We’re looking for a Lead Machine Learning Scientist to own and scale ML-driven Marketing/Growth/Product capabilities at Dave. This role will drive how we use data and machine learning to improve acquisition, engagement, retention, and monetization across a multi-product ecosystem.

You will help identify high-impact opportunities, building production-grade models, and shaping the roadmap for ML in Marketing/Growth. This is a highly strategic and hands-on role requiring both technical depth and business acumen.

ML Strategy for Marketing/Growth

Architect and lead machine learning solutions across teams, driving multi-person, cross-functional initiatives
Define and execute the roadmap for applying ML to improve marketing efficiency and growth
Proactively identify high-impact opportunities where ML can drive step-function improvements (not just respond to requests)
Partner closely with Marketing, Product, and Finance to align ML investments with business priorities

Build High-Impact Models

Lead development and deployment of core models, including:
- Propensity (conversion, engagement)
- Churn prevention and intervention
- Customer Lifetime Value (LTV) models, co-develop with Finance to align on assumptions, definitions, and business use cases
- Cross-sell / next-best-action models across Dave’s products
Improve onboarding, targeting, personalization, and segmentation at scale
Work across modeling lifecycle from problem formulation, training, calibration, and iteration in production
Build agentic engineering workflows that accelerate development, testing, and documentation

Data & Platform Leverage

Analyze large and complex dataset; Identify and evaluate high-leverage internal and external data sources to improve model performance
Build business cases for new data acquisition and lead onboarding efforts
Ensure models are scalable, measurable, and tightly integrated into marketing workflows

Optimization & Efficiency

Continuously evaluate and improve marketing spend efficiency through ML-driven insights and models
Identify and resolve cost inefficiencies across models and pipelines
Design and optimize reward and incentive strategies (e.g., referral incentives, promotional offers) to maximize user acquisition, activation, and retention while managing cost efficiency
Develop models to determine optimal reward levels and targeting, balancing conversion lift with incremental cost to improve ROI
Evaluate and measure incrementality of rewards and promotions using experimentation (A/B testing, uplift modeling) to ensure incentives drive true behavioral change rather than subsidizing existing demand

Technical Excellence

Set standards for model development, experimentation, and validation
Promote adoption of modern ML techniques, leverage pre-trained models, including effective use of AI/LLMs where applicable

Experience Required

7+ years of experience in machine learning, data science, or a related field
Proven experience building and scaling ML models in production environments
Strong experience with marketing-related models (propensity, churn, LTV, targeting, etc.)
Demonstrated ability to lead large, ambiguous, cross-functional projects
Strong programming skills (Python, SQL) and experience with ML frameworks (e.g., scikit-learn, TensorFlow, PyTorch)
Familiarity with Marketing KPIs (CAC, ROAS etc)
Strong communication skills—you can translate between technical and business audiences

Experience Preferred

Experience in fintech or multi-product ecosystems
Familiarity with attribution, MMM, or marketing measurement
Experience with large-scale data platforms (e.g., Snowflake)
