Staff Applied Scientist, AdTech

About the Role

This is a hands-on, in-the-weeks applied data science role where you will own the full data science engine for a priority vertical—from business problem to deployed model to live ROAS performance. You will start focusing on Insurance and Advertiser Quality, with scope broadening over time. Your primary metric is ROAS.

Responsibilities

• Own the Insurance vertical's primary modeling work end-to-end with measurable ROAS impact
• Deliver buying models that maintain positive ROAS and quality
• Drive lead quality improvements across our portfolio of brands (Messaging, Funnels, Content/Listicles, and more) resulting in measurable impact to revenue growth
• Establish trusted, direct partnership with vertical business stakeholders
• Produce trusted output: validated, documented, with low correction burden
• Identify and leverage net-new modeling opportunities the business has not flagged

Required Experience

• 5+ years in a hands-on, in-the-weeds applied data science role delivering measurable business impact
• Proven experience in digital marketing, performance marketing, or the leadgen industry
• Building adtech algorithms and supporting user acquisition or paid media modeling (highly desired)
• Strong modeling fundamentals: ability to build effective models that drive business impact
• Multi-year, hands-on experience building and deploying ML solutions in the AWS cloud
• Hands-on experience across core technique areas: multi-armed bandit / reinforcement learning, recommendation and ranking systems (content-based, collaborative filtering, hybrid), funnel and monetization optimization, LTV modeling
• Expert Python and SQL

Competencies

• Business-first framing: starts with the problem and the metric, not the model
• Full-stack ownership: stays engaged from problem definition through deployed performance
• Proactive communication: closes loops without being chased
• Collaborative: leans on ML engineering for the last mile rather than working solo
• Coachable: seeks feedback and turns it into visible behavior change
• Curiosity paired with delivery discipline

Nice to Haves

• Sophisticated ML at companies where paid digital media is core to the business model
• Creative embeddings work: incorporating embeddings of creatives, videos, headlines, and search into paid media models
• Insurance domain experience
• Creating state-of-the-art Ad Ranking algorithms
• Modeling against ad-platform data points (Google, Meta, native)
• LLMs / deep learning applied to personalization or content
• Familiarity with Looker
