About the role Hands-on offensive security, from day one.
You'll run our maturing offensive solution on real client engagements, hunt 0-days in our own systems and in the wild, and use that expertise to steer the AI that automates offensive security at scale.
You'll break real systems for clients across banking, healthcare, and large consumer brands, and help set the bar for what as good as a human pentester actually means.
As one of the first hires in the security team, you will have the unique opportunity to shape and define the entire function and build out a world-class team.
What you'll do Run our offensive solution on real client engagements - scope, execute, triage output, kill false positives, and deliver findings clients can act on.
Advise clients through deployment and remediation as a trusted security partner; travel to client sites and switch between engagements at a classic pentest cadence.
Pentest Code Wall's own systems - find the vulns before our harness can, and be our own first customer.
Hunt for vulnerabilities between engagements, on open-source and in-the-wild targets.
Steer the harness: define what it should catch, validate and triage its output, and benchmark agent vs. human until the gap closes.
Transfer knowledge and findings into the forming internal security team.
What we're looking for Senior enough to run an engagement solo - scoping to delivery - with a proven track record of high-quality pentest results.
Thrives in early-stage environments where the requirements moved daily (0-1).
Core strength in web / App Sec and source-code review; also high-value: internal / Active Directory, cloud (AWS/GCP/Azure), CI/CD and supply chain.
You use AI in your workflow and have a nuanced, opinionated view of what it can and can't do.
Comfortable being client-facing, mobile, and switching between different engagements.
Sharp problem-solving and real attention to detail in vulnerability identification.
Bonus You build your own offensive tooling - a builder mindset that scales your impact.
Published CVEs / GHSAs, or a strong bug-bounty track record.
Conference talks, CTF placements, or other public recognition in the security community.
Experience with AI/ML systems and their unique security challenges, or contributions to open-source security tools and research.
