Founded by researchers from UC Berkeley's SkyLab, we're on a mission to measure and advance the frontier of AI for real-world use, and to build the foundation for everyone to understand, shape, and benefit from it.\nTens of millions of people use Arena each month to evaluate how frontier systems handle the work they actually do. The preferences they share power the most transparent, rigorous, and human-centered evaluations in AI. Leading AI labs, enterprises, and independent researchers rely on our work and open datasets to understand how models behave in real workflows: agentic coding, creative generation, professional productivity, and beyond. We go beyond leaderboards and decompose what human experience reveals about AI, so models advance toward the work people actually do.\nWe're a team of researchers, academics, builders, and creatives from UC Berkeley, Google, Stanford, and DeepMind. We seek truth, move fast, and value craftsmanship, curiosity, and impact over hierarchy. We're building a company where thoughtful, curious people from all backgrounds can do their best work together, in an office culture that radiates excellence, energy, and focus.\nAbout the Role\nWe'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.\nYou'll\nOwn the Arena blog end-to-end\n\nBuild and maintain marketing pages (product, features, resources, careers, campaign pages) in the same design system as the product\n\nImprove the public leaderboard frontend: tables, charts, filters, and the UX that makes evaluation data accessible\n\nKeep these surfaces fast, accessible, and indexable\n\nBuild CMS models and internal publishing tools so marketing and content can ship without waiting on engineering\n\nYou'll Have\n6+ years of software engineering, with most of that time on production frontend\n\nA portfolio or shipped work that shows high-craft public pages: marketing sites, content sites, or data-dense product UI\n\nDeep skill in React, TypeScript, Next.js, and CSS - you can implement complex layouts, motion, and responsive design\n\nEnough full-stack skill to work in a product codebase. You can read an API, extend a route, and follow the request lifecycle\n\nClear communication with designers, marketers, and engineers - you can defend a tradeoff and explain it to a non-engineer\n\nEvidence of shipping and iterating. You can describe a page or surface you owned, what happened after launch, and what you changed\n\nGenuine curiosity about AI evaluation and Arena's mission. You have looked at arena.ai and can say why this public surface matters\n\nBonus\nExperience with a headless CMS (Sanity, Contentful, or similar): content modeling, structured data, and the operational side of a live site\n\nLeaderboards, data tables, or visualization work (charts, ranking UIs, dense filterable tables)\n\nSEO, Core Web Vitals, structured data / JSON-LD\n\nAnimation (Motion, GSAP, or CSS) used with restraint\n\nYou've shipped without a dedicated PM - took a brief from marketing or design and drove it to production\n\nOur Tech Stack\nNext.js\n\nReact + TypeScript\n\nTailwind + ShadCN\n\nSanity CMS (blog and marketing pages)\n\nHonoJS\n\nWhat we offer\nWe offer competitive compensation aligned to the markets where our team members are based. The compensation range for each role is listed on its posting and will depend on the candidate's experience and work location.\n\nComprehensive health and wellness benefits, including medical, dental, vision, and additional support programs.\n\nThe opportunity to work on cutting-edge AI with a small, mission-driven team\n\nA culture that values transparency, trust, and community impact\n\nCome help build the space where anyone can explore and help shape the future of AI.\nArena Intelligence provides equal employment opportunities (EEO) to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability, genetics, sexual orientation, gender identity, or gender expression. We are committed to a diverse and inclusive workforce and welcome people from all backgrounds, experiences, perspectives, and abilities.","description_format":"text","description_chars":4323,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Recommendation Systems","Marketing & Sales AI"],"lifecycle":[{"event":"open","at":"2026-08-30T21:02:12Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 1","filings_12m":1,"filings_prev_12m":1,"green_card_filings_12m":0,"median_offered_wage_usd":252500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":70,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.78,"p_room":0.9,"age_days":49,"expected_fill_days":73,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/arena-software-engineer-marketing-web","json_url":"https://alion.io/job/arena-software-engineer-marketing-web.json","meta":{"generated_at":"2026-10-17T04:27:11Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":5808,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1017},"rest":"https://alion.io/mcp/rest/get_company?id=1017"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Farena-software-engineer-marketing-web"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Farena-software-engineer-marketing-web"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Farena-software-engineer-marketing-web"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/arena-software-engineer-marketing-web\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Farena-software-engineer-marketing-web"}]}
