C++ Software Engineer | Endpoint State & Control

About the Role

We are hiring a C++ Software Engineer to join our growing Endpoint State and Control team, focused on defining and enforcing endpoint behavior across a managed environment. We build the foundational controls that let IT teams define, enforce, and maintain a strong security posture across every endpoint they manage. Trusted by over 40,000 customers globally, your work will directly power the tools IT teams and MSPs (managed service providers) rely on to monitor, manage, and secure endpoints at scale.

If you are Software Engineer with strong C++ fundamentals and a genuine interest in systems-level software, who thrives on solving complex technical challenges and is passionate about building high-quality, reliable software for real-world impact, this is the role for you!

• 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

• 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

• Any Windows systems programming exposure:
  Windows APIs, WINAPI, Win Base,

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
