The Role The organization is seeking a Data Scientist to join the Data & Analytics team within the Growth organization. This is not a typical analyst role; the individual will serve as the lead growth data scientist, owning complex forecasting challenges that directly impact supply chain, marketing spend, and overall business growth. The ideal candidate brings deep experience with time series forecasting, experimentation design, and the ability to translate ambiguous business problems into data‑driven solutions. What You’ll Build Advanced Demand Forecasting Models: Solve the organization’s largest operational challenge—eliminating stock‑outs during peak periods (Black Friday, holidays) while avoiding overcommitment of capital on inventory. Marketing Spend Optimization Algorithms: Go beyond current models by incorporating seasonality, macro trends, and cross‑channel effects to improve customer acquisition cost (CAC) targeting. Experimentation Frameworks: Build incrementality testing frameworks across marketing channels (Meta, Google, YouTube) with rigorous statistical methodology. Marketing Attribution Models: Develop attribution models that account for complex customer journeys and multi‑touch attribution challenges. What You’ll Need to Succeed Experience: 5+ years of data science experience with demonstrable impact on business‑critical forecasting and optimization problems. Forecasting Expertise: Proven ability to build production models that handle seasonality, growth trends, and external factors. Experience with Prophet and a clear understanding of its limitations is a plus. Experimentation Background: Strong skills in designing proper A/B tests, incrementality measurement, and familiarity with marketing mix modeling. Technical Skills: Advanced proficiency in Python or R, combined with expert‑level SQL. The role involves building production pipelines and complex models, not just ad‑hoc analysis. Ownership Mentality: High level of agency and comfort with ambiguous problems. Ability to work extended hours during critical periods—this is a startup environment where the work directly influences the company’s trajectory. Business Acumen: Skill in translating between technical solutions and business stakeholders, including Growth, Finance, and Operations teams. Communication: Excellent written and verbal communication skills, with the ability to translate complex findings into actionable insights. Why Join Innovation in a Culture of Excellence Innovation is not just encouraged—it is a standard. The company’s flagship product is beloved by hundreds of thousands of customers worldwide, and the team continuously pushes the boundaries of technology in sleep fitness. Immediate Responsibility and Accelerated Career Growth From the first day, substantial responsibilities await—each with a direct impact on core business and product success. As part of a small, empowered team, individuals own their projects and see the tangible results of their efforts, enhancing both professional growth and the company’s trajectory. The path is challenging but rewarding, ideal for those who thrive in fast‑paced, high‑standard environments. Collaboration with Exceptional Talent The organization brings togeth...
