We're looking for an AI Engineer to own and architect the intelligence layer: the prompts and guardrails that shape agent behavior, and the canonical data model and knowledge graph those agents - and our separate Data Science team's models - reason over.\nThis role sits closer to architecture than a typical AI engineering position - you're not just implementing against a schema someone hands you, you're deciding what that schema should be.\nWhat you'll do\nArchitecture & knowledge modeling:\nOwn architectural decisions for how intelligence - prompts, retrieval, and agent logic - plugs into our platform's core: where inference happens, how data flows through our workflow orchestration layer, and when a capability belongs in the ontology layer versus a prompt versus the Data Science team's remit.\nDefine and evolve the canonical data model - the shared representation of core business entities that every agent, workflow, and downstream model has to agree on, sitting on top of our platform's versioning and governance framework.\nDesign automated ontology creation - turning raw source schemas from enterprise systems into structured entities, relationships, and synonyms programmatically, so a new data source onboards without hand-curated mapping every time.\nBuild and maintain the knowledge graph connecting the core entities in our domain - the structure our product's retrieval and agent logic reasons over, and the foundation the Data Science team builds its models on top of.\nAgent intelligence:\nDesign and iterate on agent personas, system prompts, and guardrail logic - role/policy/content-safety checks, autonomy thresholds, and escalation rules.\nOwn the evaluation harness: golden tests and prompt-regression checks that catch quality drift before an agent version ships.\nValidate agent behavior across test and production model configurations, working with our internal model registry.\nTune retrieval quality for knowledge-grounded agents - chunking strategy, relevance testing, and search infrastructure tuning.\nHow you'll work:\nBuild against written specs (spec → plan → tasks) rather than open-ended tickets, and write the specs yourself for the architecture and agent-intelligence surface you own.\nUse AI coding assistants as your primary implementation tool for scaffolding and iteration - your judgment goes into what to build and whether the output is actually correct, not into typing every line by hand.\nReview your own AI-assisted output as rigorously as you'd review a teammate's PR; verification is part of the job, not a step you skip because the code compiled.\nPartner closely with the Data Science team as a consumer of your canonical data model and knowledge graph - you own the structure, they own what gets modeled on top of it.\nWhat we're looking for:\nExperience making architectural calls on a data or AI platform - not just implementing someone else's design.\nHands-on experience with ontology design, knowledge graphs, or semantic/canonical data modeling - you've built one of these, not just read about them.\nHands-on experience with LLM-based systems: prompt design, retrieval-augmented generation, and evaluating generative output quality.\nStrong Python fundamentals and comfort working against a modern backend service and its data model.\nFamiliarity with agentic or workflow-orchestration patterns - multi-step graphs, tool-calling, trigger → retrieve → act → respond pipelines.\nComfortable pair-programming with AI coding assistants as a primary tool, balanced with strong code-review instincts.\nClear technical writing - specs are this role's primary interface with the rest of the team.\nNice to have:\nCPG / Retail / Supply chain domain knowledge","description_format":"text","description_chars":3897,"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":[],"lifecycle":[{"event":"open","at":"2026-10-17T15:35:14Z"}],"visa":[],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":1,"p_active":0.5,"p_room":0.45,"age_days":39,"expected_fill_days":22,"reasons":["conf:1","win:tail"],"computed_at":"2026-10-17T23:58:42Z"},"pay":null,"html_url":"https://alion.io/job/syrencloud-ai-engineer-knowledge-graphontology","json_url":"https://alion.io/job/syrencloud-ai-engineer-knowledge-graphontology.json","meta":{"generated_at":"2026-10-17T23:58:42Z","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":2386,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":4442673},"rest":"https://alion.io/mcp/rest/get_company?id=4442673"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsyrencloud-ai-engineer-knowledge-graphontology"},{"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%2Fsyrencloud-ai-engineer-knowledge-graphontology"},{"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%2Fsyrencloud-ai-engineer-knowledge-graphontology"},{"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/syrencloud-ai-engineer-knowledge-graphontology\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsyrencloud-ai-engineer-knowledge-graphontology"}]}
