C++ Software Engineer | Endpoint State & Control

NinjaOne is hiring a C++ Software Engineer for its Endpoint State and Control team. The role focuses on building testing infrastructure and coverage for C++ systems, then contributing to feature development for software that defines and enforces endpoint behavior and security posture.

Responsibilities:

• Testing Ownership: You will begin by building and owning the testing infrastructure and test coverage for two systems, both active C++ development projects
• Feature Development: With your strong C++ fundamentals, a genuine interest in systems-level software, being curious in a domain where many answers don’t yet exist, you will begin to take on feature development contributions for our development projects
• Other Duties as needed

Requirements:

• Bachelor's Degree in Computer Science, Engineering, Information Technology, or related technical field
• 1–3 years of C++ experience
• Solid C++ fundamentals: memory management, RAII, STL, smart pointers, build systems (CMake preferred)
• Interest in systems-level software: OS APIs, processes, file systems, services — understanding what software "beneath the app" does
• Experience writing or maintaining automated tests in C++ (Google Test, Catch2, CTest, or equivalent)
• Comfortable asking questions and working in an environment where some answers are still being discovered
• Comfortable adapting workflows to incorporate AI tools
• Strong learning orientation - ability to ramp on new systems, APIs, and patterns through documentation, code reading, and mentorship
• This position is NOT eligible for Visa sponsorship
• Any Windows systems programming exposure: Windows APIs, WINAPI, WinBase, Registry access, process management - even if self-taught or project-based
• Familiarity with CMake + vcpkg build environments
• Experience with test frameworks that support mocking or dependency injection (Google Mock, etc.)
• Any exposure to cross-platform C++ (code that compiles on Windows AND macOS or Linux)
• Background in or genuine interest in security software (endpoint protection, antivirus, system hardening)
• Exposure to ctest or structured CI test pipelines
• Knowing large-scale datastore bottlenecks, asynchronous application design and client-server architecture will help you
