Multiple positions
1. THE MANDATE
Protocol Infrastructure is the standard-setting access governance layer for autonomous robotics in Commercial Real Estate (CRE). We do not manufacture robots. We map the physical and digital chokepoints of Tier-1 enterprise assets to establish the universal baseline for arbitration and fleet admission.
We are seeking a highly disciplined, freelance MEP Engineer or OT Field Technician to execute strictly governed, passive infrastructure audits inside flagship commercial high-rises. You will act as the independent, vendor-neutral auditor on behalf of Protocol Infrastructure. Approved engineers receive continuous, localized dispatch orders for asset audits as our portfolio scales.
2. EXECUTION SCOPE
You will execute the Protocol Audit alongside the facility’s Chief Engineer.
2.1 Strict Zero-Touch Mandate
