Senior🎓
Top SchoolRyan Mcilmoyl is a Site Reliability Engineer with 14 years of experience building resilient infrastructure and incident response practices for high-growth SaaS businesses. He has led global SRE teams and platform initiatives at Shopify, Wealthsimple, and GlossGenius, where he designed on-call tooling, high-severity playbooks, and observability programs that measurably improved uptime and response times. Comfortable at both hands-on engineering and people leadership, Ryan has repeatedly shortened hiring cycles, scaled teams across time zones, and prepared platforms for peak events like Black Friday. Now at WorkOS, he continues to focus on operational excellence and cross-team readiness while mentoring engineers on reliability-first practices.
