· Technical Debt Strategy: Collaborate with the team to identify, prioritize, and define the scope of technical debt initiatives (e.g., refactoring brittle components, upgrading dependencies, improving testing coverage, standardizing deployment practices). · Code Modernization: Execute complex refactoring and modernization of existing Next.js codebase to improve readability, performance, and adherence to modern architectural patterns. · System Optimization: Analyze and optimize the performance of our Cloud Run deployments and PostgreSQL queries in Cloud SQL. · Testing and Stability: Implement robust unit, integration, and end-to-end tests to prevent regressions during the debt reduction process. · Safe Deployment: Utilize feature flagging techniques extensively to manage the rollout of substantial code changes, minimizing risk and allowing for rapid rollback if necessary. · Documentation: Create and maintain high-quality documentation for the improved architecture and refactored components. Required Qualifications: · Experience: 5+ years of professional experience as a Software Engineer, with a significant tenure operating in a Senior capacity. · Next.js Expertise: Deep, hands-on experience developing, deploying, and maintaining production applications using Next.js (preferably with TypeScript). · Cloud Infrastructure: Proven familiarity with deploying and managing containerized applications on GCP, specifically using **Cloud Run**. · Database Proficiency: Strong working knowledge of PostgreSQL, including performance tuning, schema optimization, and writing efficient SQL queries within a Cloud SQL environment. · Legacy Code Mastery: Demonstrated ability to analyze, debug, and safely modify/improve large, complex, and potentially brittle existing codebases. · Feature Flagging: Extensive practical experience integrating and managing features using feature flags to decouple deployment from release and mitigate risks associated with major architectural changes
