They're now hiring engineers who want to have a big impact on the product and take real ownership from day one.\nYou'll be joining a small, high-output engineering team where your work won't get lost in layers of process. You'll have the opportunity to take ideas from architecture → build → production and see the impact directly.\nIt's a fast-paced, high-intensity environment. They're looking for people who move quickly, take ownership and naturally go and build things.\nThe Role\nWe're looking for a Full Stack Engineer with a strong focus on AI.\nYou'll work across the stack from customer-facing product features to the AI agents powering them.\nYou'll own systems through architecture, development, deployment and production, working on challenging problems around AI agents, large-scale data and reliable production systems.\nThis is a hands-on role for someone who enjoys building rather than just maintaining existing systems.\nWhat We're Looking For\n3-7 years of software engineering experience\nStrong production experience with TypeScript, NestJS and React\nExperience deploying and operating applications on AWS\nHas built and shipped AI agents into production\nStrong understanding of system design and production engineering\nHas owned features from architecture through deployment\nComfortable debugging and resolving real production issues\nStrong software engineering fundamentals\nBonus Points\nExperience building LLM evaluation frameworks\nExperience with feedback loops or self-improving AI systems\nExperience working with large datasets\nTerraform / infrastructure-as-code experience\nStrong observability experience\nExperience with Cursor, Claude Code, Copilot or similar\nThe Type of Engineer We're Looking For\nWe're particularly interested in high-agency builders who:\nHave built products outside of work\nHave shipped side projects or open-source work\nHave taken an idea from 0 → 1\nHave identified a problem and solved it without being asked\nMoves quickly and learns quickly\nBrings ideas to the team rather than waiting for instructions\nWe're not looking for someone who just executes tickets.\nWe want engineers who see something, take ownership and go build it.","description_format":"text","description_chars":2483,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence"],"lifecycle":[{"event":"open","at":"2026-10-19T18:32:41Z"}],"visa":[],"liveness":{"score":54,"band":"ok","label":"Likely open","p_open":1,"p_active":0.542,"p_room":1,"age_days":1,"expected_fill_days":112,"reasons":["conf:9","agency","velocity","win:early"],"computed_at":"2026-10-21T05:46:15Z"},"pay":{"stated_usd_annual":270000,"is_top_pay":true},"html_url":"https://alion.io/job/umatr-full-stack-engineer-ai","json_url":"https://alion.io/job/umatr-full-stack-engineer-ai.json","meta":{"generated_at":"2026-10-21T17:35:56Z","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":24811,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":2053453},"rest":"https://alion.io/mcp/rest/get_company?id=2053453"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fumatr-full-stack-engineer-ai"},{"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%2Fumatr-full-stack-engineer-ai"},{"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%2Fumatr-full-stack-engineer-ai"},{"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/umatr-full-stack-engineer-ai\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fumatr-full-stack-engineer-ai"}]}
