Responsibilities

• You design and operate a "5-minute onboarding" workflow with Docker and DevContainers to ensure that "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 use AI to analyze logs 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.

Profile

• You have very good knowledge of Docker, GitHub Actions/Jenkins, and Makefile/CMake environments.
• You have 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.
