What awaits you?

• You design and operate a "5-minute onboarding" workflow with Docker and DevContainers to ensure "it runs on my machine" becomes a reality for every new colleague.
• You operate the team's local AI infrastructure, including Retrieval-Augmented-Generation (RAG) clusters, Cursor skill libraries, and individual documentation indexing that feeds our LLMs.
• You automate and optimize the highly complex compile and hot-reload cycle between the LibreOffice C++ core and the Node.js/JavaScript frontend.
• You develop "intelligent" pipelines that not only report errors but analyze logs using AI and automatically suggest or directly apply patches for fragile legacy build steps.
• You implement "Continuous Profiling" in the build chain to detect 16ms frame budget violations before code even enters a pull request.

What should you bring?

• You have very good knowledge of Docker, GitHub Actions/Jenkins, and Makefile/CMake environments.
• You bring expertise in Python, Go, or Rust for building high-performance internal automation tools.
• You have solid experience with modern web toolchains (Vite, Webpack, esbuild) and optimizing large JavaScript monorepos.
• You have experience with vector databases or self-hosting LLMs (Ollama/LocalAI), which is a big plus.
• You are the team's "Prompt Architect" for infrastructure, using models like Opus 4.6 Max and specialized DevOps agents to automate operational routine work.
• You have experience in AAA game build engineering, especially with automated pipelines for complex, cross-platform assets and codebases where "build time" and "asset cooking" are key KPIs.

What do we offer you?

• Attractive working conditions: You benefit from a hybrid work model and flexible working hours through trust-based working time.
• Modern working environment: At some locations, a subsidized canteen and various free drinks await you, as well as modern office spaces with very good public transport connections.
• Diverse employee benefits: You receive various employee discounts for activities and products.
• Community and events: Look forward to employee events such as summer and winter parties, as well as workshops.
• Training and development: Numerous further training and development opportunities are available to you.
• Health promotion: Various health offers, such as sports and health courses, support your well-being.
