Sr. Data Scientist

Job Description

We are seeking a Senior Data Scientist to lead Marketing Mix Modeling (MMM) and conversion/attribution analytics end-to-end. You will build the models, ship the pipelines working with Data Engineers, and work directly with Sales, Strategy & Insights, and Planning teams to turn measurement into revenue. This is not a research engagement - we need someone who has shipped MMM and statistical models to production systems, influenced real ad spend decisions, and who can hold their own in a room with both Data Scientists and Ad Sales leaders.

What You Will Do

MMM & Media Planning (~60%)

• Own the MMM practice end-to-end: data pre-processing, transformation, ingestion, model development, validation, calibration, and productionalize

• Collaborate with Data Engineers to build and maintain MMM pipelines on GCP that ingest spend, exposure, and outcome data across linear, ViX, audio, and digital

• Translate model outputs into planning and optimization recommendations - budget allocation, channel mix, flighting, saturation curves - that Sales and Planning teams can actually use

• Partner with Ad Sales tech team to integrate MMM functionality into a web app used by internal teams for audience insights, planning recommendations and campaign measurement

• Calibrate MMM against incrementality tests and lift studies; reconcile MMM with MTA and platform-reported metrics

Conversion & Attribution Analytics (~30%)

• Build and productionize multi-touch attribution (MTA) models that integrate with our identity graph and clean room infrastructure

• Work with 1P, 2P and 3P conversion data (pixels, ACR, digital/streaming viewership, retail/sales, online search activity, etc.) to measure campaign outcomes

Execution & Stakeholder Ownership (~10%)

• Ship production code. You will own the models and collaborate with the Ad Sales tech team to develop pipelines and model-serving endpoints

• Independently present and defend measurement work to leadership (VP and above) and to external stakeholders including agencies and advertisers - translating model mechanics into business narratives without losing technical rigor

• Work independently - this engagement requires someone with high agency and ability to take a business initiative and turn it into a productionalize measurement product

• Work in a tech team - this engagement requires working with peers in the tech team, including Data Engineers, Data Scientists, Full-stack Developers, and Architects, to integrate models in end-user facing web applications.

Skills and Requirements

• 7+ years of applied data science experience, with at least 4 years focused on MMM and marketing/media measurement

• Production ownership: you have built and shipped data pipelines and model-serving integrations - not just notebooks handed off to engineering (be ready to talk through specific systems you have put into production and the business outcomes they drove)

• Strong Python/R and SQL skills; experience using modern data stack (cloud data warehouses, orchestration frameworks, version control, CI/CD)

• Demonstrated experience with incrementality testing, lift studies, and MTA, including the messy parts: test design, power analysis, reconciling conflicting signals across methodologies

• Experience with at least one major MMM framework, such as Meridian, PyMC, Robyn, or LightweightMMM, and can speak to the tradeoffs in going with a bespoke model versus using such frameworks

• Proven ability to own stakeholder communication end-to-end: presenting to senior internal leadership (VP+), agencies, and clients without needing a layer of translation (you move swiftly between a Bayesian prior conversation and a channel-mix recommendation conversation without skipping a beat)

• Able to work hybrid from our NYC office (4 days/week) Strongly Preferred:

• Prior experience at a publisher, broadcaster, streaming platform, ad-tech company, or agency/measurement firm working on media-side measurement

• Familiarity with ACR data, set-top box data, or digital/streaming viewership data

• Experience working with 3P conversion/outcome data providers (NIQ, Polk, EDO, or similar)

• Exposure to both pre-sales (research, planning, recommendation) and post-sales (outcomes, renewal) measurement workflows

• GCP experience (BigQuery, Vertex AI, Composer)

Nice-to-haves:

• Causal inference depth: geo-based measurement (GeoLift, CausalImpact), synthetic controls, uplift modeling

• Experience with clean room environments (Snowflake, AWS, Habu, InfoSum)

• Familiarity with identity resolution and cross-platform measurement
