At Abnormal Security, we safeguard the world's largest enterprises from cybercrime.

• Ship guardrails and policy engines that enable safe automation while preventing misuse, escalation, and anomalous behavior.


• Create high‑availability pipelines that ingest and correlate identity, authorization, and behavioral signals from cloud, SaaS, IAM/SSO, and audit logs.


• Drive 0→1 iteration: prototype quickly, test assumptions, learn from usage, and scale simple solutions.


• Collaborate across security, platform, and data teams; write and review technical designs; and participate in core SDLC rituals.
