Summary
👤
Senior🎓
Top SchoolCharles Clark is a Senior Application Security Engineer with 14 years of experience building and leading defenses for large consumer platforms, most notably managing Application Security, Risk Engineering, and Privacy Engineering at Etsy. He blends hands-on engineering—productionizing ML fraud models and integrating GenAI/LLMs for spam detection—with operational program ownership across ATO, WAF, IAM, and incident response. Comfortable in both data and security realms, he has a background in data engineering, ETL and clickstream systems, and has partnered closely with data scientists to bring models into production. Based in Bethlehem, PA, he now applies that cross-functional expertise at Wawa, bringing pragmatic risk-first thinking to Trust & Safety and application hardening. An unexpected throughline in his career is consistent ownership of revenue-impacting systems, from university reunion platforms to large-scale fraud prevention.
