Manage devices and everything they touch. See how security, IT, and compliance get easier when unified around devices with Iru. Backed by General Catalyst and Felicis.
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
