We’re currently focused on product modernisation, driving growth and building infrastructure for the next 10 years of community-powered modding.
Our Role:
We're looking for a Senior Frontend Platform Engineer. Someone who sits at the intersection of frontend engineering and platform infrastructure. You've shipped and operated production of Next.js applications, and now you want to own the infrastructure that powers them. You'll bridge the gap between our frontend engineering teams and our platform, ensuring that the build, test, and deployment pipeline for our frontend applications is fast, reliable, and well-supported.
- 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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

- 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.
