Our Role

We're looking for a Senior Frontend Engineer to lead how our frontend applications get built, tested, and shipped. You'll write and review frontend code, make architectural decisions about our Next.js applications, and take ownership of the tooling, pipelines, and infrastructure that let our frontend teams move fast and ship with confidence.

This is a hands-on frontend role first you'll be in the codebase, working with delivery pods, reviewing PRs, and solving real product problems. But you'll also own the platform underneath it: CI/CD, deployment, observability, and developer experience for every frontend team in the business.

Role Responsibilities

Frontend Engineering

• Write, review, and ship production code across our Next.js applications, working directly alongside delivery pods.
• Make architectural decisions on SSR/ISR strategy, edge runtime usage, and caching behaviour for frontend applications.
• Set and champion frontend engineering standards - build tooling, code quality, testing practices, and performance budgets.
• Occasionally embed with a delivery pod for a sprint to support a specific initiative or unblock a hard problem.
• Mentor other engineers on frontend architecture, build, and deployment best practices.

Frontend Platform & Developer Experience

• Own the deployment strategy for SPAs and SSR applications, including CDN configuration, cache invalidation, and asset delivery.
• Build and maintain frontend-specific developer tooling: build configurations, local dev environments, preview environments, and service templates.
• Establish golden paths for new frontend services, so projects start with sensible defaults for builds, deploys, testing, and monitoring.
• Improve frontend observability: error tracking, performance monitoring, and Core Web Vitals, alongside broader monitoring, alerting, and logging.
• Manage package management strategy across npm/yarn/pnpm, internal registries, dependency management, and security scanning.
• Own and improve CI/CD pipelines, with a particular focus on build speed, caching, reliability, and fast feedback loops for frontend teams.
• Collaborate across all delivery pods to understand friction points and build self-service tooling that removes it.

Platform Infrastructure

• Build, maintain, and improve our Kubernetes platform, including cluster management, workload reliability, and resource optimisation.
• Write and maintain Infrastructure as Code (Terraform) for provisioning 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.
• Contribute to security hardening, cost optimisation, and capacity planning.

Role Requirements

• Strong, hands-on experience building and shipping production frontend applications with Next.js (or equivalent React frameworks), including SSR/ISR strategies and edge runtime considerations.
• Deep understanding of JavaScript/TypeScript build tooling (Webpack, Vite, esbuild, Turbopack, or similar).
• Experience owning or heavily contributing to CI/CD pipelines for frontend applications build times, caching strategies, artifact management.
• Solid understanding of how SPAs are built, bundled, and deployed (static hosting, CDN configuration, cache invalidation).
• Experience with npm/yarn/pnpm package management, dependency resolution, and registry configuration.
• Comfortable working with Node.js in a production context (SSR, build servers, tooling).
• Experience with monitoring and observability for frontend applications (error tracking, performance monitoring, Core Web Vitals).
• Familiarity with containerising frontend applications and deploying them to Kubernetes.
• Comfortable with Linux, shell scripting, and general infrastructure concepts.
• Experience with Infrastructure as Code (Terraform or similar).
• A genuine interest in developer experience, you notice friction and want to fix it, not just work around it.

Benefits of Working at Nexus Mods

• We work a 4-day week of 32 hours, with no reduction in pay.
• An allowance of £25 each month to spend on video games.
• Employee Assistance Programme.
• Private BUPA healthcare for you and your family.
• A very flexible training budget.
• Regular social events throughout the year. Participation is optional!

Diversity and Inclusion

We celebrate diversity and want you to bring your whole self to work.

Supporting an incredible community of tens of millions of users, we thrive on engaging as many views as possible to improve our platform. We see no reason why our culture should be any different.
