The Opportunity
As Frontend Engineer, you will develop rich, high-performance web applications supporting our analytics platforms. You will work closely with UX designers, product managers, and backend engineers to deliver scalable and maintainable interfaces.
Key Responsibilities
- Analyse application requirements and translate designs into performant, modular frontend code
- Build and maintain interactive user interfaces using React.js with support for client-side and server-side rendering (e.g., Next.js)
- Implement templating engines (e.g., Handlebars, EJS, Nunjucks) to support server-rendered UI and dynamic content delivery
- Integrate with RESTful and GraphQL APIs, ensuring secure and efficient data flow
- Optimize frontend rendering and initial page load through modern SSR/CSR techniques, lazy loading, and hydration
- Enhance CDN performance by enabling content caching, edge rendering strategies, and route-based invalidation
- Implement and maintain JavaScript instrumentation for Real User Monitoring (RUM), tracking metrics such as First Contentful Paint, Time to Interactive, and long tasks
- Utilize Server-Side Includes (SSI) or modern equivalents (e.g., Edge-side Includes, CDN-based fragments, or streaming SSR) to dynamically inject reusable HTML blocks efficiently
- Develop frontend logic to assist backend services in measuring server responsiveness, latency, and perceived performance
- Troubleshoot frontend issues using browser dev tools, performance profilers, and network analysis
- Collaborate with DevOps to optimize CDN configurations and deployment pipelines for continuous delivery
- Maintain high coding standards and documentation for UI components and integration patterns
Comply with QHSE (Quality Health Safety and Environment), Business Continuity, Information Security, Privacy, Risk, Compliance Management and Governance of Organizations policies, procedures, plans, and related risk assessments.
