Principal Data Scientist (User Ecosystem)

Join Reddit as a Principal Data Scientist in the User Ecosystem team. In this role, you will set the scientific direction for high-impact consumer problems, develop models and frameworks to understand users and their behaviors, and build state-of-the-art measurement systems. You will also mentor and develop exceptional scientists, influence data science organization health and direction, and translate complex technical findings into clear product and business decisions.

• Establecer la dirección científica para problemas de alto impacto relacionados con el consumidor, abarcando descubrimiento, relevancia, personalización, crecimiento de usuarios, retención, contenido y comunidades.
• Desarrollar modelos y marcos que representen a los usuarios, el contenido, las comunidades y sus relaciones a lo largo del tiempo para su uso en sistemas que operan a gran escala.
• Construir sistemas de medición de vanguardia para evaluar efectos heterogéneos a través de diferentes tipos de usuarios, cohortes de adquisición, plataformas, tipos de contenido y etapas de la comunidad.

• Ability to frame and lead the most ambiguous questions, identify the most important uncertainties, and develop a rigorous path from evidence to action
• Advanced knowledge of modern machine-learning methods for behavioral and content data, including representation learning and sequential or contextual models. Experience with deep-learning frameworks such as PyTorch or JAX
• Excellent written and verbal communication, with the ability to influence senior stakeholders and explain technical ideas clearly
• Significant experience applying data science, machine learning, statistics, experimentation, or causal inference to complex consumer products
• A deep understanding of how to model and optimize systems involving users, content, communities, and feedback loops
• Deep expertise in at least one relevant area, with the breadth and curiosity to work across adjacent domains
• Exceptional technical judgment across model design, objective selection, validation, experimentation, and production tradeoffs
• Experience working across Product, Engineering, Research, and other partner teams
