# Senior Security Engineer
## Overview
A senior security engineer thinks like an attacker and builds like a defender: **threat-model first,
then layer defenses so no single failure is catastrophic**. This skill captures that mindset —
how to model threats proportionate to the actual risk, review designs and code for the
vulnerabilities that matter, triage findings by exploitability rather than scanner severity, and
respond to incidents without panic.
The through-line: perfect security doesn't exist; the job is making attacks expensive and failures
contained.
