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.

About Optiml

Optiml is revolutionizing real estate with our Real Estate Decision Intelligence (REDI) software—a new class of decision technology that embeds AI to help decarbonize buildings while optimizing asset financial performance.

We are an ETH Zurich spin-off that launched our first product in April 2024 and are now scaling across Europe and the US. We recently raised an oversubscribed €8M Seed round to accelerate our growth, supported by leading VCs such as KOMPAS, Planet A Ventures, Innovation Endeavors (the fund of former Google CEO Eric Schmidt), BitStone Capital, and The Bau Ventures, along with leading angels.

Built on more than a decade of research and proprietary IP, our platform enables institutional investors, owners, and asset managers to make underwritable, forward-looking decisions across the full asset lifecycle — from acquisition to exit — replacing static, backward-looking reports with actionable intelligence.

Trusted by leading organizations across Europe and beyond, Optiml supports capital allocation decisions that balance key financial, regulatory, and sustainable considerations under real-world constraints.

As of early 2026, we are expanding our team to scale our product capabilities and operational delivery as we work to make Real Estate Decision Intelligence the global standard for real estate investment decision-making.
