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. Bonus Skills: * 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. ## Description * 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. ## Related Videos - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [WeAreDevelopers LIVE - "Fun and games - and all that comes with it", Back to BASIC & more](https://www.wearedevelopers.com/videos/1719-wearedevelopers-live-fun-and-games-and-all-that-comes-with-it-back-to-basic-more) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Dev Digest 129 - Now that's what I call private data!](https://www.wearedevelopers.com/magazine/468-dev-digest-129-now-that-s-what-i-call-private-data)
