Unlike traditional LLM companies, Yobi builds foundation models of human behavior grounded in real-world actions such as purchases and store visits.\nOur private-by-design modeling enables state-of-the-art personalization and decisioning for leading brands and agencies while protecting privacy, safety, and ethics.\nToday, we are focused on bringing the performance of closed-web user acquisition to the open web and connected TV, giving brands walled-garden results without the walls.\nAt our core, Yobi is building the behavioral intelligence layer for any system that makes a personalization decision.\nWorking at Yobi\nWe’re at an inflection point-customer adoption is accelerating, but there’s still room to shape the architecture and culture from the ground up. Engineers here own major surface areas, build 0→1 systems in large-scale data and model infrastructure, and help define how Behavioral AI scales ethically and effectively.\nHighlights:\nPartnerships with Microsoft and Databricks\n\nFully remote or hybrid from several hubs (SF Bay Area, Seattle, NYC)\n\nWorld-class team of Machine Learning experts who worked on cutting edge infra and recommender systems @ Amazon, Uber, Twitter, Meta, etc.\n\nProduct and Go-To-Market teams who have taken ideas from concept to 9 figure revenue streams\n\nBenefits:\nCompetitive Base Salary\n\nMeaningful equity & financial upside - a real % of the company\n\nAnnual bonus target based on personal and company performance\n\nHealth, Dental, Vision available\n\nUnlimited PTO - we care about impact, not tracking days you’re out\n\n401k with company match %\n\nGenerous parental leave policy\n\nAbout The Role\nAs an MLE on the Core Signals team, you will primarily be focused on (1) the representation learning surrounding our fundamental user-behavioral modeling problems and (2) using those core models to power new and existing products.\nThis role involves a lot of collaboration with the Product org and Applications team to realize these R&D gains - but is ultimately a \"full stack\" ML role. Day to day responsibilities include data processing, model training, deployment, and evaluation.\nA good amount of \"wearing your Product hat\" is expected, as well as the ability to flex into some other functions as needed - we are a quickly growing startup after all.\nWhat it takes to succeed in this role:\nYou understand enough about machine learning to be able to apply it to novel problems and suggest improvements to our current setup, or even radical new approaches. Previous publication experience is not required.\n\nYou've worked on and can speak to at least some of: representation learning, embeddings drift, CTR modeling, sequence modeling, etc., preferably on \"big data\" in an industrial setting.\n\nSkill and attitude wise, you can quickly contribute to the non-research components of our pipeline. This includes things such as data orchestration, build systems, and experiment tracking. Although we use a combination of open source products like Airflow, Bazel, Github CI/CD, and Spark, prior experience with these specific solutions is not needed. However, a good part of your day to day will involve interacting with these systems, so you should be comfortable with getting your hands dirty.\n\nGood product sense - you have opinions on what we should and shouldn’t be doing both in chasing product-market fit and on the implementation side.\n\nA reasonable estimate of the current base salary range at the time of posting is below. Base salary does not include other forms of compensation or benefits. Actual base salary within the specified range is comprised of several components, including but not limited to applicant's skill, prior relevant experience, specific degrees and certifications, job responsibilities, market considerations and the location of the position. \nBase salary range: $180,000-$275,000\nWe prioritize attitude, culture, and general (technical) fit over matching perfectly into one of our job descriptions. If our mission and work resonates with you, we encourage you to apply. Tell us how you can help drive our products forward, even if you don’t feel like you are a perfect fit for some of the listings.","description_format":"text","description_chars":4423,"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":["401k plan","Equity","Parental leave","Unlimited PTO"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"Canada","iso":"CA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Predictive Analytics","Advertising","Marketing & Sales AI"],"lifecycle":[{"event":"open","at":"2024-07-17T15:05:35Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.178,"p_room":0.28,"age_days":821,"expected_fill_days":8,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":275000,"is_top_pay":true},"html_url":"https://alion.io/job/yobi-machine-learning-engineer-core-signals-2","json_url":"https://alion.io/job/yobi-machine-learning-engineer-core-signals-2.json","meta":{"generated_at":"2026-10-17T15:24:45Z","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":20829,"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":1018},"rest":"https://alion.io/mcp/rest/get_company?id=1018"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fyobi-machine-learning-engineer-core-signals-2"},{"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%2Fyobi-machine-learning-engineer-core-signals-2"},{"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%2Fyobi-machine-learning-engineer-core-signals-2"},{"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/yobi-machine-learning-engineer-core-signals-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fyobi-machine-learning-engineer-core-signals-2"}]}
