity, physical characteristics, marital status or any other irrelevant factor subject to applicable law.
