• Build and enhance production systems in Python by writing well-structured, flexible, and tested code

• Apply theory (bidding strategy for first-price auctions, exploration/exploitation tradeoff, budget pacing approaches) to large streaming data
• Explore and develop expertise with cutting-edge methods for streaming data and realtime control
• Propose and engineer new model features from our continuously growing and diversifying stores of data
• Collaborate closely with Business, Product, Data, and Engineering teams to co-own the rollout of new product offerings
• Develop and refine best practices for data processing, experimentation, monitoring, debugging, and analyzing data pipelines

Who you are:

• BS degree in Engineering, Statistics, Math, Economics, Machine Learning or Computer Science
• 3 to 5 years of practical experience in a Data Science or Machine Learning role, and sound understanding of Data Science and Machine Learning principles
• Experience with continuously-deployed and frequently-retrained production ML models or ETL pipelines for large and/or fast data
• Track record of problem-scoping and problem-solving on visible business initiatives
• Experience writing, reviewing, and deploying production code as part of a team
• Natural inclination to write well-structured and flexible code
• Comfort with audience-appropriate communication (to business stakeholders, engineers, data scientists)
• Strong data visualization and manipulation skills: you are able to distill a clear picture from disparate data sources reflecting a complex business
• Python expertise for scripting and model prototyping; proficient with SQL

The following experience would be a plus:

•  Ad tech or mobile game industry

Perks:

• Comprehensive medical, dental and vision insurance 
• Restricted Stock Units (RSUs) - you will have the potential of RSUs depending on the level/role
