You will leverage large datasets to develop, iterate, and continuously improve these models based on experimentation and user behavior data, driving measurable impact on engagement and retention.
In addition, you will contribute to selected marketing use cases, applying data science methods to improve targeting, campaign performance, and overall marketing efficiency. Across all your work, you will combine strong analytical thinking with a clear focus on delivering impactful solutions that align with product and business goals.

Strong understanding of machine learning and statistical modeling
Experience with:
Personalization or recommendation systems (big plus)
A/B testing and experimentation
Feature engineering and data wrangling
Good working knowledge of SQL

You think product-first and impact-driven
You enjoy solving complex problems and asking “why?”

You care about building solutions that actually reach users
Soft Skills
Strong communication and storytelling skills
Ability to translate business problems into data science solutions
Collaborative, proactive, and ownership-driven

Why This Role
Direct impact: Your work will shape core product experiences used by millions of users
Real ownership: From idea to live model in production
Strong setup: Dedicated ML Engineering support and modern data stack
Variety: Deep dive into personalization, with exposure to marketing optimization

As the team evolves towards a more fully cross-functional model, you will play a key role in establishing machine learning as a core capability within product and marketing.
