## About the role

As a Senior Backend Engineer on the Licensing, Usage & Entitlements team, you’ll build the services that determine what NodeZero customers have purchased, which capabilities are enabled for them, and how usage limits apply. You’ll own meaningful work across product packaging, entitlements, and usage workflows for direct and partner accounts. Because these systems affect customer access and downstream product behavior, you’ll focus on correctness, clear service contracts, and reliable operation. Found on 1752vc Careers, the job board for startup and VC roles.
