Senior and Staff Front End Engineer

Join Gametime as a Senior or Staff Front End Engineer and help build and scale the systems, applications, and experiences that power Gametime for millions of users. You will own a significant surface area of our consumer-facing web and mobile web experience, working closely with Product, Design, and backend engineers to ship features that move core metrics. This is a high-ownership role on a small, focused team where you will drive technical decisions, mentor other engineers, and partner directly with stakeholders to define how features get built.
