Staff Software Engineer, C++ (Patching)

About the role

We are hiring a Staff C++ Software Engineer to join our growing team developing NinjaOne’s automated endpoint management suite, 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.

The Patching team owns 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.

Responsibilities

• Review code for correctness, maintainability, and architectural health
• Mentor and guide senior and mid-level engineers on the team

• Translate roadmap priorities and customer needs into sound technical design
• Other duties as needed

Requirements

• Bachelor’s Degree in Computer Science, Engineering, Information Technology, or related technical field
• 10+ years of C++ development experience, with Modern C++ (C++17 and above)
• Cross-platform development experience (Windows/macOS/Linux – Win32 API, POSIX)
• Experience with gRPC / Protocol Buffers
• SQLite / Embedded database patterns
• CMake
• Proficiency working with Qt and Vcpkg a strong plus
