Our Offer-to-Product matching system uses search, machine learning, and simple, practical engineering to make large product data useful. We care about results that our content and product teams can feel — how many offers we match, how correct the matches are, how much we cover.\u003C/p>\u003Ch3>\u003Cstrong>What we mean by \"ML Engineer\"\u003C/strong>\u003C/h3>\u003Cp>For us, an ML engineer works across several areas, not just one: software engineering, training models, verifying models (including how sure we are about the results), and data analysis. You do not need to be the best at every one, but you should be comfortable with all of them and able to move between them as the task needs.\u003C/p>\u003Ch3>\u003Cstrong>What you will do\u003C/strong>\u003C/h3>\u003Cul>\u003Cli>Own problems from start to end — understand the business need, choose an approach, ship it, and measure it in production.\u003C/li>\u003Cli>Decide if a problem even needs machine learning. Often a good rule or a simple baseline is the right answer, and we want you to start with the simplest thing that gives value.\u003C/li>\u003Cli>Build and improve matching, ranking, and data-quality solutions — using classic ML, search, and more and more LLM-based methods where they help.\u003C/li>\u003Cli>Work closely with content and product teams: turn unclear business problems into clear, planned steps, and explain the trade-offs.\u003C/li>\u003Cli>Move decisions forward — suggest a direction, write it down, and help the team reach a conclusion.\u003C/li>\u003Cli>Look at the whole system: understand how the parts (search, features, model, thresholds, deployment) and the nearby services work together.\u003C/li>\u003C/ul>\u003Ch3>\u003Cstrong>What we are looking for\u003C/strong>\u003C/h3>\u003Cul>\u003Cli>Practical, business-first thinking: you see technology as a way to reach a goal, and you weigh effort against value.\u003C/li>\u003Cli>Real experience with applied machine learning: training and checking classic ML models (for example XGBoost, scikit-learn), thinking about uncertainty, doing error analysis, and knowing when ML is needed.\u003C/li>\u003Cli>MLOps: comfortable putting models in production and operating them (deploy, monitor, maintain).\u003C/li>\u003Cli>Good software engineering: you write reliable production Python and can own your code from start to end.
