About the Role

The Application Security Architect role is pivotal to the NinjaOne team, with company-wide visibility spanning individual developers through executive leadership. As part of NinjaOne's core Information Security organization, you will directly contribute to the security, privacy, reliability, and user experience of more than 6,000 customers across MSP and enterprise IT environments.

This is a highly technical, architecture-focused role blending hands-on software security and secure design principles. Ideally, you have a solid background in both software engineering and security. You will work across application, cloud, infrastructure, and identity layers to embed security into NinjaOne's software and systems from design through deployment.

Working closely with engineering, platform, and product teams, you will lead code reviews, secure design and architecture reviews, anticipate emerging threats, and help drive scalable, resilient, and compliant security solutions. You will also serve as a security mentor to engineering teams, helping raise overall security maturity across the organization.

Location - 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, OH, OR, TN, TX, VA, and WA. We have physical offices in Austin, TX and Tampa, FL, if you prefer a hybrid option.

*Onsite interviews may be required for this role.

We hire the best software engineers, but experience in our stack can’t hurt: NinjaOne is built on Java, Kotlin, C++, Golang and Postgres; supporting millions of user endpoints and running as a scalable cloud service in AWS. Knowing large-scale datastore bottlenecks, asynchronous application design and client-server architecture will help you.
