Description

About the Role

We are looking for a Senior Software Engineer, Java/Kotlin to join our Patching team, the team responsible for how NinjaOne discovers, packages, and deploys OS and third‑party software patches across every endpoint we manage.

React or Angular experience is a nice‑to‑have, you may occasionally touch UI components for the patching experience, but this is not a front‑end role. You'll work closely with the AI workflow, server, and platform teams, as well as product designers and product owners, to extend NinjaOne's patch management capabilities at scale.

We are flexible on remote working from home, if you are located in the USA and reside in one of the following states: CA, CO, CT, FL, GA, IL, KS, MA, MD, ME, NJ, NC, NY, OR, TN, TX, VA, OH and WA. We have physical offices in Austin, TX and Tampa, FL, if you prefer a hybrid option.
