Summary
🤩
Rockstar🎓
Top SchoolGuillaume Winter is a Staff Product Security Engineer with 11 years of hands-on experience securing cloud platforms and developer-facing products, currently at Aiven after progressing from Senior Product Security Engineer. He brings a rare blend of sysadmin, DevOps, SRE and software engineering roots—sharpened by incident response work at Heroku and platform security at Salesforce—that informs pragmatic, production-minded security design. Comfortable navigating distributed systems and incident trenches, he focuses on making security an enabler for reliable, scalable services rather than a blocker. Based in Rennes, France, he pairs technical leadership with deep operational empathy, mentoring teams to bake security into CI/CD and platform tooling. An unconventional background that includes advanced studies and a transition from clinical training to engineering gives him a pragmatic, cross-disciplinary approach to problem solving.
