About The Position

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. The Junior OT/ICS Lab Engineer is a hands-on technical role supporting the design, build, testing, and validation of operational technology environments. You will work alongside senior engineers to create realistic OT lab systems, test Dragos detection and response capabilities, validate platform performance, and support threat research activities. This role combines hands-on engineering work with exposure to real-world OT protocols, devices, and operational scenarios.

Requirements

Strong foundation in networking: OSI model, TCP/IP, subnetting, routing, firewalls, and network protocols
Hands-on experience building or working with lab/test environments; familiarity with virtualization platforms (VMware, Hyper-V, KVM) or containerization
Basic understanding of IT infrastructure and security concepts
Comfortability working at the command line (Linux/Windows); scripting skills (Python, Bash, PowerShell) a plus
Ability to follow technical documentation, troubleshoot systematically, and ask clarifying questions
Willingness to learn OT-specific protocols and operational technology fundamentals
Ability to perform basic fabrication and panel building, including mounting/installing panels to engineering drawings and wiring devices and components. Welding, instrument fitting, and conduit work are not required for this role

Nice To Haves

Familiarity with industrial protocols (Modbus, Ethernet/IP, Profibus, DNP3) or SCADA/HMI systems
Experience with network packet analysis tools (Wireshark, tcpdump) or protocol decoding
Practical experience with PLCs, industrial IoT devices, or control system engineering
Experience with electrical troubleshooting (e.g., diagnosing circuits, relays, control wiring) is a plus
Security certifications (Security+, CEH, GCIA) or cybersecurity coursework
Experience in critical infrastructure or manufacturing environments
Familiarity with ICS security frameworks (NIST, NERC CIP, IEC 62443)
Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or related technical Engineering field (or equivalent practical experience)

Responsibilities

Build, configure, and maintain lab environments that simulate real OT operational scenarios
Set up and manage industrial control systems (PLCs, RTUs, HMIs) and networked industrial devices
Deploy sensors, data collection tools, and monitoring infrastructure to capture OT network traffic and telemetry
Document lab configurations, system topologies, and operational procedures for team reference
Execute test plans to validate Dragos platform capabilities against simulated OT threats and normal operational activity
Collect network traffic, device behavior, and telemetry data from lab systems to support research and product development
Assist in reproducing reported issues or edge cases in a controlled lab environment
Participate in threat scenario development and validation exercises
Troubleshoot lab infrastructure issues, network connectivity problems, and device configuration challenges
Support internal and external teams requiring access to OT lab resources for research, testing, or validation
Contribute to lab documentation, runbooks, and training materials for team onboarding
