• Expertise in Statistics: You have a strong grasp of advanced statistical modeling and causal inference methods, with a proven track record of building MMM, MTA, or similar econometric models in a D2C or E-commerce environment.
• Autonomous Execution: You have experience managing large projects independently, demonstrating the ability to deliver high-standard results without needing a predefined map.
• Complex Problem Solving: You are not afraid of being stretched and possess the technical prowess to navigate messy, large-scale datasets to extract reliable insights.
• Communicator & Influencer: You have excellent communication and presentation skills, with a demonstrated ability to influence team decisions and guide stakeholders through technical concepts.
• Strategic Thinker: You possess the business acumen to identify the "right" problem to solve at the right time, ensuring your work maximizes measurable business impact.
• Technical Proficiency: You are highly proficient in Python or R and SQL, with experience leveraging cloud-based platforms (e.g., Google Cloud/Vertex AI) to scale statistical applications.
• Mentorship Mindset: You enjoy sharing knowledge and providing clear guidance to peers and stakeholders, helping to elevate the collective technical bar of the team.
