About the Role

You are the architect for Developer Velocity. Your goal is to eliminate every second of friction in the engineering lifecycle and ensure that a complex, multilingual project (C++/Node.js) feels as lightweight and responsive as a modern Greenfield app. You don't just manage servers – you are responsible for the "AI-Ops" infrastructure that enables our Specialists and Staff Engineers to work at triple speed.

Responsibilities

  • Environment Mastery: You design and operate a "5-minute onboarding" workflow with Docker and DevContainers. You ensure that "it runs on my machine" is a reality for every new colleague.
  • AI-Ops & RAG Management: You operate the team's local AI infrastructure, including Retrieval-Augmented-Generation (RAG) clusters, Cursor Skill Libraries, and the individual documentation indexing that feeds our LLMs.
  • The Bridge Pipeline: You automate and optimize the highly complex compile and hot-reload cycle between the OnlyOffice C++ core and the Node.js/JavaScript frontend.
  • Autonomous CI/CD: You develop "intelligent" pipelines that not only report errors but also analyze logs using AI and automatically suggest (or directly apply) patches for fragile legacy build steps.
  • Performance Guardrails: You implement "Continuous Profiling" in the build chain to detect 16ms frame budget violations before code even enters a Pull Request.

Qualifications

  • Excellent knowledge of Docker, GitHub Actions/Jenkins, and Makefile/CMake environments.
  • Expertise in Python, Go or Rust for building high-performance internal automation tools.
  • Profound experience with modern web toolchains (Vite, Webpack, esbuild) and optimizing large JavaScript monorepos.
  • Experience with vector databases or self-hosting LLMs (Ollama/LocalAI) is a significant plus.
  • The AI Factor: You are the team's "Prompt Architect" for infrastructure. You use models like Claude Opus 4.6 Max and specialized DevOps agents to automate routine operational work, focusing your human intelligence on systemic optimizations and creating a seamless "flow state" for the development team.
  • The Gaming Advantage: Experience in AAA game build engineering is particularly valuable to us. If you have managed automated pipelines for complex, cross-platform assets and codebases where "Build Time" and "Asset Cooking" are key KPIs, you bring exactly the DNA we are looking for in this high-performance office suite.
