- Develop and maintain malware configuration extractors (static and memory-based)
- Create, tune, and maintain YARA rules for detection and family tracking
- Perform low-level code analysis, unpacking, and de-obfuscation of protected binaries
- Use and interact with malware sandbox environments for dynamic analysis and triage
- Produce high-quality research publications,



technical reports, and threat intelligence write-ups
- Collaborate with other researchers to follow evolving threat actor techniques and infrastructure

What we’re looking for

- 5–6+ years of professional experience reversing Windows malware
- Strong hands-on experience analyzing stealers, ransomware, and trojan bankers
- Proven experience building config extractors via static analysis and in-memory parsing
- Strong working knowledge of IDA Pro (or equivalent tooling)
- Solid experience writing and maintaining YARA rules
- Experience with (or strong familiarity with) malware sandbox environments
- Demonstrated history of published malware research (blogs, whitepapers, conference talks, etc.)
- Excellent understanding of Windows internals and common anti-analysis techniques
- Proficiency in Python, C/C++, and Assembly
- Ability to work independently from initial triage to deep analysis on complex malware families
- Professional working proficiency in English

What’s offered

- Work on high-impact, real-world malware research
- A technically strong team of reverse engineers and threat researchers
- Opportunity to publish and gain visibility in the malware research community
- Competitive compensation commensurate with experience
