Principal Web Developer

The Principal Web Developer owns the architecture, security and technical standards of K3's web platform, based in our Kuala Lumpur office. It exists to close a specific gap: K3's web estate is moving from WordPress to a headless CMS (Contentful) and integrating into Salesforce and the group data platform, and no role in the group currently owns that decision end to end. The Principal Web Developer sets the CMS platform architecture, defines integration and API/MCP standards, holds security accountability for the web estate, and leads the developers and technical SEO managers delivering against it. Marketing continues to set priorities and roadmap through its existing dotted-line relationship with the delivery team; this role owns how that roadmap gets built, not what gets built first. TOOLS & PLATFORMS Contentful — content modelling, Content Management API, GraphQL Content API, App Framework, webhooks, environments & Environment Aliases, Live Preview SDK; Salesforce integration patterns; Boomi (coordination with Platform Engineering integration layer).React, Next.js, Node.js/Python; REST & GraphQL APIs; AWS, Azure, CDN; API/MCP design standards; security tooling (access control, vulnerability management, patch governance). COMMERCIAL OBJECTIVES Successful, on-time, on-budget delivery of the headless CMS migration (Contentful).Secure, governed integration between the web estate, Salesforce and the group data platform.Site health, performance and CVR uplift across all K3 brand sites on the platform.Zero security or data-governance incidents attributable to the web estate.
