You must be willing to work in office at the Nordstrom Seattle office for a minimum of 4 days per week to be considered for this position.\nWhat You Will Do\nDevelop and improve recommendation, ranking, relevance, and personalization approaches.\nBuild deeper representations of customer intent, product understanding, and shopping context.\nEvaluate and apply modern approaches, leveraging existing open-source and pre-trained resources (e.g., Hugging Face) rather than building from scratch, including embeddings, sequence models, multimodal models, foundation models, and generative AI where they provide measurable value.\nDesign offline evaluation frameworks that better predict online customer outcomes.\nPartner with Product and Engineering to define the customer problem, desired outcome, and success metrics, and determine the appropriate scientific approach.\nDesign and analyze online experiments to understand the impact of new relevance and personalization approaches.\nInvestigate differential effects across customer cohorts, product categories, and shopping contexts.\nHelp connect candidate generation, ranking, customer understanding, product understanding, and feedback signals into a more coherent personalization system.\nDevelop reusable evaluation, feature, and modeling approaches that can be applied across multiple customer experiences.\nUse AI-assisted development in your daily workflow (e.g., Claude Code) and bring agentic and LLM-based approaches into personalization decisioning, to increase research and experimentation velocity.\nMentor scientists and help establish strong technical practices across the team.\nWhat Success Looks Like\nOffline evaluation becomes more predictive of real customer outcomes.\nRecommendation and relevance capabilities increasingly share common customer and product understanding.\nThe team tests a broader set of hypotheses faster without lowering scientific standards.\nPersonalization capabilities are reused across multiple surfaces rather than developed independently.\nNew ML and GenAI approaches are adopted based on demonstrated customer value rather than novelty.\nOther scientists improve their technical and experimental practices through your leadership.\nWhat We Are Looking For\nMinimum of 6+ years of hands-on experience in Data Science or Machine Learning roles.\nBachelor's degree in a quantitative field (e.g., statistics, computer science, mathematics, engineering) or equivalent practical experience; advanced degree preferred.\nDeep experience with recommendation systems, ranking, personalization, search, or information retrieval.\nStrong knowledge of machine learning, deep learning, experimentation, and statistical evaluation.\nExperience with embeddings, neural ranking, transformers, or related modern ML techniques, including adapting existing open-source and pre-trained models.\nStrong Python and SQL skills, including working with large-scale data (e.g., BigQuery).\nExperience using AI tools (e.g., Claude Code) in your daily workflow and applying LLM or agentic approaches to real problems.\nFamiliarity with cloud ML platforms such as Google Vertex AI or AWS machine learning pipelines is a plus.\nExperience moving models from research through production evaluation.\nAbility to reason about customer and business outcomes beyond offline model metrics.\nExperience working closely with Product and Engineering, including framing the right problem and defining outcome metrics with business partners.\nStrong technical communication and mentorship skills.\nThe Mindset We Value\nYou see the model as one part of a larger customer system.\nYou care about whether the entire system makes better choices for customers, not simply whether an offline metric improves.\nYou adopt new AI techniques when they create measurable value and simplify or scale how the team works.\nThis is an applied data science role, not a research or reporting function: you identify the problem, propose a solution, iterate quickly, and deliver with Engineering.\nPay Range Details\nThe pay range(s) below has been provided in compliance with state specific laws. Pay ranges may be different for other locations. \nPay offers are dependent on the location, as well as job-related knowledge, skills, and experience.\n$166,000.00 - $258,000.00 AnnualWe’ve got you covered…\nOur employees are our most important asset and that’s reflected in our benefits.
