Summary
👤
Senior🎓
Top SchoolMark Corsillo is a Staff IAM Engineer with a decade of hands-on experience building and automating identity and access solutions, primarily with SailPoint IdentityNow across Workday and Active Directory ecosystems. He’s known for pragmatic automation using PowerShell and APIs—authoring reusable modules and orchestration patterns that powered migrations, tenant documentation, and large-scale provisioning workflows. His background spans enterprise and services roles at Wayfair, Chewy, Bose, and ProofID, where he designed integrations, led implementations, and reduced license and operational costs through data-driven remediation. A SailPoint Developer Community Ambassador, he combines deep product expertise with developer-first tooling and an emphasis on internal, in-house IAM roles rather than consulting. Notably, he’s built tooling that converts IdentityNow tenant configurations into as-built documentation and led access models for thousands of repos, reflecting both technical depth and operational empathy.
