Why this role now
The company is maturing its application security function from a position of strength — a recent penetration test returned zero findings — and is investing ahead of an expected increase in AI-assisted vulnerabilities targeting the financial sector. The AppSec Engineer joins with a clear mandate: own remediation of validated findings, build the secure development lifecycle that prevents future vulnerabilities, and establish the AppSec program credibility that banking customers and their regulators increasingly audit directly.
