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.

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.
