About The Position

Gametime is seeking Senior and Staff Front End Engineers to help build and scale the systems, applications, and experiences that power Gametime for millions of users. This role involves owning 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. The position requires driving technical decisions, mentoring other engineers, and partnering directly with stakeholders to define feature development. Gametime is also investing heavily in AI, offering opportunities for engineers to experiment, automate, and shape how AI transforms products and workflows.

Requirements

Experience with React Native and TypeScript or cross-platform mobile development.
Familiarity with Next.js or similar SSR/SSG frameworks and edge-rendering patterns.
Proficient with modern state management (Zustand, Redux Toolkit, React Query, or similar) and REST/GraphQL data-fetching patterns.
Strong UI engineering fundamentals, including responsive/adaptive design, accessibility (WCAG 2.1 AA), cross-browser and cross-platform compatibility, and thoughtful use of motion and animation.
Comfortable with frontend testing: unit, integration, and end-to-end (Jest, React Testing Library, Playwright or Cypress).
Experience building or maintaining a shared design system or component library at team scale.
Contributions to open-source projects or public technical writing that demonstrates depth of craft.
Demonstrated ownership of consumer-facing products at a meaningful scale of millions of users or transactions.
Experience with experiment-driven product development, using A/B testing and quantitative analysis to validate hypotheses and guide iteration.
Collaborative mindset with a passion for solving problems and building great products.

Nice To Haves

Exposure to web3 or digital-goods purchasing flows (not required—but we’re curious).
AI curiosity and fluency with tools like Cursor, Claude, or ChatGPT is a plus.
Prior work in a two-sided marketplace, ticketing, or high-transaction-volume e-commerce product is preferred.

Responsibilities

Own high quality end-to-end delivery of major consumer-facing features—from technical design through launch, experimentation, and iteration.
Drive frontend architecture decisions: component design, state management, data-fetching patterns, and performance budgets.
Build and optimize conversion-critical flows (event discovery, seat selection, checkout) with a relentless focus on speed, reliability, and UX quality.
Design, instrument, and interpret A/B experiments in partnership with Product and Data; use results to validate and sharpen product decisions.
Instrument frontend observability—error tracking, performance monitoring, real-user metrics—and act on what you find.
Contribute to design-system components and front-end standards that accelerate the whole team.
Mentor junior and mid-level engineers through code review, pairing, and technical leadership on shared initiatives.
Collaborate with mobile, backend, and platform teams to deliver cohesive cross-platform experiences.
