Key responsibilities

• AnalyseOpenStack-style services and surrounding components to map APIs, configuration flows, service dependencies, database usage, and operational assumptions.
• Use AI coding agents to accelerate code navigation, call-flow reconstruction, interface analysis, and technical documentation across large multi-repository environments.
• Support build and test diagnosis for selected services, including dependency resolution, container build issues, runtime configuration gaps, and reproducibility problems.
• Create structured service handover artefacts such as service maps, dependency notes, API summaries, risk observations, and onboarding documents for receiving teams.
• Work with DevOps, testing, security, and architecture specialists tovalidateAI-assisted findings and turn them into actionable engineering backlog items.
• Identifytechnical debt, maintainability risks, hidden coupling, missing documentation, and areas where automated analysis should be complemented by expert review.

Examples of market tools, models, and SDLC platforms expected

• AI coding environments such as Cursor, Windsurf, Claude Code, Cline, Continue, or VS Code-based AI extensions for large-repository engineering workflows.
• Coding-capable models such as DeepSeek Coder, Qwen/Qwen-Coder,CodeGeeX,StarCoder, Code Llama, Mistral, or other approved open-weight and enterprise model stacks.
