Next.JS Developer

Frontend/Backend:Next.js (TypeScript/JavaScript) Infrastructure:Google Cloud Platform (GCP) Containerization/Compute:Cloud Run Database:PostgreSQL (managed via Cloud SQL) DevOps/Tooling:GitHub/GitLab, CI/CD pipeline, monitoring tools Critical Tooling:Feature Flag systems (e.g., LaunchDarkly, proprietary solution)Key Responsibilities: 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.
