Senior Applied Data Scientist, Abnormal AI

• 5+ years experience designing, building product machine learning applications in one of the domains of text understanding, entity recognition, NLP experience, computer vision, recommendation systems, or search
• Experience with data analytics and wielding SQL+ pandas framework to both build metric and evaluation pipelines, and answer critical questions about counterfactual treatments
• Ability to understand business requirements thoroughly and bias toward designing a simplest yet generalizable ML model / system that can accomplish the goal
• Ability to rapidly iterate on 0-to-1 model prototypes, interpret results, and pivot an approach, in order to evaluate most promising solutions as new problems arise
• Uses a systematic approach to debug data issues within both ML and heuristics models
• Fluent with Python and machine learning toolkits like numpy, sklearn, pytorch and tensorflow
• Effective programming skills which enable them to quickly add incremental logic to our codebase with readable, well tested and efficient code
• BS degree in Computer Science, Applied Sciences, Information Systems or other related engineering field

Desirable

• Abnormal Security is looking for an Applied Data Scientist to join the Message Detection - Attack Detection team
• This role would also have an opportunity to have a significant impact on the overall charter, direction and roadmap of the team.
• The Applied Data Scientist would be expected to deeply understand the domain of false negatives i.e. the current and future attacks which can cause significant customer workflow disruption and form a strong understanding of our features to
• They would help define the technical roadmap required to address the most pressing customer problems and simultaneously operate our detection decisioning system at an extremely high recall
• Deep inspection and row level data analysis of our false negatives and false positives, and produce data and feature insights to iteratively improve our detection efficacy
• Understand features that distinguish safe emails from email attacks, and utilize them effectively into our models stack and engine
• Train models and develop detectors on well-defined datasets to improve model efficacy on specialized attacks
• Identify and recommend new features groups or ML model approaches that can significantly improve detection efficacy for a product. Work with infrastructure & systems engineers to productionize signals to feed into the detection system
• Writes code with testability, readability, edge cases, and errors in mind
• Actively monitor and improve FN rates and efficacy rates for our message detection product attack categories, through feature engineering, rules and ML modeling
• Contribute in other areas of the stack: building and debugging data pipelines, or presenting results back to customers in our tools when the occasion arises
