Role summary

Dragos is hiring a Senior Detection Engineer to develop high-fidelity threat detections for OT environments. This role involves analyzing threat intelligence, creating ICS-focused detections, and mentoring junior engineers. Responsibilities include testing and validating detections, managing detection requests, documenting processes, and analyzing ICS artifacts. The ideal candidate has 8+ years in security operations or offensive roles, 2+ years operationalizing threat intelligence, and 1+ year in ICS environments. Strong skills in network packet analysis, Windows logging, and OS internals are required. Preferred qualifications include experience with detection technologies like Suricata/Snort, programming languages like Python, and SOC platforms like Splunk/Elasticsearch.

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:

Dragos is seeking a Senior Detection Engineer to join our Detection Engineering team, which plays a pivotal role in our customers' ability to identify and respond to threats targeting their OT environments by turning cyber threat intelligence into high-fidelity, performant detections. Backed by the industry’s largest and most experienced team of industrial control systems (ICS) cybersecurity practitioners, Dragos ICS Cyber Threat Intelligence provides in-depth visibility of threats targeting industrial environments globally. As emerging threats to ICS environments are identified, the Detection team studies those threat behaviors and creates atomic, component, and composite detections for the Dragos Platform. To be successful at Dragos you will need to:

Be self-motivated, persistent, and creative in the face of complex technical challenges.

Align with the thought process of a cyber adversary and the ICS Cyber Kill Chain to predict the desired outcome of an attack.

Be a team player on a fast-moving team focused on rapidly innovating the state of industrial security.

Openly share information at every opportunity to enhance the knowledge of your team.

Continuously invest in and expand your knowledge of ICS technologies.

At Dragos, we don’t hire engineers whose only mission in life is to write detection rules. We are looking for detection engineers who yearn to contribute to more than just an analytic portfolio and who are willing to stretch themselves to accomplish the mission.

Responsibilities:

Create ICS-focused threat detections (atomic, component, composite, and events) and Asset Identification analytics based on assigned tickets.

Mentor Detection Engineers by engaging them in your detection development process and delegating portions of detection development they are ready to own.

Engage with Principal Detection Engineers to support their detection development initiatives through analysis of packet captures and Windows host logs.

Test, validate, and tune detections created by the Intel Detection team, including rules submitted by trusted advisors and industry partners, for analytic quality control.

Lead the review, triage, and response for detection requests submitted to the Intel Detection Support board, enriching tickets with PCAPs, links, tags, and documentation.

Drive documentation of processes for authoring, validating, and testing analytics released in Dragos Platform Knowledge Packs (KPs), and keep the knowledgebase current on reported issues, false positives, and detection questions.

Analyze artifacts collected from ICS equipment, embedded devices, firewalls, network devices, and ICS software, and support staging and artifact collection within the Dragos ICS Cyber Range.

Analyze cyber threat intelligence reporting to create detection ideation tasks for threat behavior-based detections and Asset Identification.

Partner with the Engineering, OT Watch, and Quality Engineering teams to identify protocol coverage gaps and resolve detection issues in the Dragos Platform.

Give and receive peer feedback on a normal cadence as part of our review cycle.

Qualifications:

Required:

8+ years in security operations, threat hunting, or detection development, OR offensive operations, threat emulation, or security tool development

2+ years of experience operationalizing cyber threat intelligence to defend networks from emerging threats

1+ years of direct experience with SCADA, DCS, building automation, or other industrial control system devices and environments

Advanced network packet analysis and manipulation using tools such as Wireshark, Tshark, ngrep, tcpdump, Zeek, and Scapy

Working knowledge of Windows Event Logging fundamentals, including enabling and reviewing event logs, adjusting log size and retention settings, and enabling Advanced Audit Policies

Awareness of common operating system internals and the ability to identify analytic opportunities

Comfortable working with multi-gigabyte host and network datasets

Applied knowledge of network communication fundamentals

Proven ability to mentor and develop junior detection engineers

Adept at both verbal presentation and technical writing

Preferred:

Experience creating detections using technologies such as Suricata, Snort, YARA, or Zeek

Prior experience producing cyber threat intelligence reports or working with threat intelligence to understand and counter adversary operations

Development experience with programming languages such as Python, Rust, Ruby, Go, or Lua

Experience with SOC platforms such as Splunk or Elasticsearch (including the ECS schema)

Experience incorporating AI tools, models, or services into detection engineering workflows

Prior experience with ICS network assessments or ICS penetration testing

Windows and Linux system administration, networking and firewalls, and virtualization experience

Cybersecurity certifications such as SANS GICSP, GRID, GCTI, GCIA, GCIH, or GCDA; Offensive Security OSCP, OSEP, or OSED; CompTIA CySA+ or PenTest+; or similar

Ability to travel (less than 10%) for internal team activities, conferences, and customer sites to collect and analyze data

Compensation:

Salary: $152,000
