Full Stack Developer .Net

As an individual contributor and key technical authority, you will be responsible for the strategy, technical health, and execution of modern front-end development and full-stack solutions at GCC. The ideal candidate will have deep expertise in React, Next.js, and headless CMS architectures-serving as our resident Optimizely expert-with a proven track record of leading digital initiatives in a dynamic and fast-paced environment. You will focus purely on code quality, system architecture, and mentoring, driving exceptional results through best practices without the responsibilities of direct people management.

What You’ll Do

Technical Leadership: Demonstrate technical leadership with hands-on accountability for the end-to-end delivery of modern web solutions. You will guide solutions from technical design through development, automated testing, deployment, and ongoing maintenance.

Modern Web Architecture: build sophisticated, customer-facing web applications using Next.js and React. You will leverage server-side rendering, static site generation, and other modern web patterns to deliver exceptional performance and user experience.

System Health & Metrics: Drive system improvements by tracking performance against KPI and SLA targets for each API using internal System Metrics Baselines. You will regularly use the Architecture Decision Record (ADR) process, the Richardson Maturity Model, and internal System Quality Guidelines to measure and maintain API and overall system health.

Full-Stack Collaboration: Collaborate with back-end teams working with C#, .NET Core, SQL, Docker, and Redis to create cohesive full-stack solutions. You will deploy modern web applications to the cloud using Azure, implementing CI/CD pipelines and ensuring optimal performance and reliability.
