Job Description

Key responsibilities 

  • Analyse OpenStack-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 to validate AI-assisted findings and turn them into actionable engineering backlog items. 

  • Identify technical 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. 

  • OpenStack-related components and patterns such as Nova, Neutron, Cinder, Keystone, Glance, Horizon, Heat, placement services, message buses, and Kubernetes integrations. 

  • Supporting engineering tools such as Git, GitLab, Jenkins, Docker, Kubernetes, Helm, ArgoCD, Python tooling, API clients, log analysis tools, and dependency scanners.

Qualifications

  • 5+ years in software engineering, cloud platform engineering, DevOps-oriented development, or technical software handover roles. 

  • Strong Python skills plus experience in at least one backend or systems language such as Go, Java, C, C++, or Rust. 

  • Practical experience using AI-assisted development tools for codebase exploration, documentation generation, refactoring support, or build issue triage. 

  • Good understanding of OpenStack-derived architectures, cloud control planes, distributed services, APIs, CI/CD, container delivery, and Linux-based environments. 

  • Strong analytical discipline for separating AI suggestions from evidence-backed findings and producing concise technical outputs for engineering stakeholders. 

  • Comfortable working in confidential enterprise environments with high expectations on traceability, quality of documentation, and structured handover readiness.
