Summary
👤
Senior🎓
Top SchoolSamantha Chalker is an Application Penetration Testing Consultant with 11 years of hands-on AppSec experience, currently focused at IBM after senior roles at NerdWallet, Twitter, Wealthfront, and NCC Group. She blends deep technical pentesting across web and mobile platforms with program-level work — from running bug bounty programs and bot-mitigation rollouts to building vulnerability management tools and static analysis integrations. Samantha’s background as both a consultant and in-house engineer gives her a pragmatic view of risk, privacy, and secure product delivery at scale. She’s also a published researcher (creator of WSSiP showcased at Black Hat Arsenal) who pairs offensive security skills with practical development experience from earlier software roles. Based in Mukilteo, WA, she brings a developer-minded approach to AppSec that surfaces subtle frontend and protocol weaknesses often missed in standard audits.
