Growth Marketing Manager

Earnest empowers ambitious professionals to make confident financial decisions and build the life they envision. The Growth Marketing Manager will be responsible for driving growth through effective lifecycle marketing strategies, data-driven targeting, and cross-functional collaboration to optimize customer engagement and increase loan volume.

Responsibilities:

• Own Lifecycle Strategy & Execution: Set the roadmap and execute hands-on campaigns across a meaningful portion of the customer journey to directly drive loan volume, LTV, retention, and cross-sell
• Drive Data-Backed Targeting & Creative: Establish a sharp POV on audience segmentation using behavioral and real-time data, partnering closely with Creative to push boundaries and turn opinions into evidence
• Lead the Testing Agenda: Independently design, size, and analyze rigorous A/B and multivariate tests to maximize impact and continuously optimize campaign performance
• Scale Cross-Product Growth: Build and scale the strategic programs that seamlessly move customers across the product portfolio (e.g., student loan refinancing to personal loans) to increase lifetime value
• Partner & Influence Cross-Functionally: Lead across the organization by partnering seamlessly with Data Science, Product, Creative, and Legal to build robust measurement models (incrementality, attribution) and ship flawlessly at speed

Requirements:

• 6+ years of marketing experience with a highly analytical mindset; specific channel background matters less than your ability to connect programs to business outcomes, forecast, and master the tech stack quickly
• A degree in economics, engineering, statistics, math (or equivalent experience) that proves you naturally think in numbers, build your own reporting, and understand the nuances of attribution
• A proven track record of living in a 'test-and-learn' environment—expertly handling hypotheses, sample sizes, honest data reads, and swift optimization
• Ability to form a sharp, evidence-backed perspective on audience, creative, messaging, and timing, with the communication skills to influence senior stakeholders
• A deeply proactive operator who takes extreme ownership of the work, manages shifting priorities, builds campaigns hands-on, and sweats the details others overlook
• Industry Experience: Proven track record in fintech, lending, or another regulated B2C category, including a solid understanding of compliance (CAN-SPAM, TCPA, CCPA/CPRA)
• Technical Skills: Strong SQL skills to pull your own data cuts, paired with hands-on experience utilizing lifecycle marketing tools (Braze experience is a major plus)
• Advanced Measurement: Direct exposure to sophisticated measurement methodologies, including incrementality, geo-holdouts, Media Mix Modeling (MMM), and Multi-Touch Attribution (MTA)
• Channel & Growth Scaling: Experience launching and scaling new channels (SMS, push, in-product) or successfully building cross-sell frameworks from scratch
