About the role

We're looking for a frontend-specialized Software Engineer to own Arena's public web surfaces: the blog, marketing pages, and the leaderboard UI that millions of people use to judge how AI models perform. You'll Own the Arena blog end-to-end — Next.js, Sanity CMS, content models, publishing workflows, and the templates authors use every weekBuild and maintain marketing pages (product, features, resources, careers, campaign pages) in the same design system as the productImprove the public leaderboard frontend: tables, charts, filters, and the UX that makes evaluation data readable at a glanceKeep these surfaces fast, accessible, and indexable — Core Web Vitals, SEO, structured data, and the i18n we already runBuild CMS models and internal publishing tools so marketing and content can ship without waiting on engineering for every copy change

Requirements

  • 6+ years of software engineering, with most of that time on production frontend
  • A portfolio or shipped work that shows high-craft public pages: marketing sites, content sites, or data-dense product UI
  • Deep skill in React, TypeScript, Next.js, and CSS — you can implement complex layouts, motion, and responsive design with precision
  • Enough full-stack skill to work in a product codebase. You can read an API, extend a route, and follow the request lifecycle. You are not a backend specialist, and you do not need to be
  • Clear communication with designers, marketers, and engineers — you can defend a tradeoff and explain it to a non-engineer
  • Evidence of shipping and iterating. You can describe a page or surface you owned, what happened after launch, and what you changed
  • Genuine curiosity about AI evaluation and Arena's mission. You have looked at arena.ai and can say why this public surface matters

Qualifications

  • Leaderships experience
  • Experience with a headless CMS (Sanity, Contentful, or similar): content modeling, structured data, and the operational side of a live site
  • Leaderboards, data tables, or visualization work (charts, ranking UIs, dense filterable tables)
  • SEO, Core Web Vitals, structured data / JSON-LD
  • Animation (Motion, GSAP, or CSS) used with restraint

Skills

  • Frontend development

Benefits

  • The opportunity to work on cutting-edge AI with a small, mission-driven team
  • A culture that values transparency, trust, and community impact
