Within a few months of launch, we signed Fortune 500 companies. Within a year of founding, our customers, all $1B+ revenue enterprises, continue to grow in number and are actively championing us to their networks, and our marketing and CAC to get here has been $0.\nWe're hiring Software Engineers to help build the systems that make this possible. Our team comes from enterprise AI and manufacturing and has been shipping agents in production environments since the beginning. We need engineers who want to own what they build.\nCompany Highlights\nThe Team: Our CEO previously led and scaled three of Zoom's products past $300M in revenue, and our CTO is an ex-AI researcher who has spent his entire career in enterprise AI, leading engineering teams from seed through Series C. The broader team includes repeat VC-backed founders, Caltech PhDs, former quants, chess masters, Six Sigma Master Black Belts, and one very enthusiastic Bonsai grower.\n\nProduct: We pride ourselves on our depth of our experience building agents, and on our continued diligence in leveraging the latest technology. We hold a high bar of excellence that starts with the founding team.\n\nHypergrowth: 30x revenue growth in the first half of this year, with the majority of our pipeline coming from customer references.\n\nBackground\nDeploying truly impactful AI Agents today requires teams of forward-deployed engineers, months of ontology design, hundreds of ad-hoc integrations, and thousands of lines of glue code. It’s slow, expensive, brittle, and impossible to scale.\nFragment eliminates all of that. We’ve built a platform where:\nOntology Agents autonomously construct the context layer, unifying structured + unstructured data, capturing tribal knowledge, and composing it all into a real-time ontology of the business.\n\nSelf-assembling Process Agents automate workflows that would normally be manually and tediously handled by BPOs. Our first suite of agentic workflows, which drove our early traction, targets procurement.\n\nOur product sits in the #1 budget priority for traditional enterprises right now: AI that streamlines labor, and actually works in production.\nWhat You'll Do\nYou will design and own systems that don’t exist yet -- the foundational architecture for AI Agents operating over complex enterprise data. For example:\nBuild a distributed agent pipeline that processes tens of millions of data points with deterministic, auditable, and multi-tenant-safe behavior\n\nDefine and develop an automation editor that takes a visual-text hybrid approach to workflow development. Enable dynamic, configurable design that autonomously adapts to the processes of a customer.\n\nEngineer graph traversal + indexing systems enabling fast, lossless reasoning over our Unified Data Interface (UDI) and arbitrary data systems.\n\nDefine the core framework for self-assembling agents that compose and execute workflows autonomously -- safely, predictably, and with full traceability\n\nThis is not a “feature team” role. This is foundational engineering, shaping the platform that every agent and every enterprise workflow will rely on.\nWho You Are\nWe’re looking for a high-slope generalist with 3-7+ years of experience who gets restless when they're not building things that matter. You might describe yourself as someone who:\nLearns ridiculously fast\n\nThrives in ambiguity\n\nThinks in systems, not tickets\n\nShips high quality work quickly\n\nGets excited by messy enterprise data and hard problems\n\nWants to own architecture, product, and customer impact\n\nHas seen high quality production code across the stack\n\nInterested? Reach out even if you’re not sure you’re a perfect fit. High-slope engineers rarely fit cleanly on paper.","description_format":"text","description_chars":3794,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Transportation & Logistics","Supply Chain"],"lifecycle":[{"event":"open","at":"2026-11-01T07:35:00Z"}],"visa":[],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.723,"p_room":0.45,"age_days":41,"expected_fill_days":25,"reasons":["conf:2","urgency","win:tail"],"computed_at":"2026-11-02T06:13:15Z"},"pay":{"stated_usd_annual":350000,"is_top_pay":true},"html_url":"https://alion.io/job/fragment-software-engineer","json_url":"https://alion.io/job/fragment-software-engineer.json","meta":{"generated_at":"2026-11-02T14:04:56Z","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":19279,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":4491946},"rest":"https://alion.io/mcp/rest/get_company?id=4491946"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffragment-software-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%2Ffragment-software-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%2Ffragment-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/fragment-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffragment-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3584043}},{"tool":"search_jobs","arguments":{"company":"fragment.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3584043},"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.
