Senior Full Stack Engineer

• 71M+ registered members
• 800K+ mods for 4,000+ games
• 21B+ mod downloads

Role Requirements

• Strong senior-level application engineering experience on substantial, consumer-facing systems at scale. Ideally desktop, gaming, or creator tooling - but strong candidates from other backgrounds are very welcome.
• Deep TypeScript / modern JavaScript experience in production.
• Strong React experience, including state management.
• Solid Node.js fundamentals - async patterns, streaming I/O, child processes.
• Strong system design skills - module boundaries, plugin/extension models, data flow, persistence.
• Experience designing APIs (public or internal) with an eye for backwards compatibility.
• Experience debugging production software on machines you don't control - crash reports, log analysis, environment-specific issues.
• 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.
• Comfort learning new frameworks and paradigms quickly - you'll be ramping up on Electron's main/renderer model on the job if you haven't used it before.

• Hands-on production experience with Electron - understanding of the main vs. renderer split, and platform-specific file system, permissions, and OS integration behaviour across Windows and Linux.
• Packaging, code signing, and auto-update experience (electron-builder, NSIS, Flatpak, or equivalent).
• Experience with authentication and download/distribution systems on the client side.
• Background in high-scale desktop platforms, launchers, or content distribution clients (Steam, Epic, GOG Galaxy, Battle.net, modding tools).
• Experience taking a Windows-first app to Linux, or maintaining Windows/Linux parity in production.
• Experience working on open source projects or with external community contributors.
• Understanding of gaming ecosystems: file formats, save management, load orders, plugin systems.
• Experience building tools for creators or modding/UGC communities.
• Familiarity with Bethesda Creation Engine, FOMOD, Wabbajack, or similar modding standards.
• A passion for games and mods, in whatever form that takes.

Role Responsibilities

• Own significant areas of the application - designing, building, and maintaining robust, scalable 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 full delivery lifecycle, from discovery and prototyping through technical planning and 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, without data loss or corruption.
• Collaborate with other engineering teams on end-to-end features, and review contributions from both community and internal developers.
• Help steward the public extension API, balancing third-party developer freedom with a sound trust/permission model.
• Improve observability and operational standards; diagnose field issues using crash reports, telemetry, and logs.
• Drive best practices in performance, state management, security, accessibility, and internationalisation.
• Write clean, well-tested code and uphold high standards across CI/CD, packaging, and documentation.
• Help mentor other engineers and share standards across pods.
