Location: Plainsboro, NJ
Duration: 12 Months Contract
Job Description
We are seeking a high-caliber Network Cybersecurity Analyst with proven experience defending complex, hybrid enterprise networks. This role requires deep packet-level expertise, strong incident response skills, and the ability to engineer threat detections — not just triage alerts.
You will hunt, detect, contain, and respond to sophisticated adversaries while continuously improving our defensive posture.
Key Responsibilities
- Perform advanced network threat detection, triage, and analysis using PCAP tools (Wireshark, Tcpdump)
- Build custom detection signatures and rules (Snort, Suricata, Zeek)
- Engineer and optimize SIEM detections and correlation logic (Splunk SPL, KQL, QRadar)
- Conduct proactive threat hunting aligned to MITRE ATT&CK techniques
- Lead incident response including containment, forensic evidence collection, eradication, and recovery
- Automate log enrichment, IOC extraction, and response workflows with Python or PowerShell
- Monitor and protect on-prem, cloud, and hybrid environments
- Develop and maintain runbooks and SOAR playbooks
- Provide detailed written reports for leadership, compliance, and audit teams
- Collaborate with network engineering, DevSecOps, and cloud security to eliminate vulnerabilities
Required Technical Expertise
- Strong command of TCP/IP, DNS, TLS, HTTP, SMB, and deep understanding of L4–L7 protocol behavior
- Hands-on experience with:
- IDS/IPS tuning and rule authoring
- NDR tooling (Darktrace, Vectra, Corelight)
- SIEM engineering: parser creation, dashboards, custom detection logic
- Memory and endpoint forensics (Volatility, EDR tooling)
- Strong experience with cloud detection:
- Threat intelligence operationalization — mapping TTPs to real detections
- Familiarity with Zero Trust network security models
