We're backed by some of the best investors in Silicon Valley, including Y Combinator, Base10, Transpose Platform, and others, to reinvent the way that legal solutions are delivered for Startups.\nWe support companies across their lifecycle, including complex formations, fundraising and priced rounds, commercial contracting, hiring and team changes, mergers and acquisitions, and dissolutions. VectorAI powers agentic data rooms, proprietary draft/review/negotiate tools, e-signatures, cap table management, legal health checks and more.\nOur goal is to make high-quality legal work faster, more scalable, and more cost-efficient.\nAbout the RoleWe’re hiring an AI Engineer to design, build, and deploy production-grade LLM systems that power our legal platform. This role is focused on applied AI, turning real-world legal workflows into reliable, agent-driven systems that operate over documents, messages, and structured data.\nYou’ll work at the core of our AI layer, building agents, evaluation systems, and data pipelines that directly impact how legal work is performed. The environment is highly iterative and performance-driven, with a strong emphasis on reliability, correctness, and real-world usability, not just demos.\nWhat You’ll Do\nDesign and deploy LLM-powered systems for document understanding, drafting, and workflow automation\n\nBuild and orchestrate agent-based systems (e.g., LangChain / Deep Agents) for complex, multi-step tasks\n\nDevelop and maintain evaluation frameworks to measure accuracy, reliability, and regressions\n\nImplement data pipelines for ingesting and structuring documents (including OCR workflows)\n\nImprove system performance through prompt design, retrieval strategies, and tool integration\n\nWork closely with product and engineering to translate legal workflows into AI-native systems\n\nDebug and optimize long-running agent jobs and failure modes in production\n\nContribute to overall AI architecture, including memory, context management, and retrieval layers\n\nQualifications\n3–7 years of engineering experience, or a strong track record building and shipping AI systems (excluding internships)\n\nProficiency in TypeScript and experience building production backend systems\n\nHands-on experience with LLM frameworks (e.g., LangChain) and agent architectures\n\nExperience designing and running evals (benchmarks, test sets, regression tracking)\n\nFamiliarity with document processing pipelines, including OCR and unstructured data extraction\n\nStrong understanding of prompt engineering, retrieval (RAG), and tool-augmented generation\n\nAbility to operate in ambiguous, fast-moving environments and own systems end-to-end\n\nStartup or high-velocity experience preferred\n\nOriginally posted on Himalayas","description_format":"text","description_chars":2882,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-12T17:31:30Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.858,"p_room":1,"age_days":4,"expected_fill_days":28,"reasons":["seen:4","win:early"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":180000,"is_top_pay":false},"html_url":"https://alion.io/job/vector-systems-founding-ai-engineer","json_url":"https://alion.io/job/vector-systems-founding-ai-engineer.json","meta":{"generated_at":"2026-10-17T09:27:40Z","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":12515,"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":4422258},"rest":"https://alion.io/mcp/rest/get_company?id=4422258"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvector-systems-founding-ai-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%2Fvector-systems-founding-ai-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%2Fvector-systems-founding-ai-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/vector-systems-founding-ai-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvector-systems-founding-ai-engineer"}]}
