• Support the platform through deployment, monitoring, and maintenance activities

Required Skills and Experience

• 10+ years of experience in software development, preferably in large-scale applications

• Expert-level knowledge of JavaScript (Vanilla JS), CSS, HTML, and Web Components

• Solid experience with Node.js, Front End build tools (Webpack, Rollup), and browser APIs

• Familiarity with class-based components (eg, React Classes, LIT)

• Experience designing APIs and working in cross-functional environments

• Strong understanding of Front End architecture, SPA, and SSR/SSG patterns

• Proficiency in CI/CD pipelines (preferably Azure DevOps)

Nice to Have
