Job Description

Our mission is to bring community and belonging to everyone in the world. Reddit is a community of communities where people can dive into anything through experiences built around their interests, hobbies, and passions. With more than 50 million people visiting 100,000+ communities daily, it is home to the most open and authentic conversations on the internet. From pets to parenting, skincare to stocks, there’s a community for everybody on Reddit. For more information, visit redditinc.com.

We are looking for a senior data scientist to be a part of the Ads Data Science team. You will work closely with product managers, engineers, and data scientists to up-level the experimentation capabilities of the ads organization. You have a strong understanding of experimentation, are not afraid to challenge the status quo, and thrive in a cross-functional environment.

Reddit is continuing to grow our teams with the best talent. We're completely remote friendly and will continue to be after the pandemic.

Responsibilities:

• Elevate the experimentation practice for the Ads org by creating the right processes, templates and tools catered for ads use cases.
• Lead an experimentation council that can approve/guide experiment designs for various product launches.
• Explore new experiment designs/techniques such as small sample enhancements, Bayesian approaches, causal inference methodologies, dosage response studies, staggered experiments etc and apply them successfully for complex experiments on the ads side of the business.
• Liaise with the centralized experimentation team in building platform features to accelerate ads experimentation.
• Guide various ads product teams in understanding network effects and novelty effects when running experiments.
• Track and own the experiment calendar for the ads org. Run biweekly experiment review discussions.
• Create frameworks for making metric trade-off decisions, especially when they span multiple organizations (e.g. ads vs consumer metric tradeoffs).

What We Can Expect From You:

• Master’s or PhD degree in a quantitative major (e.g., mathematics, statistics, economics, finance, computer science). 
• 2 years of experience with experimentation, preferably for a consumer-facing service/app.
• 5+ years of experience in quantitative/modeling roles.
• Proficiency with statistical analysis and programming languages (Python, SQL).
• Understanding of experimentation and causal inference analyses.
• Experience with digital advertising is preferred, but not required.
