Senior Software Engineer at Squarespace
Broomfield, Colorado, United States
Summary
👤
Senior🎓
Top SchoolZach Passen is a senior front-end engineer with 11 years of experience focused on the “front of the front end”—HTML, CSS and vanilla JavaScript—who builds accessible, standards-driven web experiences and teaches others to do the same. At Squarespace and prior companies he led accessibility programs, authored internal guidelines and training, and ran audits and remediation efforts that measurably reduced violations. He doubled test coverage at Healthvana by migrating Selenium suites to TestCafe and introduced automated axe-based accessibility testing, and he’s comfortable driving large refactors to improve code quality and accessibility. Based in Broomfield, Colorado, Zach prefers stable, mission-focused organizations and explicitly avoids startup/early-stage roles as well as AI or crypto work. An effective communicator and public speaker, he combines pragmatic engineering with advocacy—often surfacing accessibility gaps that others miss.
