Role Overview

As a C++ Tech Lead on our Agent team, you’ll design, build, and optimize our real-time endpoint agent using modern C++ across Windows, Mac, and Linux environments (mostly Windows). You’ll collaborate closely with product, backend, and security teams to drive end-to-end feature development, leveraging deep OS internals knowledge to protect real-world customer environments.

Responsibilities

• Develop a real-time agent (written in C++) that collects massive amounts of data from endpoints, leveraging cutting-edge technologies, and getting familiar in-depth with the OS internals.
• Commit to full E2E feature development - from planning to automation.
• Design and develop solutions in collaboration with multiple dev teams.
  
  

• 7+ years of C++ software development experience, with a strong focus on systems-level programming.
• Strong expertise in object-oriented design, system design, and software architecture.
• Deep understanding and hands on experience of Windows, Linux, Mac and internals, including performance, memory management, and concurrency (Windows is a MUST!).
• Extensive experience with multi-threaded, multi-process, and high-performance systems.
• Hands-on experience developing complex client-server architectures at scale.
• Experience in designing and optimizing high-performance, low-latency systems.
• Ability to own large features or systems end-to-end, from design to production, including cross-team collaboration.
• Strong experience with debugging complex production issues and improving system reliability.
• Familiarity with build systems, CI/CD pipelines, and modern development workflows.
• Proven experience in leading technical initiatives or mentoring engineers (formal or informal leadership).
• Experience working in fast-paced, dynamic environments, with the ability to make technical decisions under ambiguity.
• Excellent communication skills, with the ability to align stakeholders and drive technical discussions.
• Experience in security or cybersecurity domains — a strong advantage.
