Making that possible in a browser requires a 3D engine that can render tens of millions of points while supporting CAD-grade picking, clipping, snapping, and measurement. You'll work directly on that engine and the tools built on it.\nThis role is ideal for an early-career engineer with a strong foundation in 3D math who wants to work on a real production renderer, not a demo.\nYou'll do well here if you enjoy digging into difficult technical problems and building software that stays fast and reliable on large, messy real-world datasets. When the right approach isn't obvious, you'll research how others have solved similar problems, test your assumptions, and choose a practical solution. Our engineers are trusted to own their work and drive meaningful outcomes.\nWhere you will make an impact\nBuild 3D tools that surveyors use to inspect point clouds and create precise engineering drawings\n\nExtend our point-cloud renderer and GPU picking system\n\nSolve geometry problems behind clipping, snapping, construction planes, and camera controls\n\nFind and fix performance problems that appear with large real-world datasets\n\nImprove the shared rendering and interaction systems behind our CAD tools\n\nWhat you bring\nA strong foundation in 3D math and spatial reasoning, including transforms, planes, and projections\n\nExperience building software through coursework, personal projects, internships, or full-time work\n\nThe ability to read and change code you did not write\n\nAttention to correctness and performance\n\nSound judgment about when to refine a solution and when to ship it\n\nExperience with TypeScript and browser graphics, or comparable experience writing performance-sensitive graphics code in a statically typed language\n\nThe initiative to investigate problems, ask useful questions, and finish what you start\n\nBonus experience\nWebGL, GLSL, Three.js, Cesium, or another real-time graphics system\n\nPoint clouds, geospatial data, or large-coordinate rendering\n\nExperience applying geometry, spatial algorithms, or numerical methods to open-ended problems with noisy data and real-world tradeoffs\n\nCAD, mapping, visualization, robotics, or game-engine projects\n\nAbout Mach9\nMach9 is transforming civil infrastructure design with AI-powered geospatial tools. Our platform accelerates the creation of engineering deliverables from raw data, cutting manual drafting time by 96×. Trusted by global leaders in engineering and construction, we're backed by Y Combinator, Quiet Capital, and top founders and executives from Cruise, Autodesk, Adobe, and DoorDash.\nWe believe the needs of a startup benefit from an in-person culture. The team works out of our office in SoMa, with the flexibility to work from home when needed.","description_format":"text","description_chars":2888,"description_truncated":false,"requirements":{"experience_years_min":null,"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":["Sales & Marketing","Advertising"],"lifecycle":[{"event":"open","at":"2026-10-21T06:47:39Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":2,"expected_fill_days":31,"reasons":["conf:1","stale_co","velocity","win:early"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":180000,"is_top_pay":true},"html_url":"https://alion.io/job/mach9-software-engineer-3d-graphics","json_url":"https://alion.io/job/mach9-software-engineer-3d-graphics.json","meta":{"generated_at":"2026-10-24T01:11:49Z","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":1942,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":8667},"rest":"https://alion.io/mcp/rest/get_company?id=8667"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmach9-software-engineer-3d-graphics"},{"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%2Fmach9-software-engineer-3d-graphics"},{"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%2Fmach9-software-engineer-3d-graphics"},{"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/mach9-software-engineer-3d-graphics\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmach9-software-engineer-3d-graphics"}]}
