• Partner with product, operations, and AI stakeholders to answer high-impact questions.
• Support experimentation and analysis that improves task design, data quality, and model outcomes.
• Create dashboards and reporting that drive fast, informed decision-making.
• Identify data gaps or quality issues and work cross-functionally to resolve them.
• Take ambiguous problems and drive them to clear, actionable conclusions.

Desired Capabilities

• 3–5 years of professional experience as a Data Scientist, with a strong track record of applying data to drive product or business decisions.
• Expert-level SQL skills
• Python experience for data analysis (e.g., pandas, notebooks).
• Strong analytical instincts and comfort working with imperfect, real-world data.
• High ownership mindset and willingness to grind through complex problems.
• Ability to operate independently and deliver under tight timelines.
