About the Role
Any additional information you require for this job can be found in the below text Make sure to read thoroughly, then apply. Uber's Core Security Engineering org is re-imagining how identity is protected and managed by fusing large-scale machine learning with modern agentic AI. As a Senior Machine Learning Engineer you'll lead two complementary tracks: building context-aware authentication models that decide when and how to challenge users, and creating an agentic AI workflow engine that automates IAM operations-think an LLM-powered copilot that files, executes, and verifies tasks such as user provisioning, access reviews, and policy changes. No prior security background is required; what matters is your ability to ship reliable, production-grade ML systems. What You'll Do Risk-based authentication - Design and deploy models that fuse behavioral biometrics, device posture, and network context to produce dynamic risk scores and trigger step-up factors or session revocation in real time.
Agentic AI workflow engine - Architect an LLM-driven orchestration platform that can observe IAM events, plan multi-step remediation or provisioning flows, and take safe actions across systems such as Okta, Active"Directory, Duo, and ServiceNow.
Productionize models and agents in high-scale, low-latency environments handling millions of auths and thousands of automated tickets per day.
Build continuous feedback loops so both models and agents learn from outcomes and human approvals.
Collaborate closely with IAM, SSO, infra, and detection teams to integrate your solutions end-to-end-from real-time decisioning to post-incident forensics.
Lead design reviews, mentor engineers, and evangelize ML/GenAI best practices across the security and infrastructure orgs.
Minimum Qualifications 5+"years building ML or applied data-science solutions, hands-on experience with generative-AI or agentic systems.
Expert in Python, with proficiency in Go or Java; deep familiarity with ML/LLM frameworks such as PyTorch, TensorFlow, JAX, or LangChain.
Demonstrated success running ML services in production at large scale and low latency.
Strong communication and leadership skills; proven ability to set technical vision and influence roadmaps.
Preferred Qualifications Experience with reinforcement learning, retrieval-augmented generation, or structured tool-use frameworks for AI agents.
Hands-on work with risk scoring, anomaly detection, or fraud prevention pipelines.
Familiarity with identity systems (Okta, Entra ID/AAD, SSO, MFA) or enterprise workflow tools (ServiceNow, Airflow) is a plus-but not required.
Publications, open-source contributions, or patents in ML, GenAI, or security automation.
