Be the new kid at a boarding school and get everyone to fall for you, or plan a jailbreak with Sherlock Holmes. Every text you send changes the plot and how characters feel about you, so no two playthroughs are the same.\nOur mission at Y/n is to create the most entertaining storyteller in the world, and give it to everyone.\nWhy you should join us\nPeople love Y/n:Users spend on average 3+ hours playing Y/n everyday\nWe are top #10 books apps in the world (reached #4 app in the App Store last month), even though we just launched\nWe raised $14M from top VCs\n\nWe work on interesting technical problems:We serve ~3T tokens (~300M user messages, growing 40% MoM) per month with a team of 4\nWe manage a LOT of compute!\nTraining an AI to be fun and creative is incredibly interesting\n\nThe founders + team are fun to work with:My co-founder Eric trained the first-ever image editing AI in the world\nBefore Y/n, I was the founding designer and one of the first employees at Substack, where I learned a lot about product and media\nTogether, we previously co-founded Can of Soup, a hit AI image sharing app, which you can read about in the New York Times\n\nSome examples of what you would do\nYou'd be one of our first engineers, with real ownership across the product and the infrastructure. In practice that could mean:\nBuilding our personalized recommendation system infrastructure\nBuilding features in our mobile and web application\nThe role will adapt and grow as we do, so don’t worry if you haven’t worked on recommender systems or ML yet!\nWhat we’re looking for\nYou’ve built actual infrastructure (not just pushed to Vercel)\nYou’ve worked at a startup or built meaningful side projects\nOptional: you’re into fandom, reading, games, or fanfiction!\nYou're willing to relocate to San Francisco. If you do not have US work authorization, we can help with that\nSend us your Github\n30 min interview with Gabriel (CEO)\nTechnical with Eric (CTO)\nPossible take-home or work trial\nOffer","description_format":"text","description_chars":2105,"description_truncated":false,"requirements":{"experience_years_min":1,"management_years_min":null,"team_size_min":4,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Books","Content Creation","Hobbies & Leisure"],"lifecycle":[{"event":"open","at":"2026-08-28T01:05:09Z"}],"visa":[],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.444,"p_room":0.28,"age_days":54,"expected_fill_days":24,"reasons":["conf:1","win:tail","crowd:junior"],"computed_at":"2026-10-21T05:46:15Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/yn-software-engineer","json_url":"https://alion.io/job/yn-software-engineer.json","meta":{"generated_at":"2026-10-22T03:41:21Z","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":3625,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":1376},"rest":"https://alion.io/mcp/rest/get_company?id=1376"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fyn-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%2Fyn-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%2Fyn-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/yn-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fyn-software-engineer"}]}
