That means scoping problems with customers and product, prototyping fast, and taking what works from POC to production on some of the world's largest websites.\n\nWhat we're looking for\n5- 9 years building backend or product systems, mainly in Python (Django or FastAPI) with Postgres.\nAt least 1.5 years shipping LLM or agent-based features to real users in production, not just demos.\nHands-on experience with agent frameworks, RAG, tool-calling, structured outputs and prompt iteration driven by evals.\nComfort with ambiguity: you turn a loosely defined problem into shipped software and use production data to decide what to improve.\nProduct-company or startup experience, with clear ownership of what you built.\nNice to have\nPersonalization, experimentation, CRO or martech experience.\nWorkflow orchestration (Temporal or similar), LLM gateways or observability tools, Kubernetes or GCP.\nExperience working directly with enterprise customers.\nWhy Fibr\nHelp define a new category, agent readiness, while it's being built.\nHigh ownership in a small team: what you ship goes live for global brands and banks.\nWork directly with the founders.","description_format":"text","description_chars":2282,"description_truncated":false,"requirements":{"experience_years_min":5,"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":["Optical Communications","Optics & Photonic Components","Electrical Equipment & Cables"],"lifecycle":[{"event":"open","at":"2026-11-11T20:09:00Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":30,"reasons":["seen:2","win:early"],"computed_at":"2026-11-14T05:58:10Z"},"pay":null,"html_url":"https://alion.io/job/fibrain-senior-ai-product-engineer","json_url":"https://alion.io/job/fibrain-senior-ai-product-engineer.json","meta":{"generated_at":"2026-11-14T15:56:39Z","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":17907,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":53554},"rest":"https://alion.io/mcp/rest/get_company?id=53554"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffibrain-senior-ai-product-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Ffibrain-senior-ai-product-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Ffibrain-senior-ai-product-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/fibrain-senior-ai-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffibrain-senior-ai-product-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4091381}},{"tool":"search_jobs","arguments":{"company":"fibrain.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4091381},"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.
