Scrunch, a venture-backed startup, is on a mission to bring brands to an AI-first future—where people increasingly rely on LLMs to discover, understand, and act on information that matters to them.
As AI search and conversational agents replace traditional web search and browsing, Scrunch helps marketing teams rethink how their products and services are discovered and surfaced on AI platforms like ChatGPT, Claude, Gemini, and more—working with AI platforms, not against them. This shift represents the biggest change to marketing since the dawn of the internet.
With $26M in backing from Mayfield Fund, Decibel, Homebrew, GTM Capital, and leading Silicon Valley founders and operators, Scrunch has scaled rapidly since commercial launch. Today, more than 500 paying brands—including Fortune 500 companies like Lenovo, category-defining brands like Skims, and breakout startups like Clerk—use the platform.
About the RoleWe’re looking for a Data Scientist to help us build, measure, improve AI-augmented information retrieval and web visibility, spanning retrieval & ranking, NLP, experimentation, and knowledge graph / semantic web systems.
You’ll partner closely with Engineering, Product, and Marketing to turn ambiguous questions into measurable work and shippable features.
Location: NYC | Hybrid | 3x/week
What You’ll DoDesign, prototype, and productionize models/algorithms for retrieval, ranking, and relevance quality across web and AI-assisted surfaces.
Build NLP pipelines (classification, entity extraction, topic modeling, sentiment analysis) and validate them with clear offline + online metrics.
Own measurement and experimentation: hypotheses, experiment design, guardrails, and readouts that drive decisions.
Develop simulation / modeling frameworks to forecast outcomes, test policies, and stress-test system behavior under different assumptions.
Contribute to knowledge graph / semantic web work: schema design, entity resolution, and downstream ML / GenAI applications.
Translate technical work into crisp narratives for stakeholders (product tradeoffs, confidence, limitations, and next steps).
Contribute to external thought leadership where it makes sense (blog posts, talks, papers).
Strong foundations in statistics, experimental design, and model evaluation.
Hands-on experience with information retrieval / ranking / search relevance, ideally in AI-augmented contexts.
Experience building and evaluating NLP models in production or research settings
Proficiency in Python and SQL
Strong communication: you can explain what you did, why it matters, and how confident you are, without hand-waving.
Deep comfort with the web as a system (crawl/index realities, domains, content structure, measurement constraints).
Experience working with non-representative data and making results more trustworthy through sampling-aware analysis (bias checks, adjustments, uncertainty).
Work with noisy/partial labels, long-tailed queries, drifting content, and evaluation that mixes offline + online signals
Reinforcement learning / control theory / optimal control applied to ranking, allocation, or policy optimization.
Semantic Web / Knowledge Graph tooling (RDF/OWL concepts, graph DBs, SPARQL, entity resolution).
SEO + AEO familiarity and the ability to connect technical visibility drivers to business outcomes.
Marketing analytics experience (attribution-adjacent thinking, funnel measurement, incrementality).
Publications in top-tier venues (e.g., SIGIR and related IR/NLP conferences) or equivalent demonstrated research depth.
Languages: Python, SQL
Data: BigQuery, Clickhouse, Postgres, dbt, Airflow
ML/NLP: PyTorch, Hugging Face, Vector Databases
