AppOmni

About The Position

AppOmni is looking for a Principal Data Scientist, Risk Intelligence & AI to define and build machine-learning–driven risk scoring, prioritization, and AI-powered security workflows within our SaaS security platform. In this role, you will apply statistical modeling, machine learning, and modern AI techniques to help transform security signals into actionable prioritization, and to develop intelligent, agent-driven product capabilities that assist customers with investigation, triage, and response. You will play a key role in shaping how AI is applied responsibly and effectively in customer-facing security workflows. This is a hands-on individual contributor role with technical leadership responsibilities. You will work closely with Product and Engineering to design, build, and operationalize ML and AI systems that are explainable, reliable, and safe to deploy in production.

Requirements

7–10+ years of experience as a Data Scientist, Applied Scientist, or Machine Learning Engineer, with ownership of production systems.
Experience in security, identity, fraud, or risk modeling domains.
Strong background in statistical modeling, machine learning, and applied decision systems.
Experience designing and shipping ML- or AI-driven product features used by customers.
Experience applying ML or AI to decision-making systems that influence user workflows or automated outcomes.
Comfortability working within the GCP stack, particularly big data services, such as Dataproc (pyspark), Dataflow (Apache Beam), PubSub (Apache Kafka), data lakes (storage, partitioning, searching).
