* from anywhere within the U.S. as you take on some tough challenges.

• Monitor and analyze emerging cyber threats, threat actor tactics, techniques, and procedures (TTPs), third-party incidents, and vulnerabilities relevant to the organization
• Evaluate intelligence sources and distinguish reliable technical evidence from unverified reporting or low-confidence attribution
• Perform technical analysis of malicious infrastructure, IP addresses, domains, URLs, certificates, and email artifacts using passive DNS, WHOIS/RDAP, and internet scanning data
• Analyze malware and suspicious files using static/dynamic analysis techniques, sandbox environments, and reverse-engineering tools as appropriate
• Produce clear technical intelligence reports, briefings, and profiles detailing adversary capabilities, confidence levels, and recommended defensive actions
• Partner with Security Operations, Threat Hunting, Incident Response, and Vulnerability Management teams to enrich telemetry, develop hunting queries, and provide adversary context
