Joblaze insights
Quick facts
From the original posting
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.
Own the Arena blog end-to-end
Build and maintain marketing pages (product, features, resources, careers, campaign pages) in the same design system as the product
Improve the public leaderboard frontend: tables, charts, filters, and the UX that makes evaluation data accessible
Keep these surfaces fast, accessible, and indexable
Build CMS models and internal publishing tools so marketing and content can ship without waiting on engineering
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
Enough full-stack skill to work in a product codebase. You can read an API, extend a route, and follow the request lifecycle
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
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
You've shipped without a dedicated PM — took a brief from marketing or design and drove it to production
Next.js
React + TypeScript
Tailwind + ShadCN
Sanity CMS (blog and marketing pages)
HonoJS
