  • Threat hunting and forensic analysis. You will devise hunt hypotheses, creatively find new and unusual threats, and will confirm the reach of threats identified by the front line.
  • You will test existing detection logic for gaps and faulty assumptions, creatively identifying ways adversaries might evade detection, and then come up with solutions.
  • Provide expert threat analysis support to CSIRT and Global SOC. Research actors and tactics, identify ways for SOC to detect and CSIRT to contain a threat in real-time. Research anomalies detected by SOC to assess whether threat or benign.
  • Produce threat reports tailored to Marvell business and distributed to the relevant stakeholders throughout the company; in varying forms from real-time immediate action to in-depth periodic assessments of trends and future expectations.
  • When required, provide real-time and expert threat investigation support to the global Cyber Security Incident Response Team.
  • Collaborate with the SIEM and SOAR engineering teams as well as SOC to turn hunting hypotheses into production detection cases and response playbooks.

  • 15+ years' experience in one or more security-relevant domains including 10+ years as a SOC Analyst, or a Network Analyst with security scope; preferably for a >5000 person enterprise.
  • Experience in working with a geographically diverse team in multiple time zones around the globe
  • Strong communication skills and an ability to adapt a message to audiences ranging from technology SMEs to company executives to stakeholders in every business discipline.

  • Proficiency in common scripting languages such as PowerShell, Bash, Python, etc.
  • Proficiency with one or more SIEM query language
