In this role you work at the heart of the organization, where game teams, platform partners, and products come together. Using a lean, framework-free TypeScript codebase and our shared integration libraries, you help keep our games platform-agnostic while still building the platform-specific features that make each integration feel native. Things like notifications, badges, achievements, and save states. You contribute not only by shipping integrations, but by shaping the tools and abstractions the whole engineering team relies on. Together with the rest of the team, you will share technical ownership of the systems and processes that bring our games to new and existing platforms. You will work closely with game teams, product and publishing colleagues, and external partners to deliver reliable integrations, smooth launches, and a consistent player experience. Your responsibilities will include: * Owning and evolving the shared integration technology that supports multi-platform deployment and keeps our games largely platform-agnostic. * Extending and refining our platform abstraction libraries to support new platforms, SDK features, and deployment requirements. * Integrating and maintaining third-party SDKs for services such as authentication, payments, analytics, advertising, and platform features. * Bringing games to new platforms, from technical discovery and planning through implementation, debugging, launch, and ongoing support. * Translating platform documentation and partner requirements into clear technical solutions and reusable capabilities. * Coordinating with internal developers and external teams to align requirements, priorities, dependencies, and delivery timelines. * Reviewing and improving code to ensure quality, consistency, and maintainability across integrations. * Investigating complex integration issues methodically and resolving their root causes. * Profiling game and integration performance and implementing improvements where needed. * Keeping SDKs and integration-related components up to date, compliant, secure, and stable. * Supporting cross-functional teams with technical expertise during planning, implementation, and rollout. * Staying informed about relevant developments in platform integration, game publishing, and web technology. ## 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) - [Lessons learned from building a thriving Vue.js SaaS application](https://www.wearedevelopers.com/videos/1666-lessons-learned-from-building-a-thriving-vue-js-saas-application) - [The Resilience of the World Wide Web](https://www.wearedevelopers.com/videos/1281-the-resilience-of-the-world-wide-web) - [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) - [Common Mistakes in Vue.js and How to Avoid Them](https://www.wearedevelopers.com/videos/958-common-mistakes-in-vue-js-and-how-to-avoid-them) - [WeAreDevelopers LIVE - CSS is DOOMed](https://www.wearedevelopers.com/videos/1851-wearedevelopers-live-css-is-doomed) ## Related Articles - [Dev Digest 136 - No JS(on) of mine](https://www.wearedevelopers.com/magazine/482-dev-digest-136-no-js-on-of-mine) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss) - [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 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 105 - Security First](https://www.wearedevelopers.com/magazine/393-dev-digest-105-security-first)
