About The Position

We are looking for a web-first Full Stack Engineer who cares deeply about performance, rendering strategy, and building fast, discoverable user experiences. This role is primarily focused on React web development within a mixed-rendering environment (React SPA + Astro). You'll contribute to improving Core Web Vitals, search performance, and feature velocity — while operating in an AI-augmented development environment (L3+/AI-first) where agents are part of daily workflows. If you build something on web and it needs to exist on mobile, the expectation is that you help move it there.

Requirements

  • 3+ years building production web applications in React and TypeScript.
  • Strong understanding of rendering models (CSR, SSR, SSG, hydration).
  • Experience working on performance-sensitive surfaces.
  • Working knowledge of Core Web Vitals and frontend performance fundamentals.
  • Familiarity with technical SEO concepts (indexability, structured data, crawl behavior).
  • Comfort navigating existing codebases and shipping independently.
  • Experience directing AI agents for frontend-specific work (rendering strategies, SEO patterns, Core Web Vitals optimization) is a strong signal.
  • Willingness to work across web and mobile surfaces when needed.
  • Experience with React Native.

Nice To Haves

  • Experience with Astro or other mixed-rendering frameworks (Next.js, Remix, etc.).
  • Exposure to native iOS or Android development.
  • Marketplace, e-commerce, or high-traffic consumer product experience.
  • Experience working in experimentation-heavy environments.
  • Familiarity with using EdTest

Responsibilities

  • Build and ship production features in React (legacy SPA) with TypeScript.
  • Contribute to our Astro-based static and mixed-rendering architecture.
  • Implement performance optimizations that improve Core Web Vitals (LCP, CLS, INP).
  • Apply technical SEO best practices within features (rendering behavior, metadata, structured data, crawl-safe patterns).
  • Work within SSR, SSG, and hydration constraints — understanding tradeoffs and execution details.
  • Contribute to shared features in React Native when functionality overlaps with web.
  • Move features cross-platform when appropriate rather than relying on handoffs.
  • Collaborate with mobile engineers on platform-specific adjustments.
  • Contribute to performance-sensitive areas, including occasional native integrations as our tooling evolves.
  • Use AI agents for component generation, test writing, and performance optimization — our mixed-rendering architecture involves a lot of SSR/SSG scaffolding and rendering validation that benefits from agentic coding.
  • Participate in code reviews and architectural discussions.
  • Ship iteratively with a strong bias toward measurable performance impact.

Benefits

  • Gametime is committed to bringing together individuals from different backgrounds and perspectives. We strive to create an inclusive environment where everyone can thrive, feel a sense of belonging, and do great work together. As an equal opportunity employer, we prohibit any unlawful discrimination against a job applicant on the basis of their race, color, religion, veteran status, sex, parental status, gender identity or expression, transgender status, sexual orientation, national origin, age, disability or genetic information. We respect the laws enforced by the EEOC and are dedicated to going above and beyond in fostering diversity across our company.
