Bring your wide knowledge of data-science approaches to each problem you solve: the first day you might build a dashboard to track Board level metrics for the Engineering team, the second you might apply multivariate regression to identify important product features, the third you might apply active-learning techniques to guide data collection and labeling
Iteratively tackle problems as a series of experiments, proving the value of your work with proof-of-concept to ever more refined results
Convince your peers of your conclusions with clear data visualizations and well-reasoned explanation
Help grow your team through the recruitment and hiring of top data talent

Requirements

What you’ll need

4+ years of experience in data and strategy fields
Knowledge of data-science approaches; this may include machine-learning algorithms, optimization methods or symbolic artificial-intelligence, but should also include statistical methods and 'good-enough' heuristics — and the taste to know when to use each
Experience clearly visualizing information and experimental results across the full company stack: Board-level, leadership team, and individual team leads
Sufficient familiarity with production data-processing pipelines to construct them working together with generalist infrastructure engineers; tools we use include S3, FiveTran, DBT, Snowflake, Metabase, Retool, Sagemaker/JupyterNotebook (Python)
Aptitude delivering technical projects via rapid iterative development
Experience working on a small team in a fast-paced environment and are willing to experiment with different approaches before settling on the best and most elegant solution given time constraints
Excellent, proactive communication, both verbal and written.
