## About the role

We are looking for a Security Researcher focused on detection engineering for Windows and macOS to join our small, focused Threat Intelligence and Research team. You’ll own detections end to end: researching adversary behavior, turning that research into file-based and behavioral detection logic, validating it, and shipping it into our EDR product. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Proven track record building file-based and behavioral detections for endpoints (YARA, Sigma) and shipping them into a product or production environment
- Experience taking a detection from research through testing and release, and maintaining it over time as adversary behavior changes
- Strong understanding of OS internals and endpoint security mechanisms on Windows and macOS (ETW and kernel callbacks, Endpoint Security APIs), and of the telemetry they produce
- Working knowledge of adversary tradecraft and detection coverage frameworks (MITRE ATT&CK)
- Experience with malware analysis tools and techniques (Binary Ninja, Ghidra, IDA, WinDbg, Sysinternals, or Mac Monitor)
- Experience hunting with threat intelligence platforms (VirusTotal, Google Threat Intelligence, or equivalent), including retrohunting and hunting rule development
