Role summary

The Senior OT Security Analyst will lead a frontline monitoring and triage unit focused on identifying adversary activity within customer operational technology (OT) environments. Responsibilities include investigating network anomalies, validating detections, mentoring junior analysts, and operating the Dragos platform for customers. The role requires strong networking and security monitoring skills, with a focus on industrial cybersecurity. The analyst will escalate findings, tune detection logic, and provide clear incident summaries. This is a remote position with flexible shift options, including on-call duties.

At Dragos, the mission is personal. The systems we protect deliver the water you drink, power your home, and keep the hospitals your community depends on running. Those critical infrastructure systems that power our civilization around the world are under attack every day by adversaries. When those systems fail, people are immediately at risk. We are the global leader in xOT cybersecurity, combining technology, threat intelligence, and expert services. The people here chose this work because they understand what is at stake. Here, you will find a remote-first mission-driven team across North America, Europe, the Middle East, and APAC built on authenticity, transparency, and trust. If safeguarding the systems that protect your family, friends, and community is the kind of work that matters to you, you are in the right place.

About the Role:

As a Senior OT Security Analyst on the OT Watch Complete team, you will help lead a frontline monitoring and triage unit responsible for identifying potential adversary activity in customer operational technology (OT) environments. You will work closely with other experienced industrial defenders and mentor junior analysts to investigate anomalous network behaviors, validate detection triggers, and support threat hunters and incident responders with high-quality escalations. You will also operate and maintain the Dragos platform on behalf of customers, helping manage vulnerabilities, tune detections, properly classify OT assets, and provide input on response recommendations. This is a great opportunity for experienced cybersecurity professionals — especially those passionate about industrial security — to build hands-on experience in active OT security operations.

Responsibilities:

  • Lead shift operations, guiding analysts as they triage detection alerts and network telemetry from the Dragos Platform across customer OT environments — stepping in as shift leader for your region when needed.
  • Serve as a senior investigator, digging into suspicious activity to identify misconfigurations, anomalies, and potential malicious behavior across industrial networks.
  • Apply deep analysis and context to escalate findings to Incident Responders and threat hunters with clear, actionable documentation.
  • Partner across teams — analysts, threat hunters, incident responders, platform engineers, and Detection Engineering — to tune detection logic, reduce false positives, and shape new Dragos Platform detections and playbooks.
  • Write and deliver incident summaries and operational reports that give internal stakeholders and customers a clear read on what's happening in their environment.
  • Support the full scope of OT Watch Complete, from asset classification and vulnerability management to hardening recommendations and direct customer information requests.
  • Build expertise continuously in ICS/OT protocols, adversary tradecraft, and threat intelligence specific to industrial environments.

    • Qualifications:

  • 3–5 years of experience in network security, ideally with hands-on exposure to real-world threat investigation.
  • Solid understanding of core networking concepts — TCP/IP, firewalls, DNS, packet analysis.
  • Hands-on experience with security monitoring tools, such as IDS/IPS, SIEM platforms, or network traffic analyzers.
  • Strong written and verbal communication skills, with close attention to detail — you'll be translating technical findings for both internal teams and customers.
  • Genuine interest in ICS/OT cybersecurity and a drive to defend critical infrastructure, paired with the ability to pick up complex, industrial-specific concepts quickly and apply them.
  • Comfortable working independently in a remote environment while coordinating across distributed teams.
  • Flexibility to participate in shift-based coverage and occasional weekend/on-call work as needed. Note: The initial schedule will be Monday-Friday 8am-5pm, with on-call weekends (MDT for US, CEST for Europe, AEST for AUS). The schedule will later change to a 4 day/week, 10 hour shift model, which includes a day on the weekend. Shift schedules under the 4-day schedule will run Sunday-Wednesday and Wednesday-Saturday. Applicants will have the option to pick from either of the two shift schedules (Sunday-Wednesday or Wednesday-Saturday).

    • Preferred Qualifications:

  • Experience working on a Security Operations Center (SOC) team.
  • Familiarity with OT protocols (e.g., Modbus, DNP3, Ethernet/IP) and ICS environments.
  • Applied knowledge of adversary tactics and frameworks relevant to OT (e.g., MITRE ATT&CK for ICS).
  • Hands-on lab or internship experience in cybersecurity operations, threat hunting, or digital forensics.
  • Experience in packet capture (PCAP) analysis or basic scripting (e.g., Python, Bash).

    • Compensation:

  • Salary: $110,000
  • Competitive Equity Package
  • Comprehensive Benefits Plan
