In this team you'll have a unique opportunity to have first-hand exposure to the strategy of the company in key security initiatives, especially in building scalable and robust, intelligent and privacy-safe, secure and product-friendly systems and solutions.
Our challenges are not some regular day-to-day technical puzzles -- You'll be part of a team that's developing novel solutions to first-seen challenges of a non-stop evolvement of a phenomenal product eco-system.
The work needs to be fast, transferrable, while still down to the ground to making quick and solid differences.
Responsibilities:
Build machine learning solutions to respond to and mitigate business risks in eHealthcare products/platforms.
Such risks include and are not limited to abusive accounts, fake engagements, spammy redirection, scraping, fraud, etc.
Improve modeling infrastructures, labels, features and algorithms towards robustness, automation and generalization, reduce modeling and operational load on risk adversaries and new product/risk ramping-ups.
Uplevel risk machine learning excellence on privacy/compliance, interpretability, risk perception and analysis.
Qualifications:
Master or above degree in CS, EE or other relevant, machine-learning-heavy majors.
Solid engineering skills.
Proficiency in at least two of: Linux, Hadoop, Hive, Spark, Storm.
