Our client is looking for a Frontend technical architect for Digital Commerce Development.

As a Frontend Technical Architect, you will establish the framework for migrating our client's global B2B Product Store built on SAP Commerce Cloud from a Legacy JSP storefront to a modern, headless React/Next.js storefront hosted in Azure.

You will report to the Digital Commerce Development Manager and work closely with Back End architects, product owners, DevOps, UX and QA.

Key Responsibilities

• Architecture & Design
  • Define scalable and performable React/Next.js storefront architecture, integration layers, and BFF.
  • Where suitable, propose and architect micro frontends to be reused across other internal streams
  • Analyze the Front End architecture of existing React/Next.js applications and identify reusable components and practices to optimize development efforts.
  • Champion best practices for testing (unit, integration, E2E) and define testing strategy and frameworks
  • In collaboration with the performance engineer, design a performance-testing strategy (load, stress, SSR benchmarks). Define and establish best practices during development to achieve best performance.
  • Address SSR challenges

Technology Leadership

• Internationalization & Multisite
  • Architect solution for multi-language, multi-brand, and multi-country storefront requirements
  • Design deployment architecture in Azure: app services, CDN, storage accounts, and infrastructure-as-code.
  • Define CI/CD pipelines covering build, test, security scans, and blue-green or canary releases.
• Cloud & CI/CD

Based on existing setup for other React applications,

• State & Session Management
  • Specify strategies for client-side state (Redux/Context) vs. SSR, and secure session management (token renewal, cookie policies).
• Observability & Analytics
  • Integrate logging and monitoring (Application Insights or equivalent).
  • Architect analytics tracking (Google Analytics) to capture page views, performance timings, and business events.
• Accessibility & SEO
  • Define an accessibility testing strategy integrated into CI pipelines.
  • Ensure robust Server Side rendering for SEO (meta tags, sitemaps, hreflang).
• Composable Integrations
  • Lead integration with SAP Commerce CMS and propose a future headless CMS architecture (Contentstack).
  • Architect microfrontend boundaries and dynamic composition, managing version conflicts across micro-apps.
• Feature Management & Security
  • Design feature-toggle patterns (Split.io and SAP Commerce Back End capabilities) for phased rollouts.
  • Specify authentication/authorization flows for customer login and secure API calls.
• Governance & Mentorship
  • Establish coding standards, code-review processes, and Architectural Decision Records
  • Mentor Front End developers and run architecture workshops.
