Existing tools depend on humans to manually update records, push projects forward, and make sure important work doesn't fall through the cracks.\nWe believe AI should do more.\nThorin is building proactive, long-horizon AI agents that continuously understand what is happening across an organization and help teams execute over weeks, months, and years. Rather than waiting for prompts, Thorin develops a living understanding of how a business actually operates.\nBorn out of 8VC's Build program and backed by one of Silicon Valley's strongest venture ecosystems, Thorin is building the operating system for the AI-native enterprise.\nWhat You’ll Do\nOwn major technical initiatives from ambiguous customer/product problem to architecture, implementation, iteration, and production quality.\n\nBuild AI-native product systems involving LLMs, agents, evals, retrieval, enterprise context, and workflow automation.\n\nLead by building: set technical direction, make tradeoffs explicit, review work, unblock others, and raise the quality of a small engineering pod.\n\nTurn product and customer signal into clear technical plans without waiting for perfect requirements.\n\nWhat We’re Looking For\nStaff-level engineering judgment, whether or not your current title says Staff.\n\nStrong hands-on coding ability and architectural taste across production systems, AI applications, infrastructure, agents, or product engineering.\n\nHigh slope: you have progressed quickly, taken on harder problems, and become someone others trust with ambiguous technical work.\n\nAI-native instincts: you actively use and build with AI systems and understand where they work, fail, and create new product possibilities.\n\nProduct judgment: you connect technical choices to user value, customer deployment, product credibility, and business priorities.\n\nLow ego, high standards, and comfort operating before the roadmap is obvious.\n\nIn Your First 30 Days, You Will\nOwn and ship meaningful production work.\n\nCreate clarity around a major technical lane or pod.\n\nReduce a roadmap or execution bottleneck without adding management overhead.\n\nBenefits\nCompetitive compensation and meaningful early equity.\n\nMedical, dental, and vision coverage.\n\nDaily meal support while working with the team.\n\nUnlimited access to frontier AI coding tools.\n\nDirect exposure to founders, investors, design partners, and early customers.\n\nLocation\nThis is an in-person role based in San Francisco. At this stage, we believe the best work happens through high-bandwidth collaboration, fast feedback loops, and shared context with the team.\nCompensation\nThe expected base salary range for this role is $250,000-$350,000, plus equity and benefits. Actual compensation will be determined based on experience, skill level, and scope.","description_format":"text","description_chars":2980,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence"],"lifecycle":[{"event":"open","at":"2026-10-14T23:13:40Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.306,"p_room":0.28,"age_days":128,"expected_fill_days":28,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":{"stated_usd_annual":350000,"is_top_pay":true},"html_url":"https://alion.io/job/thorin-founding-senior-ai-product-engineer","json_url":"https://alion.io/job/thorin-founding-senior-ai-product-engineer.json","meta":{"generated_at":"2026-11-01T00:19:10Z","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":598,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":3781471},"rest":"https://alion.io/mcp/rest/get_company?id=3781471"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fthorin-founding-senior-ai-product-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%2Fthorin-founding-senior-ai-product-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%2Fthorin-founding-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/thorin-founding-senior-ai-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fthorin-founding-senior-ai-product-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":2572266}},{"tool":"search_jobs","arguments":{"company":"thorin.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":2572266},"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.
