Senior Low-Level C++ Engineer

🚀 Senior Low-Level C++ Engineer | Cybersecurity | Core Team (Stealth Startup)

We’re building something rare: an endpoint security product designed for the real world — where attackers are creative, fast, and persistent.

If you enjoy going deep into how operating systems actually behave (not how we wish they behaved), and you like turning that knowledge into high-performance, production-grade defense, this one’s for you.

What you’ll work on

• Modern C++ (C++17/20) components running across Windows/Linux/macOS
• OS internals: processes, memory, filesystems, networking, IPC
• Multithreaded, performance-critical code (correctness and speed matter)
• Building defense that stands up to real attacker techniques — not theory
• Core architecture decisions, code reviews, and technical ownership

What we’re looking for

• 5+ years hands-on modern C++
• Strong low-level / systems background
• Solid multithreading & synchronization experience
• Experience with OS-level APIs and cross-platform development
• Cybersecurity mindset (endpoint / EDR / security products / RE / vuln research) is a big plus
• Bonus: OS hardening, fuzzing, exploit mitigations, firmware/hypervisor, DFIR/malware

Why join

• Stealth, well-funded, and moving fast
• You’ll be part of the founding/core team with real ownership
• A technically deep problem space where great engineering actually matters
