About the Role

Uber's newly formed AI Security team, part of the Core Security Engineering organization, is building the foundation for dynamic, data-driven security systems. We're evolving Uber's Zero Trust Architecture (ZTA) to be more risk-adaptive across authentication and authorization, moving beyond static rules and manual approvals toward real-time, ML-driven access decisions that secure both humans and AI agents without slowing them down.

As a Senior ML Engineer, you'll translate ambiguous business and security needs into concrete ML problems, design and iterate on solutions, and take them end-to-end into production. This is greenfield work at the intersection of ML, security, and infrastructure, shaping how Uber secures AI at scale.

What the Candidate Will Need / Bonus Points

---- What the Candidate Will Do ----

• Translate business and security needs into well-defined ML problems.
• Develop, iterate, and productionize ML models that drive risk-adaptive decisions in real-time.
• Engineer features from Uber's risk systems, logs, and contextual signals.
• Integrate ML systems into Uber's critical access pathways (containers, APIs, gateways, data).
• Collaborate across Security, Risk, and Infra teams to deliver scalable, production-ready solutions.
• Provide leadership by mentoring junior engineers, evangelize ML best practices, and help shape ML strategy within AI Security.

---- Basic Qualifications ----

• 5+ years experience in formulating ML problems from ambiguous business requirements, especially in risk, fraud, or security contexts.
• Proficiency across a broad range of ML algorithms: tree-based models (XGBoost, LightGBM), classical statistical models (logistic regression, SVMs), and deep learning architectures (CNNs, RNNs, Transformers), with the ability to select and apply the right approach based on context and data characteristics.
• Hands-on experience with feature engineering, model development, and productionization of ML pipelines.
• Proficiency in Py Torch, Tensor Flow, or similar ML frameworks, and in Python or comparable languages for scalable, production-grade systems.

---- Preferred Qualifications ----

• Proven ability to own ML systems end-to-end: from requirement discovery → feature design → modeling → deployment.

• Deep experience with advanced ML techniques, including ensemble methods, neural networks, graph-based models, and handling challenges like imbalanced data, feedback loops, and iterative retraining.

• Familiarity with large-scale data/infra systems (Kafka, Pinot, Hive, Cassandra, Spark, Flink).

• Background in access control, authentication, or enterprise security systems.

• Track record of technical leadership: mentoring engineers, driving cross-functional initiatives, or shaping ML/security strategy.

• For San Francisco, CA-based roles: The base salary range for this role is USD**$202,000 per year**

• USD**$224,000 per year**.

• For Seattle, WA-based roles: The base salary range for this role is USD**$202,000 per year**
