About Nexus Mods
Established in 2001, Nexus Mods is the largest video game modding platform on the internet - a household name in the PC gaming ecosystem.
- 71M+ registered members
- 800K+ mods for 4,000+ games

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 Platform Engineer to join our Platform Engineering team, with a primary focus on Vortex, our open-source mod manager used by millions of gamers. Vortex is an Electron desktop application built with TypeScript, React, Redux, and Node.js.
Most of this role is owning the build, release, and developer infrastructure for Vortex: CI/CD pipelines, build toolchain, packaging, code signing, auto-update, testing infrastructure, and developer experience across Windows and Linux. Alongside that you'll contribute to the rest of the Platform team's work: CI/CD for other services, observability, on-call rotations, and Infrastructure as Code. You'll work closely with the App engineers to improve how Vortex is built, packaged, and shipped.
- Own and improve CI/CD pipelines across all services, with Vortex as the primary focus (GitHub Actions).
- Own and optimise the Vortex build toolchain: pnpm/Nx monorepo task orchestration, TypeScript compilation, module bundling (Webpack 5, migrating to Rolldown), Electron packaging via electron-builder, and native module compilation (node-gyp, @electron/rebuild).
- Set up and maintain testing infrastructure for Vortex: unit and integration testing (Vitest), and end-to-end testing (Playwright).
- Design and maintain the Vortex release pipeline: versioning, signing, auto-update infrastructure, staging/beta channels, and installer generation.
- Improve the developer experience for App engineers: local development setup (Windows and Linux), fast rebuild and reload cycles, debugging tooling, and dependency strategy (pnpm package management, native dependency builds, security scanning).
- Support ongoing Electron and Node.js runtime upgrades, ensuring native module compatibility and minimising breakage in the extension ecosystem.
- Respond to infrastructure incidents, participate in on-call rotations, contribute to post-incident reviews, and write/maintain Infrastructure as Code (Terraform) for the cloud resources our services depend on.
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.

Role Requirements

- Experience building and optimising CI/CD pipelines for complex application builds across Windows and Linux (GitHub Actions or similar).
- Familiarity with pnpm and monorepo tooling (Nx or similar).
- Experience with JavaScript bundlers (Webpack required; experience with Rolldown, esbuild, or other bundler migrations a plus).
- Experience setting up and maintaining testing infrastructure for desktop applications, including E2E (Playwright or similar).
- Experience with at least one major cloud provider (we use a multi-cloud setup).
- Experience with monitoring and observability tools (Prometheus, Grafana, or similar).
- Understanding of secrets management and infrastructure security principles.
