A day in the life of an OnGuard Cloud Team Member

If you thrive in an environment where every day is different, OnGuard Cloud is that team: engineers switch between onboarding projects, automation design, troubleshooting, and collaboration with internal and customer teams.

We help customers reduce technical debt by replacing legacy on-premises access control servers and migrating them to the AWS-hosted OnGuard Cloud Access Control System.

Our team fully manages the customer's OnGuard application, the OnGuard infrastructure, and the underlying AWS environment to ensure high availability and strong cybersecurity.

We onboard both existing OnGuard customers and "greenfield" customers who are new to the platform, which makes every onboarding project unique.

We support the latest OnGuard versions, so customers benefit from improved availability, performance, quality, and newly released features.

Engineers on this team design new automated solutions and enhance monitoring of access control systems. The team works from a robust backlog of features and user stories to improve shared processes with internal Honeywell teams (for example, automated certificate rotation), our automation platforms, and our customers.
