OT Cybersecurity Engineer

I’m supporting a well-funded cybersecurity company building technology specifically designed for industrial control system environments.

They’re winning work with organizations that need help improving security across operational technology networks, so they’re looking for engineers who are comfortable working inside live industrial environments - PLC networks, SCADA systems, DCS architectures, and Level 2/3 control networks.

This role combines hands-on OT security engineering with customer deployment work, helping organizations improve network security and architecture across industrial environments.

What the work looks like

• Designing and implementing security architecture within OT networks aligned to the Purdue model
• Working directly with PLC, SCADA, and DCS environments
• Implementing network segmentation, firewall rules, and secure zone/conduit architecture
• Supporting integration across industrial protocols and control system communications
• Investigating and troubleshooting issues across Level 2/3 industrial networks
• Automating operational tasks and deployments using Python, Ansible, or similar tooling
• Supporting customers as they modernize and secure legacy industrial infrastructure

Technologies and environments you’ll likely encounter:

Industrial protocols such as:

• Modbus / Modbus TCP
• OPC / OPC UA
• DNP3
• EtherNet/IP
• PROFINET

Security tooling used in OT environments such as:

• Dragos
• Claroty
• Tenable OT

What they’re looking for

• Experience securing industrial control systems (ICS) or OT networks
• Hands-on understanding of industrial network architecture
• Experience implementing segmentation, firewalls, and monitoring in OT environments
• Familiarity with SCADA, PLC, and plant network design
• Comfort working directly with operators, engineers, and plant stakeholders
• Someone who enjoys solving real problems in complex industrial environments
• Hybrid role based in Washington DC area
• Some travel to customer environments
• Compensation typically $175k–$200k + equity

This role suits engineers who prefer getting hands-on in industrial networks rather than writing policy, and who enjoy solving security challenges in environments where uptime and safety matter.

If that sounds like your kind of work, apply now for immediate consideration.
