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.

• 80M+ registered members
• 980K+ mods for 5,500+ games
• 26B+ mod downloads

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 x4 Senior Full Stack Engineers to join our Engineering team, working on Vortex, Nexus Mods’ flagship desktop mod manager. You’ll help build and improve an application used by millions of gamers, powering downloads, deployments, and conflict resolution across our supported games.

Vortex is a desktop app, currently Windows-first with Linux on the roadmap. You’ll join our existing product-led teams, making sure each pod has engineers who can actively deliver and build features.

What You’ll Be Working On

• Developing and improving Vortex on Windows, supporting the wider gaming industry
• Tackling practical engineering challenges around game support, Vortex functionality, and desktop development
• Improving the functionality and user experience of our existing application

Role Responsibilities

• Build and maintain features across the frontend, backend, and integration layers of a desktop app used by tens of millions of users on varying hardware and OS configurations.
• Work across the delivery lifecycle, from prototyping to multi-sprint delivery of new game support and major workflow changes.
• Tackle hard technical problems: performance regressions, race conditions, complex state bugs.
• Evolve local data, configuration, and user profiles safely across releases.
• Collaborate with other teams and review contributions from community and internal developers.
• Contribute to the public extension API, balancing third-party freedom with a sound permission model.
• Diagnose field issues using crash reports, telemetry, and logs.
• Write clean, well-tested code and uphold high standards across CI/CD, packaging, and documentation.
• Share knowledge and support other engineers across pods.

Role Requirements

_Must-haves:_

• A genuine passion for gaming and an understanding of gaming culture (a hard requirement).
• Strong full-stack JavaScript / TypeScript experience in production.
• Strong React experience, including state management.
• Solid Node.js and wider JavaScript ecosystem experience, including async patterns, streaming I/O, and child processes.
• Experience developing desktop applications, and a genuine interest in desktop over purely web-based products.
• Experience with our current technology stack.
• Senior-level experience on substantial, consumer-facing systems at scale. Desktop, gaming, or creator tooling is ideal, but other backgrounds are welcome.
• Solid system design and API design skills, with an eye for backwards compatibility.
• Experience debugging production software on machines you don’t control.
• Hands-on CI/CD experience.
• Excellent communication skills and comfort working cross-functionally.
• Ability to balance speed, quality, and pragmatism in a long-lived codebase with active community contributors.

_Bonus Skills:_

• Hands-on Electron experience (less onboarding, faster ramp-up), including Windows and Linux platform behaviour.
• Modding experience or familiarity with Nexus Mods. Not essential, as we provide internal training.
• Packaging, code signing, and auto-update experience (electron-builder, NSIS, Flatpak, or equivalent).
• Client-side authentication and download/distribution experience.
• Background in launchers or content distribution clients (Steam, Epic, GOG Galaxy, Battle.net, modding tools).
• Experience taking a Windows-first app to Linux, or maintaining parity.
• Open source or external community contributor experience.
• Understanding of gaming ecosystems: file formats, save management, load orders, plugin systems.
• Familiarity with Bethesda Creation Engine, FOMOD, Wabbajack, or similar standards.

Benefits of Working at Nexus Mods

Benefits

• 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!
