About CINC Systems

CINC Systems is the leading provider of accounting and management software for the community association management industry. Our platform powers tens of thousands of associations and millions of homes through secure, reliable, and increasingly intelligent software systems.

We are evolving our platform into an AI enabled ecosystem that combines modern SaaS architecture, operational workflows, communications, payments, analytics, and automation into a unified customer experience. This transformation requires engineers who are equally comfortable designing enterprise systems, working directly with business workflows, and leveraging AI to accelerate software development and product capabilities.

The systems we build are increasingly interconnected and AI enabled. Success in this environment requires more than coding ability alone. It requires judgment, systems thinking, customer understanding, and the ability to integrate modern AI capabilities into practical enterprise software.

Role Overview

We are looking for a highly technical Security Engineer with deep experience across application security, AWS cloud security, offensive security, secure SDLC, threat modeling and AI security.
