At Beast Industries, we believe in the transformative power of digital media and its potential to entertain, educate, and effect positive change. Our commitment to innovation, creativity, and philanthropy drives us to explore new frontiers, create unforgettable experiences, and build a legacy that inspires future generations.\nSenior Frontend Engineer\nThe Opportunity\nWe're doing an AI-first engineering rebuild for a company that already has an audience of 100M+ people. This is a zero-to-one build with no legacy constraints, so you get to define a modern frontend stack from scratch instead of inheriting a tangle of old code. You're here to build customer-facing experiences that millions of people actually use.\nThe Product\nYou'll design, build, and evolve the user-facing applications at the center of the MrBeast membership ecosystem. The work is fast and AI-first, in close partnership with product and design. That means:\nBuild scalable, performant frontend architectures and reusable components for consumer apps with the potential to reach 100M+ people.\nMake core user journeys fast: page-load times and frontend latency are numbers you own and move.\nUse AI coding agents and modern tooling as the baseline for how you ship, not the exception.\nWhat You'll Do\nDesign and implement scalable frontend architectures for complex web applications.\nBuild and maintain reusable UI components and design-system integrations that other engineers ship on.\nPartner with product managers and designers to turn requirements into clean, high-quality experiences.\nLead technical design discussions and own architectural decisions within your domain.\nOptimize for performance, accessibility, responsiveness, and usability across core flows.\nSet and enforce frontend standards and patterns, and drive their adoption across teams.\nMentor engineers through code reviews and technical guidance, and resolve the gnarly production issues.\nWho You Are\nAI-Native: You're already using AI coding agents daily to multiply your output, and modern tooling is second nature.\nDeep Frontend Builder: Typically 8+ years in software engineering with serious frontend depth, building modern web apps in JavaScript and TypeScript and maintaining scalable architectures in production.\nPerformance Minded: You have a real command of performance optimization, testing strategy, accessibility, and web standards, and you can prove the wins with metrics.\nOwner: You take a problem from design through production support, and you raise the bar for the engineers around you.\nBonus points for building and maintaining design systems, modern frameworks like React, Vue, or Angular, cloud-native environments and CI/CD, and a track record of leading technical initiatives across teams.\nBenefits\nEquity: Highly competitive equity package designed for a foundational hire.\nHybrid Model: Expected ~3 days per week in-office - San Mateo, CA\nCompensation $178,000 - $223,000 base + equity + benefits\nBenefits\nThe Perks, Why Work On the MrBeast Team\nWe are redefining what entertainment and storytelling look like at global scale. Every piece of content we publish reaches millions and influences culture in real time. This is your opportunity to lead the team that decides how those moments come to life across every screen.\nCompetitive Salary\nGenerous Medical (Blue Cross Blue Shield), Dental, Vision and company-paid Life Insurance \nCompany contributions to employee Health Savings Accounts (HSA) \n401k Plan with Safe Harbor company-matching\nFlexible vacation policy and paid company holidays\nCompany-provided technology package \nRelocation assistance where applicable, including travel and company-provided housing for the first 90 days","description_format":"text","description_chars":4253,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["401k plan","Equity","Flexible vacation policy","Life insurance","Relocation assistance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Influencers","Content Creation"],"lifecycle":[{"event":"open","at":"2026-09-11T01:59:18Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 1","filings_12m":1,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":302500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.739,"p_room":0.44,"age_days":134,"expected_fill_days":101,"reasons":["conf:1","velocity","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":{"stated_usd_annual":223000,"is_top_pay":true},"html_url":"https://alion.io/job/mrbeastyoutube-senior-frontend-engineer","json_url":"https://alion.io/job/mrbeastyoutube-senior-frontend-engineer.json","meta":{"generated_at":"2026-10-31T01:13:29Z","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":1705,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":678220},"rest":"https://alion.io/mcp/rest/get_company?id=678220"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmrbeastyoutube-senior-frontend-engineer"},{"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%2Fmrbeastyoutube-senior-frontend-engineer"},{"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%2Fmrbeastyoutube-senior-frontend-engineer"},{"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/mrbeastyoutube-senior-frontend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmrbeastyoutube-senior-frontend-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":696139}},{"tool":"search_jobs","arguments":{"company":"mrbeastyoutube.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":696139},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
