We believe the tools of wealth creation have been locked behind institutional walls for too long. We are here to change that.\nWho you are:\nYou are a product engineer with 2-5 years of experience building snappy, intuitive user experiences at scale. Your expertise spans from designing high-quality and polished interfaces to implementing performant NextJS / React architectures that feel instant and delightful. You have strong opinions on how to achieve the perfect balance between aesthetics and functionality, ensuring every interaction drives user engagement and satisfaction.\nYou are deeply passionate about your craft and draw inspiration from products like Notion, Linear, and Cursor. You stay current with the latest developments in frontend technology and design patterns. You thrive in fast-paced environments where you can experiment, iterate, and push the boundaries of what's possible with modern web experiences. You don’t need a product designer to build an experience customers love, you empathize with the needs of the customer and carry your own design sense.\nKey Responsibilities:\nDesign and build a crisp, intuitive agent IDE that developers love to use\n\nImplement beautiful performance reporting dashboards with integrated charts, graphs, and key metrics\n\nDevelop an engaging onboarding flow that helps new users discover and adopt core features\n\nOptimize frontend performance through code splitting, caching strategies, and rendering optimizations\n\nCollaborate with product and engineering teams to translate user needs into elegant UI/UX solutions\n\nBuild reusable component libraries and design systems that scale across the product\n\nWhat We're Looking For:\nStrong software engineering fundamentals with deep expertise in React, Next.js, and TypeScript\n\nHands-on experience building production web applications with complex state management and real-time interactions\n\nProficiency with Tailwind CSS and component registries like Shadcn for rapid, consistent UI development\n\nEye for design with the ability to implement polished interfaces from mockups or create them from scratch\n\nKnowledge of modern CSS techniques, animation libraries, and responsive design patterns\n\nUnderstanding of frontend performance optimization, accessibility, and cross-browser compatibility\n\nAbility to balance innovation with pragmatism - shipping working solutions while pushing technical boundaries\n\nBonus:\nStrong interest in the stock market\n\nBackground building React Native products\n\nHas used Wall Street Bets or After Hours\n\nVantheon is a small team building something that actually matters. If you think the tools of wealth creation should be accessible to everyone, you’ll fit in here. We move fast, take ownership seriously, and hold each other to a high standard.\nWe take care of the people who build with us: 100% health insurance coverage (50% for dependents), unlimited PTO, a $2,000 annual AI learning stipend, 401k, and an on-site chef for those working out of the office.","description_format":"text","description_chars":3080,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["401k plan","Health insurance","Insurance coverage","Unlimited PTO"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial AI","AI Research Labs"],"lifecycle":[{"event":"open","at":"2026-11-11T01:17:50Z"}],"visa":[],"liveness":{"score":72,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.8,"p_room":0.9,"age_days":15,"expected_fill_days":23,"reasons":["conf:4","win:mid","comp:junior"],"computed_at":"2026-11-11T05:49:22Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/vantheon-founding-engineer-frontend-2","json_url":"https://alion.io/job/vantheon-founding-engineer-frontend-2.json","meta":{"generated_at":"2026-11-11T06:49:14Z","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":9984,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":4479783},"rest":"https://alion.io/mcp/rest/get_company?id=4479783"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvantheon-founding-engineer-frontend-2"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fvantheon-founding-engineer-frontend-2"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fvantheon-founding-engineer-frontend-2"},{"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/vantheon-founding-engineer-frontend-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvantheon-founding-engineer-frontend-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4049420}},{"tool":"search_jobs","arguments":{"company":"vantheon.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4049420},"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.
