Its interdisciplinary team combines software, AI, science, design, and deep domain knowledge to tackle complex physical-world problems at scale.\nThe Opportunity\nThis is an opportunity to own one of the most technically challenging parts of an emerging product: making complex buildings, sites, geometries, and spatial information intuitive for users to understand and manipulate.\nYou will join early enough to shape both the engineering approach and how this capability appears in the product.\nThe Role\nYou will work as a Full Stack Engineer with particular depth in interactive 3D visualization. You'll build production software that brings complex building, site, and geospatial information together inside intuitive web experiences while contributing across the wider stack.\nWhat You’ll Do\nDesign and build production-grade software for visualizing and interacting with complex 3D building and site information.\n\nCreate performant, interactive experiences around complex geometries and hierarchical 3D data.\n\nDevelop web workflows combining building information with geospatial and other contextual data layers.\n\nOwn functionality across front-end and back-end systems.\n\nWork directly with users to understand requirements, collect feedback, and improve the product.\n\nPartner closely with software engineers, AI engineers, designers, scientists, and domain specialists.\n\nHelp define the technical and product direction for 3D capabilities as the platform evolves.\n\nWhat You’ll Bring\n3+ years of experience building substantial software systems and web applications.\n\nStrong Python and JavaScript/React development skills.\n\n1+ years of hands-on experience building interactive, real-time 3D experiences involving CAD, BIM, complex geometry, simulation, or comparable technologies.\n\nStrong software engineering and system design fundamentals.\n\nExperience owning meaningful product features from initial problem through production.\n\nComfort navigating ambiguity and contributing across multiple areas of a small engineering team.\n\nA product mindset and interest in building technology with tangible real-world impact.\n\nWhat This Role Requires\nStrong full stack software engineering capability.\n\nGenuine hands-on experience developing interactive 3D functionality, not solely static rendering or visualization work.\n\nAbility to build robust production web applications alongside specialist 3D functionality.\n\nWillingness to work across the stack rather than remaining within a narrow graphics or GIS speciality.\n\nWhy Join\nTake meaningful ownership of a sophisticated 3D product area while it is still being defined.\n\nApply technical skills to software connected directly to buildings, communities, sustainability, and the physical world.\n\nWork alongside a highly interdisciplinary technical team solving problems that sit across AI, engineering, spatial data, and the built environment.\n\nAbout People in AI\nPeople in AI is a specialist recruitment partner connecting exceptional AI, machine learning, data, and engineering talent with some of the most ambitious technology companies in the world. We work closely with founders, technical leaders, and hiring teams to represent opportunities accurately and help candidates assess genuine fit.","description_format":"text","description_chars":3550,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence"],"lifecycle":[{"event":"open","at":"2026-10-04T21:13:54Z"}],"visa":[],"liveness":{"score":17,"band":"cold","label":"Long shot","p_open":1,"p_active":0.317,"p_room":0.55,"age_days":20,"expected_fill_days":19,"reasons":["conf:3","agency","stale_co","velocity","win:tail"],"computed_at":"2026-10-12T06:55:09Z"},"pay":{"stated_usd_annual":225000,"is_top_pay":true},"html_url":"https://alion.io/job/people-in-ai-full-stack-engineer-ml-agentic-system","json_url":"https://alion.io/job/people-in-ai-full-stack-engineer-ml-agentic-system.json","meta":{"generated_at":"2026-10-12T09:11:35Z","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":13851,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":3862080},"rest":"https://alion.io/mcp/rest/get_company?id=3862080"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpeople-in-ai-full-stack-engineer-ml-agentic-system"},{"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%2Fpeople-in-ai-full-stack-engineer-ml-agentic-system"},{"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%2Fpeople-in-ai-full-stack-engineer-ml-agentic-system"},{"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/people-in-ai-full-stack-engineer-ml-agentic-system\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpeople-in-ai-full-stack-engineer-ml-agentic-system"}]}
