As a Rapid7 MDR Senior Detection and Response Analyst, you are a subject matter expert in the operations of the Rapid7 Managed Detection and Response Security Operations Center. You excel at conducting alert triage and investigation, forensic artifact analysis, and using the tools at your disposal to get the answers you need with the data you have. And, if you do not have that data, you know who to ask and what to ask for to get it. You will participate in incident response engagements and prepare professionally written client deliverables, and speak to clients about the deliverables. You are continuously reviewing operational processes for improvement, and are not afraid to be the change needed to improve them. You will seek mentoring opportunities for other analysts, and impart your knowledge to the SOC at large, when needed. 

About the Team

Rapid7’s Managed Detection and Response (MDR) team brings passionate security talent face to face with emerging threats and real-world challenges. Operating 24/7/365, MDR combines monitoring, threat hunting, and incident response with an impact-driven mindset that encourages innovation and effective solutions.

Within MDR, the Tactical Operations (TACOPS) team manages the most time-critical investigations using InsightIDR, Rapid7’s cloud-hosted SIEM. TACOPS analysts handle investigations end-to-end—from alert triage to incident report delivery—covering everything from account compromises and malware to web server breaches and zero-day exploits.

You’ll collaborate closely with Customer Advisors, who manage communications, allowing you to focus on analysis. When cases escalate, you’ll support Rapid7’s Incident Response team by analyzing log data or forensic artifacts. You’ll also act as a technical escalation point for junior analysts, contribute to training, and occasionally join customer meetings to review workflows or incident findings.

We’re looking for someone skilled in investigative methods, log and forensic analysis, and eager to keep learning. You’ll be supported by your team lead and peers as you grow your expertise and career—whether toward roles in Incident Response, Threat Hunting, or advanced SOC analysis.

This position follows a hybrid schedule, requiring at least three days in the office, including Wednesdays for the TACOPS shift handover.

• Prepare Incident Reports for each investigation you complete, which follows MITRE’s ATT&CK Framework and includes your own forensic, malware, and root-cause analysis.

• Serve as a technical escalation point for the junior analysts in your team

• Be fully confident with entire tech stack the SOC uses on a day to day basis; training and enablement will be provided for external hires

• Work with leads or managers to continually update the SOC’s training and enablement

• Participate on - and lead some - projects to improve the MDR service

• Engage with customers as necessary to discuss incidents and speak to how an analyst triages and investigates alerts

• Work towards becoming an expert in a subject relating to the SOC day-to-day, such as Windows registry forensic artifacts   

The skills you’ll bring include:

• 3-5 years of experience in a cybersecurity related position (SOC and/or SIEM analysis experience preferred)

• Thorough understanding of investigative methodology and the incident response lifecycle, cyber killchain, etc.

  • Knowing what questions need to be answered and how to pivot to get them  to conduct an investigation and provide customers with the recommendations they need to contain, remediate, and eradicate threats from their environment

  • Includes thorough understanding of how threat actors utilize tactics such as lateral movement, privilege escalation, defense evasion, persistence, command and control, and exfiltration. 

• Excellent verbal and written communication skills 

• Familiarity with NTFS, FAT32, APFS and/or Ext* filesystems.

• Basic understanding of memory forensics 

• Demonstrable knowledge of analysis of Windows, Linux, and/or Mac forensic artifacts.

  • Demonstrated through day-to-day work (internal hire) or a technical interview panel (external hire) 

• Existing experience assisting with customer escalations/calls 

• Complete familiarity with the Rapid7 tooling used by the SOC (external hires will receive enablement

• Experience handling Incident Response engagements conducted by an Incident Response team

• Be capable of prioritizing and managing your time to ensure the best possible outcomes for the MDR service and its customers
