We are seeking an experienced Rail Systems / SCADA Cybersecurity Engineer to support a cybersecurity assessment of Operational Technology (OT), Industrial Control Systems (ICS), and Supervisory Control and Data Acquisition (SCADA) systems within a light rail/transit environment.

This is a part-time contract position for a professional with experience in rail, transit, SCADA, OT/ICS, or comparable critical infrastructure environments. The selected candidate will work alongside cybersecurity, engineering, operations, safety, and project management professionals to assess safety-critical operational systems using non-disruptive methodologies appropriate for live rail and SCADA environments.

Job Type: Part-Time, Contract

Project Duration: 3-6 months

Expected Timeframe: (October 2026 – March 2027), TBD; Part-Time Project Based

Location: St. Louis, Missouri (Hybrid/Onsite as Required)

Schedule: Variable based on project requirements

On-site Requirement: Primarily remote with scheduled onsite activities as required

Location & Onsite Availability

Preference will be given to candidates located in or near the St. Louis Metropolitan area who can reasonably travel to project facilities for stakeholder meetings, field assessments, system walkthroughs, technical reviews, and other authorized onsite activities.

Candidates located elsewhere in Missouri may also be considered if they are available to travel to the St. Louis area as project requirements dictate.

Key Responsibilities

• Support cybersecurity assessments of rail OT, ICS, and SCADA systems using non-disruptive methodologies.
• Assess critical rail systems, including Operations Control Centers (OCCs), traction power, substations, wayside train control, signals, switches, and crossings.
• Review and validate OT/SCADA asset inventories, field devices, network equipment, communications infrastructure, and system interfaces.
• Evaluate OT network architecture, segmentation, industrial communications, system dependencies, and IT/OT interfaces.
• Assess cybersecurity controls related to access management, remote connectivity, configurations, monitoring, logging, patching, and firmware management.
• Review interfaces with supporting systems, including PA/CIS, CCTV, physical access control, vendor remote access, and enterprise IT.
• Support threat modeling, cybersecurity risk assessments, and safety-impact analysis, considering system criticality, operational impact, availability, and reliability.
• Contribute to technical findings, remediation recommendations, network/segmentation documentation, risk assessments, and project reports.
• Coordinate with cybersecurity, engineering, operations, safety, and maintenance stakeholders while ensuring activities comply with approved Rules of Engagement and do not disrupt live or safety-critical systems.

Required Qualifications

• Professional experience with rail, transit, SCADA, OT/ICS, or comparable critical infrastructure systems.
• Strong knowledge of SCADA architecture, industrial networks, field devices, communications systems, and OT network segmentation.
• Experience with cybersecurity assessments and non-disruptive methodologies in live OT/SCADA environments.
• Ability to interpret network diagrams, system architectures, asset inventories, and technical configurations.
• Strong analytical, technical documentation, communication, and collaboration skills.
• St. Louis-area or Missouri-based candidates strongly preferred, with availability for scheduled onsite activities in the St. Louis metropolitan area.

Preferred Qualifications

• Direct experience with rail, light rail, passenger transit, or similar transportation systems.
• Experience with SCADA, Operations Control Centers (OCCs), traction power, rail signaling, wayside systems, or industrial communications networks.
• Experience conducting cybersecurity assessments in live OT/ICS or safety-critical environments.
• Familiarity with NIST CSF, NIST SP 800-82, ISA/IEC 62443, TSA, FTA, or State Safety Oversight requirements.
