- Deep understanding of consumer application dynamics and the factors that drive engagement and product-market fit in discovery ecosystems.
- Experience working with experimentation frameworks, A/B testing, and performance optimization of ML systems.
- Comfortable operating in fast-paced, ambiguous environments with a strong bias toward experimentation and iteration.
- Exceptional problem-solving skills, curiosity, and drive to continuously learn new technologies and techniques.
