* Develop compelling measurement plans and model/forecast scoring methods to track predictions against actuals (while considering the cumulative and delayed effects of marketing efforts and uncertainty)
* Design, develop and program methods, processes, and systems to consolidate and analyze unstructured, diverse "big data" sources to generate actionable insights and solutions to generate business impact
* Work across multi-disciplinary teams to translate business needs into testable hypotheses and design experiments to test said hypotheses
* Collaborate with other members of the team to support investigation across a variety of topics
* Research, recommend, and apply appropriate statistical, econometric, mathematical, and computational modeling concepts across domains
* Work with Machine Learning Engineers to convert experimental code to production code
* Unit test production model code to ensure quality
* Take an active role in recruiting, training, guiding, and mentoring junior team members
* Ensure data and code integrity by conducting documentation and code reviews
* Implement strategic analyses with the know-how to balance getting the details right, while still moving at the speed of business

You have:

You will stand out if you have one or more of the following:
* The ability to quantify indirect effect of treatments utilizing Bayesian/Causal Networks or Halo Effects
* Experience with Bayesian Belief Networks
* Experience incorporating expert qualitative business knowledge and A/B test results to adjust and tune model results
* Familiarity and experience with conformal prediction, and diffusion methods is a plus
* Demonstrated experience with applying integer and linear optimization methods to drive business goals/KPI outcomes
* Strong working knowledge of causal inference techniques
* Familiarity of advanced optimization methods
* Demonstrated success in Data Science within the Marketing Domain
* Experience working in CPG, Media, or Retail on the client or agency side
* Domain knowledge on marketing and/or Market Mix Models
* Up to date and passion for staying current with various modeling techniques and a demonstrated history of utilizing champion challenger principles to ensure model
