We are not a task marketplace.\nWe are a consumer application where people upload their real photos, videos, and documents and get paid continuously.\nWe then filter, standardize, and license that data to frontier AI labs and enterprises that need fresh, rights-aware training data.\nSince launching our mobile app in 2026, we have:\nReached #1 on the App Store (Finance) with 0 paid marketing\nScaled to 600,000+ active data contributors\nProcessed 5M uploads per day\nRaised $15M+ from investors behind SpaceX, Airbnb, Coinbase, xAI, OpenAI, Anthropic, Spotify, Lyft, Uber, and more\nOur mission is to let anyone download the app and earn a real living wage from uploading their data.\nABOUT THE ROLE\nML Engineer - Fraud Detection & Data Quality\nEvery day, millions of files hit our system.\nYour job is to make sure only authentic, high-signal, human data gets through.\nYou’ll build:\nAI-generated image & video detection\nReverse image search & internet plagiarism rejection\nDuplicate fingerprinting (vector + perceptual hashing)\nCopyright risk detection\nEXIF / metadata tampering detection\nFraud network & device clustering systems\nHuman-in-the-loop verification pipelines\nThis is adversarial ML at scale, not academic benchmarks.\nExample:\nA user is tasked with uploading a video of themselves taking out the trash. The user uploads a video of their dog. The upload is rejected automatically.\nBut more complex. More requirements. At scale.\nWE’RE LOOKING FOR\n3+ years in computer vision / ML (PyTorch or TensorFlow)\nProduction ML deployment experience\nStrong SQL / PostgreSQL skills\nExperience with vector search (FAISS, pgvector, Pinecone)\nImage processing (OpenCV, PIL)\nComfort shipping backend systems (TypeScript/Deno or similar)\nBonus:\nDeepfake detection\nReverse image search systems\nCopyright detection pipelines\nTrust & Safety infrastructure\nCURRENT STACK\nBackend\nPostgreSQL (Supabase) - 100’s of millions of media files\nS3 storage\nDeno / TypeScript edge functions\nPython detection pipelines\nFrontend\nSwiftUI (migrating to Flutter)\nInternal verification tooling\nCOMPENSATION\nBase salary: $150,000 - $250,000\n$750,000 - $1,500,000 equity\nWe move fast and work hard.\nIf you're excited to build large-scale adversarial ML systems that sit at the core of next-gen AI data infrastructure, let’s talk.\nGROWTH OPPORTUNITY\nYou’ll join a team operating at the frontier of applied AI data infrastructure.\nIn this role, you’ll have the opportunity to:\nOwn core systems that power one of the largest human data networks in the world\nDesign infrastructure that directly influences what data trains next-generation AI models\nBuild at real scale - millions of uploads per day, adversarial environments, global contributors\nShip alongside a team that has built marketplaces, AI systems, and products used by millions\nIf you’re excited to move fast, build systems that matter, and help define how human data powers frontier AI, let’s talk.","description_format":"text","description_chars":3029,"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":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Data Providers & Datasets","AI Training Data & Annotation"],"lifecycle":[{"event":"open","at":"2026-09-13T00:14:21Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.175,"p_room":0.28,"age_days":261,"expected_fill_days":27,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-11-06T05:58:05Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/kled-fraudml-engineer","json_url":"https://alion.io/job/kled-fraudml-engineer.json","meta":{"generated_at":"2026-11-06T16:15:37Z","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":30206,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":680114},"rest":"https://alion.io/mcp/rest/get_company?id=680114"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkled-fraudml-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%2Fkled-fraudml-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%2Fkled-fraudml-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/kled-fraudml-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkled-fraudml-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":845097}},{"tool":"search_jobs","arguments":{"company":"kled.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":845097},"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.
