Developer (Legacy Specialist & AI Expert)

The Project: Internal Support Tools Evolution  

You are joining an initiative focused on the evolution modernization of the Internal Application Landscape. This project involves the strategic transition of well-known cloud services and architectures into a next-generation AI-augmented and cloud-native software landscape. 

Our goal is not simply to maintain the existing system but to proactively transform itensuring sovereignty high-performance scalability and seamless handover readiness through disciplined engineering. 

Our Engineering Philosophy 

We operate at the intersection of Legacy Stability and Modern Innovation. Our approach is defined by: 

• AI-Augmented Engineering: We utilize advanced AI development environments (such as Cursor Windsurf and Claude Code) and cutting-edge model families to accelerate code comprehension refactoring and documentation. 

• Disciplined SDLC Patterns: We move beyond traditional development by implementing repeatable evidence-based SDLC patterns. Every change is backed by structured engineering evidence and rigorous automated testing. 

• The Strangler Fig Modernization: We prioritize risk-mitigated evolution using sophisticated patterns to wrap refactor and eventually replace legacy components. 

• High-Seniority Autonomy: We operate as a lean highly autonomous unit. We value technical detectives who can navigate ambiguity and perform deep reverse engineering. 

Mission

To drive the technical execution of both high-impact feature development and the deep-dive modernization of our ecosystem. You will be a specialist who finds satisfaction in solving complex puzzles utilizing AI-assisted tools to accelerate the modernization of our core systems. 

Role Focus

This role focuses on high-complexity coding deep reverse engineering and AI-augmented productivity. You will work in the trenches of the legacy codebase extracting logic and implementing modern testable solutions using the latest AI-powered development environments. 

Key Responsibilities 

• Complex Feature & Refactoring: Design and implement sophisticated new functionalities within the ecosystem ensuring seamless integration with legacy components. 

• Deep Reverse Engineering: Analyze and deconstruct complex undocumented or spaghetti legacy code to understand underlying business rules and technical flows. 

• AI-Augmented Coding: Proactively utilize AI coding assistants and advanced environments (e.g. Cursor Windsurf Claude Code or VS Code extensions) to accelerate code comprehension documentation and refactoring. 

• Robust Testing & Stability: Write high-quality unit and integration tests to wrap legacy modules providing a safety net for all refactoring efforts. 

• Technical Troubleshooting: Act as a high-level escalation point for complex bugs and performance bottlenecks within the legacy environment. 

• Internal Tooling: Utilize Microsoft PowerApps to build rapid lightweight administrative or maintenance utilities to support the development and operations lifecycle. 

Qualifications :

• Experience: 6 years of professional software development experience with deep expertise in /C# stack. 

• Legacy Navigation: Proven experience working with versions (e.g. .NET Framework) and managing the complexities of monolithic architectures. 

• AI Tooling Proficiency: Hands-on familiarity with AI coding assistants prompt engineering or local model experimentation. 

• Core Skills: Mastery of SOLID principles design patterns and advanced debugging/profiling techniques. 

• Testing Mindset: Strong commitment to TDD and automated testing (Unit/Integration) to protect the legacy core.
