Job description

About the Role

We are hiring a Senior 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 rely on to monitor, manage, and secure endpoints at scale.

You will 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 and millions of endpoints.

If you are a Senior Software Engineer with application‑level C++ expertise, 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.

What You’ll Be Doing

• 7+ years of C++ development experience, with proficiency in C++14 or newer
• 5+ years of Windows systems‑level C++ engineering
• Strong familiarity with Windows kernel drivers
• Experience designing or maintaining a Windows kernel‑mode driver or service that runs on production endpoints
• Comfortable designing from first principles; this is a net‑new system with no existing internal architecture to inherit
• Drive technical design: write architecture documents, define subsystem contracts, work cross‑functionally with server and UI engineers
• Comfortable working on problems with sparse documentation and undefined requirements
• Comfortable experimenting with AI tools in development workflow

Preferred

• WHQL driver certification experience (strongly preferred)
• Driver development background (minifilter, WFP)
• macOS systems experience: Apple Endpoint Security framework
• Linux systems experience: eBPF or kernel module development
