Work that used to take teams of lawyers weeks now happens in minutes. YC S24, founded by a former M&A attorney from Kirkland & Ellis and Gunderson Dettmer.\nWe're hiring a design engineer to own how the product looks, feels, and works. You'll design features in Figma, then build them yourself in our React codebase. No handoffs.\nWhat You'll Do\nDesign and build features end-to-end: From Figma concepts to production React components. No handoffs, no waiting, you ship the whole thing.\nOwn the design system: We have a component library built on Radix UI, Tailwind CSS, and tailwind-variants. You'll evolve it as the product grows.\nSolve hard UX problems: How do you display 500 extracted provisions across 200 contracts in a way that's actually usable? How do you make an AI-powered document review feel trustworthy? These are the kinds of problems you'll tackle daily.\nObsess over details: Micro-interactions, loading states, keyboard shortcuts, error messages. The small things that separate \"functional\" from \"delightful.\"\nTalk to users: Our users are M&A attorneys. You'll watch them use the product, understand their workflows, and design for how they actually work, not how you think they should.\nThe UX challenges are hard. Attorneys review hundreds of contracts with thousands of extracted provisions. Making that feel simple and trustworthy is the job.\nStack\nNext.js 16, React 19, TypeScript, Tailwind CSS, Radix UI, TanStack (Query + Table), Motion, dnd-kit, Liveblocks, Figma\nYou\nYou design and build - Figma to production React, no gap in between\nYou've shipped real product UI, not just component libraries\nYou think in systems and care about consistency across an entire app\nYou make complex, data-heavy interfaces feel simple\nYou notice the details: loading states, error messages, transitions, empty states\nStrong with Tailwind CSS and component architecture\nCompensation\n$100K-$150K + 1.50% founding equity\nSan Francisco, in person.\nIntro call (30 min) - Meet the founders, learn about Mage\nPortfolio review (30 min) - Walk us through projects you've designed and built\nTake-home: design + build (~4 hrs) - Design and implement a small feature based on a real product prompt\nIn-person trial - Work with us for a week in SF on a real problem\nOffer","description_format":"text","description_chars":2317,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Document AI","Legal AI"],"lifecycle":[{"event":"open","at":"2026-09-25T17:16:15Z"}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":43,"reasons":["conf:0","win:early"],"computed_at":"2026-09-26T05:45:00Z"},"pay":{"stated_usd_annual":150000,"is_top_pay":true},"html_url":"https://alion.io/job/mage-legal-founding-design-engineer","json_url":"https://alion.io/job/mage-legal-founding-design-engineer.json","meta":{"generated_at":"2026-09-27T03:01:01Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2762,"day_limit":5000,"remaining_today":2238,"minute_limit":60,"resets_at":"2026-09-28T00:00:00Z"}}}
