Software Engineer, C++ (Patching

About the Role

We are hiring a Staff C++ Software Engineer to join our growing team developing Ninja One’s automated endpoint management suite of software products, trusted by over 40,000 customers globally. You will develop high‑impact software products used daily by IT teams and MSPs (managed service providers) to monitor, manage, and secure endpoints at scale.

You’ll collaborate in a fast‑paced, agile environment that emphasizes rapid iteration and customer‑driven outcomes, working alongside other Software Engineers, Product Designers, and Product Managers. You are responsible for implementing design patterns and working on enterprise‑level software challenges in a startup environment, enabling firsthand product impact, while building software of scale that runs on millions of endpoints.

Patching engineers own the full lifecycle of keeping endpoints up‑to‑date, from detecting available patches to safely applying them and rebooting. The work spans OS patches across multiple platforms (Windows Update, macOS software update, Linux package managers) and third‑party application updates (3PP).

As a Staff Engineer on this team, you’ll work on our C++ agent repo — the software that runs directly on customer devices with elevated system privileges to detect, install, and validate patches across Windows, macOS, and Linux. This means working close to the metal with system‑level APIs, building resilient install and rollback logic, and reading and acting on policy owned by our mainline platform team.

You’ll be one of the most senior technical voices on the C++ side of Patching, helping shape architecture and mentoring other engineers as the team continues to grow.

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, and WA. We have physical offices in Austin, TX and Tampa, FL, if you prefer a hybrid option.

• Other duties as needed

• Bachelor’s Degree in Computer Science, Engineering, Information Technology, or related technical field
