• Built and maintained scalable data pipelines (e.g., Spark, Databricks).
• Successfully deployed machine learning models into production (e.g., via API or streaming).
• Strong SQL skills and experience with modern data warehouses — you write and optimize complex queries.
• Exceptional ability to translate mathematical and ML concepts into actionable business outcomes.
• A collaborative mindset with a drive to solve hard problems with a team‑first attitude.

• Experience with advanced experimentation (e.g., causal inference, media mix models).
• Familiarity with deep learning, time‑series forecasting, or ML monitoring tools (e.g., MLflow).
• Background in AdTech or marketing analytics.

• Ambitious people, real ownership. You’ll work with driven, entrepreneurial people who care deeply about what they deliver, challenge each other openly, and own outcomes together.
• We’re playing at the top, but we’re not done. Our apps rank in the top 5 of their categories. We’re determined to push further, compete harder, and earn the number one spot.
