We power the next generation of AI-native law firms with one unified global brand, a proprietary technology platform, and a centralized back office - enabling lawyers to eliminate the administrative burden and focus on delivering exceptional outcomes for their clients. Manifest OS has raised a $60M Series A from Menlo Ventures, Kleiner Perkins, First Round, and Quiet Capital.\nAbout the Role\nWe're looking for a Design Engineer to help build the legal tech platform powering the next generation of AI-native law firms. You care as much about how software feels as how it works. You'll own the development of secure client portals and enterprise-grade systems - from architecture to production.\nThis opportunity is ideal for engineers who want broad scope, high ownership and move nimbly across lanes. You'll work across AI systems architecture and full-stack engineering - eval systems, retrieval, agent orchestration, and optimization, alongside the APIs, data models, and systems that power the core platform.\nThis is an in-person role - you'll be on-site at our NYC office 5 days a week.\nWhat You’ll Do\nDesign System Engineering\nEvolve the design system into scalable components and tokens that make every project fast to ship and beautiful by default, whether a person or an agent is building it.\n\nSpot patterns that keep recurring across the platform, and promote them into tested, documented primitives that designers and engineers can compose without reinventing.\n\nBuild the guardrails that keep the product on-system as it scales, including token linting, visual regression testing, and component documentation that AI coding tools can read and follow.\n\nFrontend Architecture\nTranslate the design system into components and tokens that make the next screen fast to ship and beautiful by default, by a person or an agent\n\nPartner with design on what AI-native interfaces should be in a high-stakes domain: progressive disclosure, streaming states, and the patterns nobody's figured out yet\n\nDefine the contracts between backend and UI - data fetching, caching, state boundaries, the choices that make the design hold up against real data\n\nOwn the screens clients and attorneys live in, where a well-set page turns a dreaded process into one that actually feels good to use\n\nBuild loading, empty, error, partial, and permission-restricted states as first-class parts of every feature, so nothing ships with only the happy path.\n\nTreat accessibility, performance, and failure recovery as acceptance criteria, not polish. A failed document upload the night before a filing deadline should tell the user exactly what happened and what to do next.\n\nProduct Engineering\nOwn end-to-end features across our legal tech platform - client portals, case management, and the workflows lawyers and clients depend on daily\n\nDesign production-grade APIs, data models, and permission systems for a regulated, high-trust domain\n\nAgent Platform\nEval systems, retrieval, and agent orchestration - building the infrastructure that measures and improves how our AI agents perform\n\nHarness engineering - building the tooling and guardrails that let the rest of the company build securely, reliably, and self-serve\n\nWhat We're Looking For\nMust-haves:\n7+ years building production software, with demonstrated depth in at least one area (backend systems, infra, ML/AI systems, frontend or similar)\n\nBuilt or meaningfully shaped a production design system, including component APIs, tokens, theming, and documentation, that other engineers adopted and shipped with\n\nProven track record delivering features that produce measurable business outcomes\n\nComfort with relational database design and data modeling\n\nHands-on experience deploying and operating services on a major cloud platform\n\nFluent with AI coding tools as a core part of your daily workflow\n\nA track record of self-teaching your way into unfamiliar systems and shipping there\n\nFirst-principles and systems thinking: you can reason about a system you didn't build, from the database up through the API to the product surface\n\nFamiliarity with our stack - TypeScript, React, GCP, PostgreSQL\n\nNice-to-haves:\nExperience making a design system legible to AI coding tools, through machine-readable documentation, token linting, or visual regression testing that keeps generated UI on-system\n\nDeeply engaged with the AI tooling ecosystem - you follow new model releases, experiment with new tools as they land, and stay current out of genuine curiosity\n\nExperience with eval systems, retrieval, agent orchestration OR ML in production\n\nBackground building client portals, CRMs, or case management systems\n\nFamiliarity with legal tech or other regulated industries\n\nThis is for you if....\nYou treat AI tools as core to how you architect and ship software. You have real depth in at least one area, plus the self-teaching ability to pick up unfamiliar systems and contribute there competently. You move with speed, thrive with ownership, and prefer outcomes over process. You want to build infrastructure that makes legal services more accessible to people.\n This is not for you if....\nYou do your best work with clear processes and defined guardrails already in place. You're earlier in your journey with AI-augmented development and want more time to build that muscle first.","description_format":"text","description_chars":5485,"description_truncated":false,"requirements":{"experience_years_min":7,"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":["Commerce","Professional Services","Legal Services"],"lifecycle":[{"event":"open","at":"2026-10-06T22:01:38Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":40,"reasons":["conf:0","win:early"],"computed_at":"2026-10-08T05:49:30Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/manifest-os-design-engineer","json_url":"https://alion.io/job/manifest-os-design-engineer.json","meta":{"generated_at":"2026-10-09T04:15:41Z","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","counted_by":"address","units_charged":1,"used_today":3809,"day_limit":5000,"remaining_today":1191,"minute_limit":60,"resets_at":"2026-10-10T00:00:00Z"}},"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":1994964},"rest":"https://alion.io/mcp/rest/get_company?id=1994964"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmanifest-os-design-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%2Fmanifest-os-design-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%2Fmanifest-os-design-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/manifest-os-design-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmanifest-os-design-engineer"}]}
