We automate cross-document conflict detection across the complex, multi-party workflows that define how data centers and large commercial projects are designed and built. We recently closed our Series A led by Innovation Endeavors and are in active enterprise deployments with some of the largest GCs and data center builders in the country.\nWe move fast, we care about leverage, and we build with AI. We do this not just for our customers, but internally too. You’ll find a hard working team that will give you an incredible opportunity to quickly grow in your career.\nThe Role\nObjective: Be one of the strongest hands-on engineers on LightTable's lean, AI-native team. Own technical judgment, design, and delivery for a feature area, and help the platform expand from drawing review into new pre-construction workflows without a rewrite. This role is about building, not managing.\nOperating Model\nShip complete features end to end inside your pod, across AI, web, backend, and infrastructure, on a schedule the business can plan around\n\nWrite and review code every day: design reviews, architectural tradeoffs, and the quality bar inside your feature area are yours\n\nPartner with the CTO, the architecture tech lead, and the pod leads on shared architecture, clean interfaces between feature areas, and no duplicated work\n\nWork side by side with in-house domain experts, design partners, and customers (pre-construction teams, general contractors, and data center builders)\n\nBuild with AI coding tools aggressively but thoughtfully, and share with the team where tools like Claude Code and Codex genuinely make it faster\n\nWhat You’ll Do\nOwn Complete Features End to End\nTake features from ambiguous problem to production across a React frontend, a Python (FastAPI) backend, and LLM pipelines\n\nHold a consistently high engineering bar through code review and design review, and mentor senior engineers by example\n\nWork in a senior, lean team by design: small pods of senior and staff-level engineers where everyone does hands-on work every day\n\nOwn Technical Decisions in Your Feature Area\nOwn design reviews, architectural tradeoffs, and code quality across a React frontend and a Python (FastAPI) backend\n\nWork across a best-tool-for-the-job stack that includes Railway, Clerk, Supabase, S3, Modal, and Grafana, with no lock-in to a single cloud provider\n\nTranslate architecture direction into designs, scope, and sequencing you and your pod can execute\n\nMake AI Output Reliable\nBuild and debug agentic LLM workflows (Pydantic AI for orchestration and provider abstraction) that find real coordination issues\n\nThink like an ML engineer about why a model output is wrong and how to fix it: evaluation, data, and feedback loops with in-house domain experts\n\nKeep quality high as review volume grows, including personalized prioritization that learns from how each customer ranks issues\n\nSolve Hard Document Understanding Problems\nTurn high-resolution drawing sets into structured understanding\n\nTriangulate across dozens of document types: drawings, contracts, specifications thousands of pages long, purchase orders, Gantt charts, and field data\n\nRun long, fan-out-heavy jobs efficiently: a single drawing set upload can drive thousands of $’s of API calls and compute over many hours\n\nScale the Platform\nBuild the platform foundations that let engineering grow from about ten people toward 15-20 within a year without slowing down\n\nRaise the technical bar for the team through architecture proposals, reusable patterns, and pragmatic tooling\n\nPrepare the platform for new workflows such as estimating, value engineering, and permitting, and later construction and operations\n\nWhat We’re Looking For\nWe're looking for a hands-on senior engineer who is a builder first: strong product sense and real technical depth, comfortable blurring the lines between engineer, product manager, and designer. Strong computer science fundamentals and fluency in data science and machine learning matter, because many of LightTable's hardest problems are data science problems at heart. The north-star profile is a senior or staff-level engineer (roughly L6) who has owned large systems, set technical direction, and mentored senior engineers, while still shipping every day.\nMust-Have Experience\n10+ years coding professionally, with deep hands-on ownership of production systems\n\nSenior staff-level technical depth (roughly P6/L6): you have owned large systems and set technical direction as an individual contributor\n\nStartup experience where the lines between code, data, product, and design blur, and comfort operating in that overlap\n\nStrong computer science fundamentals and fluency in data science and machine learning concepts (for example, overfitting and experiment design)\n\nComfort building with LLMs: you have shipped something real on top of them, or you are clearly hungry to\n\nStrong experience with modern React and Python (FastAPI), or comparable full-stack depth you can transfer quickly\n\nDaily, forward-thinking use of AI coding tools such as Claude Code or OpenAI Codex, with nuance about where they help and where they carry risk\n\nProduct thinking and some design sense: you care what the customer touches, and you believe great engineering requires product thinking\n\nA consistently high bar for code quality and design, and comfort giving direct technical feedback in reviews\n\nDeep technical curiosity that has led to expertise across an atypically broad range of topics\n\nBuilder mentality in a fast-moving startup: comfort with ambiguity, multiple hats, and an org chart that will keep changing\n\nBased in the Denver Metro area (Boulder works) and in the downtown Denver office Monday, Wednesday, and Thursday.\n\nNice-to-Have Experience\nPast work as a startup founder, CTO, or CPO (a big plus)\n\nExperience as a founding or early engineer at an early-stage startup\n\nExperience with data infrastructure, ML/AI tooling, or AI evaluation systems\n\nExperience with agentic AI systems, computer vision, or document understanding in production\n\nExperience with high-resolution image processing or long-running, fan-out-heavy pipelines\n\nWhy Join LightTable AI?\nWe think LightTable is legitimately and objectively the most exciting AI startup in Colorado, and we would like you to come pressure-test that.\n\nShape the engineering org at the moment it forms. You are one of the first two pod leaders, not the tenth manager in an existing system.\n\nWork with a CTO who is staying deeply technical, so your judgment is engaged rather than overruled.\n\nBuild an AI-first product alongside domain experts in architecture and construction.\n\nGround-floor opportunity with meaningful equity in a fast-growing company.\n\nReal impact: we are building fast and partnering with some of the largest developers and contractors in the country.","description_format":"text","description_chars":7015,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Construction Management Software"],"lifecycle":[{"event":"open","at":"2026-11-12T01:56:42Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":40,"reasons":["conf:1","win:early"],"computed_at":"2026-11-12T03:55:11Z"},"pay":{"stated_usd_annual":260000,"is_top_pay":true},"html_url":"https://alion.io/job/lighttable-staff-software-engineer","json_url":"https://alion.io/job/lighttable-staff-software-engineer.json","meta":{"generated_at":"2026-11-12T03:55:11Z","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":8548,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"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":3782446},"rest":"https://alion.io/mcp/rest/get_company?id=3782446"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flighttable-staff-software-engineer"},{"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%2Flighttable-staff-software-engineer"},{"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%2Flighttable-staff-software-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/lighttable-staff-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flighttable-staff-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4128745}},{"tool":"search_jobs","arguments":{"company":"lighttable.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4128745},"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.
