Summary
🤩
Rockstar🎓
Top SchoolJon Hermansen is a seasoned software engineer with 17 years of hands-on experience specializing in QA, web automation, and cloud-enabled testing. He has led testing for customer-facing security products at Mimecast and designed resilient automation frameworks using Protractor and Cypress (TypeScript/JavaScript) to drive reliable end-to-end and component tests. Jon pairs deep testing discipline with platform-level involvement—contributing to code reviews, deployments, CI infrastructure, and flaky-test monitoring—to reduce risk and surface inter-component dependencies early. His background spans startups to large enterprises, from building REST APIs and CI systems to identifying security issues like XSS in production-facing apps. Based in Greater Boston, he now applies that blend of development and QA expertise as a software engineer at Obsidian Systems, bringing a pragmatic focus on testability and operational support that often uncovers latent platform issues before customers do.
