Senior Source Code Auditor

Most weeks involve leading audit work, mentoring junior auditors, and engaging with engineering and security leadership. You'll often own scope on the most complex code audits, lead investigations on confirmed vulnerabilities or supply-chain concerns, coordinate with development teams on remediation priorities, contribute to AppSec program design, and engage with executive leadership or external clients on findings. The work tends to be increasingly cross-functional.

What's harder than people expect is the engineering-and-audit fluency required at senior level — at this level, you need to be technically credible to engineers, audit-disciplined for compliance contexts, and strategic with security leadership. Variance is significant between internal audit at large enterprises (broader scope, less technical), dedicated AppSec teams (deeper, more remediation-focused), and third-party code audit firms (M&A diligence, regulatory compliance, OSS license audits). OSCP, GWAPT, CSSLP, or specialty credentials shape advancement.

People who tend to thrive here are technically deep about code, patient with audit discipline, and comfortable navigating between engineers, security leaders, and executives. If you want pure development work, the audit posture continues to limit. If you find satisfaction in owning the senior audit perspective on software security, the work tends to be steady, in growing demand, and a strong path into senior AppSec leadership, security engineering, or specialized M&A security consulting.
