SenseOn • London, UK • 1d ago

At SenseOn, we're revolutionizing cyber defense with our next-generation XDR platform. Our technology is redefining how organizations detect and respond to threats by unifying endpoint and network visibility with advanced behavioral analytics. We process security telemetry at scale, transforming vast amounts of raw data into actionable intelligence in real-time.

We're not just another security company - we're a fast-growing, fast-moving team tackling some of the most complex challenges in cybersecurity. Our engineering culture values technical excellence, continuous learning, and the thrill of solving hard problems that make a real difference in protecting organizations worldwide.

The role:

As a C++ Engineer, you'll be part of our systems engineering team that tackles both endpoint and backend challenges. You'll work on our Universal Sensor technology, developing our cross-platform security agent, while also building high-performance backend systems that process millions of security events per second. Our C++ codebase spans from low-level system interactions to highly optimized data processing pipelines, offering a unique opportunity to work across the full security stack.

What you'll do:

Build critical components in modern C++ (17/20) across both endpoint and backend systems
Develop high-throughput data processing pipelines that handle millions of security events per second
Dive deep into system internals to implement stealthy and efficient security monitoring capabilities
Design and optimize concurrent systems that maintain performance under heavy load
Work with Windows, Mac and Linux endpoints, from kernel-level monitoring to userspace applications
Collaborate with our threat research team to implement novel detection techniques that catch real-world attacks
Work in small, focused teams using modern development practices (CI/CD, code review, automated testing)
