Summary
Jeffrey Stiles is a senior security engineer with 11+ years of hands-on experience conducting penetration tests, PCI DSS and SOC 2 assessments, and building tooling to automate vulnerability discovery and reporting. Based in Tacoma, he blends a developer’s mindset with deep offensive security expertise, regularly writing code to reproduce, exploit, and communicate findings. His career spans client-facing consulting and in-house security roles where he led remediation, incident response, and forensic investigations for complex networks and applications. A perpetual learner, he holds an MSc in Information Security (Distinction) from Royal Holloway and pairs that formal training with a habit of “overdoing” curiosities—often inventing bespoke testing utilities rather than relying solely on off-the-shelf tools. Comfortable in ambiguity, he mentors driven teammates and prefers tackling gray-area problems that require both creativity and discipline. If something needs to be figured out, hardened, or explained to non-technical stakeholders, he’s the engineer who will both discover the issue and build the fix.
