## Job Description

## What You'll Build

- Advanced demand forecasting models to solve our biggest operational challenge: eliminating stock-outs during peak periods (Black Friday, holidays) while avoiding overcommitting capital on inventory
- Marketing spend optimization algorithms that go beyond our current Prophet model, incorporating seasonality, macro trends, and cross-channel effects to improve our CAC targeting

- Marketing attribution models that handle our complex customer journey and multi-touch attribution challenges

## What You'll Need to Succeed

- Forecasting expertise - you've built production models that handle seasonality, growth trends, and external factors. Bonus points if you've worked with Prophet and know its limitations
- Strong experimentation background - you can design proper A/B tests, understand incrementality measurement, and have experience with marketing mix modeling
- Advanced Python/R skills plus expert SQL - you'll be building production pipelines and complex models, not just ad-hoc analysis
- High ownership mentality - comfortable with ambiguous problems and 60+ hour weeks during critical periods. This is a startup where your work directly impacts our trajectory
- Business acumen - you can translate between technical solutions and business stakeholders (Growth, Finance, Operations teams)
- Strong written and verbal communication - you can translate complex findings into actionable insights. Your written and verbal communication skills are excellent
