• Collaborate with architects and engineers to define safe and incremental refactoring strategies, and lead their execution across the team.
• Lead code reviews and mentor other engineers, promoting engineering best practices across the team.
• Communicate directly with client stakeholders to explain technical decisions and refactoring trade-offs.
• Contribute to architectural discussions when relevant, without introducing major technology changes.
• Improve unit testing coverage and support validation of refactored functionality.
• Document technical findings, design decisions, and refactoring approaches for future maintainability.

Qualifications

Skills & Experience
