Zusammenfassung

ELCA, a leading Swiss IT company, offers a six-month internship in Zürich starting Spring 2027. You will explore agentic AI to uncover hidden business rules in a legacy .NET/VB6 codebase and design a prototype agent that autonomously navigates the codebase while cross-referencing modules.

You will extract and document the business rules, flag uncertainties for expert review, and validate results with domain experts, culminating in a repeatable modernization methodology.

Qualifikationen

• Bachelor or Master in Computer Science or related discipline.
• Programming experience in .NET; VB6/VB.NET knowledge preferred.
• Familiar with static code analysis.
• Experience with multiple AI engines and LLMs.
• Fluent in English; German or French is required.

Aufgaben

• Research and compare agentic AI approaches that combine LLM-driven agents with static and program analysis to mine business rules from legacy code.
• Select the most promising approach and AI engines, including options beyond LLMs.
• Design and build a prototype agent that navigates a representative legacy .NET/VB6 codebase on its own and cross-references related modules.
• Extract and document business rules, turning knowledge that only lives in the code into a clear specification that experts can review.
• Add mechanisms that flag uncertain findings for expert review.
• Validate your results with domain experts and use their feedback to improve the agent.
• Propose a repeatable methodology and best practices for using agentic knowledge mining before modernization, replacement or retirement decisions.
• Lay the groundwork for a scalable Legacy Modernization Assessment offering for clients across the market.
