Overview

We need a Staff Security Engineer - Industrial Control Systems to design and implement practical compliance solutions enabling industrial automation equipment (PLCs, CNCs, Robots, HMIs, SCADA systems, Control Cabinets) to operate securely and reliably in a CMMC Level 2, ITAR-controlled environment with rich MES connection. This is a senior IC role. You will directly own compliance for critical defense-related production lines.

Responsibilities

• Compliant Production Line on Day 1— Take advantage of a greenfield build to land equipment that is compliant on Day 1
  

• Invent & implement solutions for the missing controls that let PLCs, CNCs, robots, HMIs, and SCADA join a CMMC Level 2 network on Day 1— no waivers, no delays.
  

• Author, own, and iterate a vendor-consumable spec (hardware, network, and procedures) that survives FAT, site acceptance, and yearly audits.
  

• Embed with vendors— drive design reviews, cabinet builds, and every FAT until the crate ships.
  

• Sustain compliance—automate patching, credential rotation, evidence collection, and CMMC artifact prep
  

• Deliver the outcome— leverage consultants or specialists to achieve the outcome as you see fit

Requirements

• Shipped at least one hardware + software security product that protects OT or critical infrastructure (network appliance, secure gateway, or similar).
  

• Hands-on with ICS/OT stacks: EtherNet/IP, Modbus/TCP, OPC UA, CNC file transfer, cabinet power/grounding, switch configs, industrial networking.
  

• Proven track record translating NIST 800-171/172 or CMMC L2 (in force 16 Dec 2024) into run-time controls
  

• U.S. Persons status
  

• 40% travel to vendor plants and FATs— no exceptions.

Bonus Requirements

• Systems-level engineering in C/C++, Rust, or Go on Linux-based platforms plus basic HDL/Firmware literacy.
