Senior Data Scientist, AdTech (Remote, International)

Function: Engineering, R&D → Data Science / Machine Learning / Operations ResearchAbout PulsePoint:PulsePoint is a fast-growing healthcare technology company (with adtech roots) using real-time data to transform healthcare. We help brands and agencies interpret the hard-to-read signals across the health journey and unify these digital determinants of health with real-world data to produce the most dimensional view of the customer. Our award-winning advertising platforms use machine learning and programmatic automation to seamlessly activate this data, making marketing, predictive analytics, and decision support easy and instantaneous.Sr. Data Scientist, AdtechThis is a visionary leadership role on our Data Science Engineering team, the Sr. Data Scientist will focus on optimizing real-time bidding strategies and auction mechanics to efficiently spend ad budgets and deliver against campaign targets. In addition to the above, you will work with the greater Data Science/Engineering teams on:

• Improving existing solutions for page contextualization or developing new techniques;
• Developing new or improving existing models of event predictions;
• New feature engineering for multiple machine learning models:
• Supply embeddings and/or segmentation, and supply quality metrics;
• Fraud detection, etc.
• Mining different data sources;
• Supporting existing codebase for data integration and production support for our core models.

Location: U.S. or EU (for EU candidates, we would expect to end days at 12-1pm EST)-We can hire as FTE in Canada, U.S., and the UK. Other countries we can hire as long-term contractorRequirements:

• 5 years minimum of experience in data science

Key Skills: Python, Algorithms, Optimisation, NLP, Data Mining, Statistical Analysis, Neural Networks, Generalised Linear Regression, Multiclass Classification, Java, R

• Advanced knowledge of Python using standard DS packages (numpy/pandas/scikit, etc.); Being able to optimize and speed-up code.
• 3+ years of RTB Auction or similar online technologies.

In addition to the above, you’ll need to have strong knowledge in the following areas:

• Algorithms and Data Structures (e.g., sorting, search tree, binary heap, trie; time & mem complexities of algorithms)
• Probability and Statistics (e.g., hypothesis testing; Markov process and its stationary distributions, stochastic matrix and its properties; Bayesian inference)
• ML & DS (e.g., dimensionality reduction, geometry of PCA / SVD and of L1 / L2 regularisation, Decision trees and their ensembles, collaborative filtering, Thompson sampling / MCMC, Neural Networks, etc.)
