Data Scientist

San Francisco, CaliforniaEngineering – Data Science & Analytics /US Full-time Salaried /On-siteSamba is a media intelligence company. We know what the world is watching, reading, and thinking about — in real time, at scale, across every screen. Our data exists with the consent of over a billion people, organized into the most complete picture of consumer attention ever built. The biggest brands in the world use that picture to make smarter decisions. We think it’s the most interesting data asset on the planet, because it’s the most culturally relevant. ABOUT THE ROLEWe are looking for a hands-on Data Scientist to own and deliver complex measurement science and modeling work at the core of our measurement and audience sciences products. The role requires a deep, first-principles understanding of data science and machine learning — not just the ability to apply libraries, but the ability to reason clearly about model behavior, articulate trade-offs between approaches, and make defensible methodological decisions under ambiguity. This is emphatically a coding role — you will spend the majority of your time writing production-quality Python, building and evaluating models on large-scale viewership and web data, and delivering end-to-end ML solutions.You will work closely with Data Engineering, Product, and go-to-market teams.WHAT YOU'LL DOWrite and own production-quality Python code end-to-end — well-structured, tested, documented, and built to last; PySpark proficiency is essential for working with Samba's billion-row viewership datasetsDesign, build, and deploy measurement models and statistical frameworks that power Samba’s campaign measurement, reach/frequency estimation, and cross-platform attribution productsApply the right statistical and ML technique to the right problem — drawing from hierarchical models, Bayesian inference, gradient boosting, regularized regression, causal ML, and probabilistic record linkage — and clearly articulate the reasoning behind your choicesBuild and evaluate multi-touch and multi-channel attribution models; apply Causal ML methods — counterfactual modeling, meta-learners (S-learner, T-learner, X-learner), and heterogeneous treatment effect estimation — to advertising and viewership measurement problemsPartner with Data Engineering to define data requirements, validate pipelines, and ensure model inputs are reliable, scalable, and production-readyLead technical design reviews and contribute meaningfully to architecture decisions across the Data Science teamMentor junior Data Scientists through code review, pairing, and structured technical feedback — raising the team's technical floorCommunicate measurement methodologies and findings clearly to technical and non-technical audiences, including senior leadership and external clientsWHO ARE YOU5-7 years of professional data science experience — hands-on, delivery-focused, and measurable in shipped models and production systemsExpert-level Python — clean, modular, testable, production-ready code is your standard, not your aspirationAdvanced PySpark and Databricks — comfortable building and optimizing data pipelines and ML workflows on billion-row datasetsDeep, first-principles command of statistics and ML — you can explain from the ground up how these models work and you apply this understanding to make better modeling decisionsSolid grasp of experimental design — A/B testing, randomization, power analysis, and the conditions under which observational causal inference is appropriateFluent in the full ML lifecycle: feature engineering, model evaluation, deployment pipelines, drift monitoring, and iterative improvement in productionHands-on experience with uplift modeling, synthetic control, difference-in-differences, or propensity-based approaches applied to advertising or media outcomesStrong ownership mindset — you drive projects independently and are comfortable owning your models from data exploration through production delivery, with minimal hand-holding.Clear communicator — able to translate statistical reasoning and model behavior into language that drives decisions with product, engineering, and leadershipExperience with multi-touch attribution (MTA) or multi-channel attribution modeling — understanding of the limitations of rule-based approaches and the methodological trade-offs of data-driven alternativesHands-on experience with Causal ML methods — counterfactual modeling, meta-learners, and heterogeneous treatment effect estimation — applied to advertising or media measurement outcomesDirect exposure to TV or digital viewership data — ACR signals, STB data, viewership panels, or cross-platform measurement (linear + CTV/OTT)Familiarity with the measurementt vendor landscape (Nielsen, Comscore, VideoAmp, iSpot) and industry standards (MRC, GRP/TRP frameworks)Advanced degree (MS or PhD) in Statistics, Mathematics, Computer Science, or a related quantitative field — or equivalent depth demonstrated through work$150,000 - $185,000 a yearSamba expects to offer a base salary between $150,000 - $180,000 USD per year for roles to be performed in San Francisco or California; actual base salary offered will depend on various factors including but not limited to location, experience, and performance.
