From the employer

WHO ARE WE?

Launch Potato is the discovery and conversion company. We reach tens of millions of people every month through our brands, including FinanceBuzz, All About Cookies, and OnlyInYourState. We turn that attention into real outcomes for our partners, some of the world's leading companies.

Our mission: create predictable, high-value customer acquisition at scale by connecting discovery, intent, and performance across category-leading consumer brands in finance, travel, and entertainment.

We run profitable and bootstrapped, with a South Florida HQ and a remote-first team across 18 countries.

WHY JOIN US?

You own outcomes here, not tasks. We measure work by impact, not activity. The pace is real, and change is constant, so the people who do best turn change into opportunity instead of waiting for it to settle. Feedback runs direct and lands with respect. Ordinary people make themselves extraordinary at Launch Potato.

MUST HAVE:

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: the 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

EXPERIENCE: 5+ years in a hands-on, in-the-weeds applied data science role delivering measurable business impact.

YOUR ROLE

Own the full data science engine for a priority vertical, from business problem to deployed model to live ROAS performance, driving measurable revenue and media efficiency. This is a hands-on, in-the-weeds role: you are heavily immersed in the data and the modeling, framing the business problem directly with stakeholders, building and validating the model, handing the ML-engineering last mile to your ML engineering partner, and staying engaged through deployment, monitoring, and performance analysis.

You will start focusing on Insurance and Advertiser Quality, with scope that broadens over time. Your primary metric is ROAS.

OUTCOMES

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, low correction burden
Identify and leverage net-new modeling opportunities the business has not flagged

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
