We own the shared component libraries and design system, the build and release tooling every engineer touches daily, and the performance, accessibility, and observability standards that hold across our client surfaces. Much of the work is internal tooling that keeps a large monorepo pleasant to work in. We partner closely with product teams to make the right thing the easy thing.</span> </p> <p><span data-contrast="auto">The team also builds our server-driven UI service, a TypeScript GraphQL subgraph that lets product teams change what the iOS, Android, and web clients render without shipping an app release. The role spans both the monorepo and that service, so it is a genuine mix of front-end and backend GraphQL work.</span> <br><span data-ccp-props="{"201341983":0,"335559739":0,"335559740":276}"> <br></span><strong><span data-contrast="auto">About the Work</span></strong><span data-ccp-props="{"201341983":0,"335559739":0,"335559740":276}"> </span></p> <ul> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1"><span data-contrast="auto">Design and evolve GraphQL schemas in a federated graph, including the server-driven UI contracts our mobile and web clients render.</span> <ul> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Treat those schemas as a versioned contract shared with released mobile apps: classify breaking changes, coordinate migrations with the iOS, Android, and web leads, and keep generated client models in sync.</li> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Develop, scale, and optimize the GraphQL APIs, RPC endpoints, and SQL queries behind our web surfaces.</li> </ul> </li> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Build front-end applications and shared libraries with React and TypeScript. <ul> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Build web applications that are fast and accessible to everyone.</li> </ul> </li> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Partner with product and design to architect and ship customer-facing features.</li> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Use observability tooling to diagnose issues and improve the experience for guests. <ul> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Set up and refine monitoring and alerting in DataDog for the systems you own.</li> </ul> </li> <li data-leveltext="" data-font="Symbol" data-listid="9" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"
