Fractional Security & Compliance Lead (IT & GRC)

About You

As a Fractional Security & Compliance Lead (20-40%) at Optiml, you will take full ownership of our security and compliance function. You’ll run our SOC 2 Type II and ISO 27001 programs end to end, coordinating audits, managing evidence and remediation, and ensuring controls stay effective as the company scales.

This is a hands-on role. You’ll administer and secure our internal IT and identity stack (Microsoft 365 / Entra ID, Google Workspace, access management, device provisioning), design and enforce RBAC and least-privilege access, and own onboarding and offboarding processes. You’ll also respond directly to enterprise customer security questionnaires, maintaining a clear, reusable knowledge base.

You’ll work closely with the CTO and Head of Operations but operate independently day to day, with flexibility around hours and workload. We’re looking for someone who has done this before—who can move quickly, automate where possible, and treat security as a practical enabler for the business, not a checkbox exercise.
