Role Requirements

• Strong understanding of JavaScript/TypeScript build tooling and ecosystems (Webpack, Vite, esbuild, Turbopack, or similar).
• Experience deploying and operating Next.js applications in production, including SSR/ISR strategies, edge runtime considerations, and caching behaviour.
• Experience with npm/yarn/pnpm package management, dependency resolution, and registry configuration.
• Experience building and optimising CI/CD pipelines for frontend applications (build times, caching strategies, artifact management).
• Deep understanding of how SPAs are built, bundled, and deployed to production (static hosting, CDN configuration, cache invalidation).
• Experience with Node.js in a production context (SSR, build servers, tooling).
• Familiarity with containerising frontend applications and deploying them to Kubernetes.
• Experience with monitoring and observability for frontend applications (error tracking, performance monitoring, Core Web Vitals).
• Understanding of CDN configuration, edge caching, and asset delivery optimisation.
• Comfortable with Linux, shell scripting, and general infrastructure concepts.
• Experience with Infrastructure as Code (Terraform or similar).
• Familiarity with monorepo tooling (Nx, Turborepo, or similar).
• Experience with GitLab CI or similar CI/CD platforms.
• Understanding of GitOps workflows (FluxCD, ArgoCD).
• Experience with Kubernetes beyond just deploying frontend apps (general cluster understanding).
• Familiarity with Cloudflare (Workers, Pages, R2, CDN configuration).

Role Responsibilities

• Design and maintain the deployment strategy for SPAs and SSR applications, including CDN configuration, cache invalidation, and asset delivery.
• Own and improve CI/CD pipelines across all services, with particular ownership of frontend application pipelines (build speed, caching, reliability, developer feedback loops).
• Build and maintain frontend-specific developer tooling: build configurations, local development environments, preview environments, and service templates.
• Establish and maintain golden paths for frontend service creation, ensuring new projects start with sensible defaults for builds, deploys, testing, and monitoring.
• Build and improve observability: monitoring, alerting, dashboards, and logging across all services, including frontend-specific observability (error tracking, performance monitoring, Core Web Vitals).
• Manage package management strategy: npm/yarn/pnpm configuration, internal package registries, dependency management, and security scanning.
• Collaborate with frontend engineers across all delivery pods to understand pain points and reduce friction in their workflows.
• Create and maintain self-service tooling, templates, and golden paths that enable delivery pods to work independently.
• Build, maintain, and improve our Kubernetes platform, including cluster management, workload reliability, and resource optimisation.
• Write and maintain Infrastructure as Code (Terraform) for provisioning and managing cloud resources.
• Manage and evolve our GitOps workflows (FluxCD) for continuous delivery.
• Respond to infrastructure incidents, participate in on-call rotations, and contribute to post-incident reviews.
• Write clear documentation and runbooks so other engineers can understand and operate the infrastructure.
• Support delivery pods with infrastructure queries, troubleshooting, and guidance.
• Contribute to security hardening, cost optimisation, and capacity planning.
• Mentor other engineers on frontend build and deployment best practices.
• Occasionally embed with a delivery pod for a sprint to support a specific initiative.
