Peraton Labs is hiring a Senior OT Cybersecurity / ICs Security Architect - a part-time, midcareer-to-senior systems architect role bridging operational technology (OT), industrial control systems (ICS), and enterprise IT cybersecurity - to join our Strategic Innovation Group in support of a federal customer's cybersecurity and OT modernization program for critical infrastructure.

This is a part-time engagement (approximately 20 hours per week, schedule flexible around program milestones) suited to an experienced professional seeking a focused, high-impact engagement without a full-time commitment.

As a Senior OT Cybersecurity / ICs Security Architect on our team, you will contribute to the requirements and solutions-analysis effort for one or more parallel work streams of the customer's modernization program, spanning core capability areas such as access control, security monitoring, and asset and vulnerability management. You will work with the customer's engineering, operations, cybersecurity, and test-and-evaluation stakeholders, alongside a Peraton Labs delivery team of engineers and technical writers.

The goal is to define requirements, survey the market, evaluate candidate products, and deliver defensible recommendations that guide the customer's procurement decisions.

• Contribute to end-to-end solutions analysis for one or more work streams: elicit and validate requirements, and help produce System Requirements Specifications (SRS) with traceability to NERC CIP, FISMA, and CISA Zero Trust Architecture.
• Support market research to identify candidate commercial products across identity and access controls, network monitoring and threat visibility, and inventory / configuration / vulnerability management.
• Help draft Requests for Information (RFIs), review vendor responses, and participate in technical engagement with bidders under federal market-research guardrails.
• Assess vendor responses and product capabilities against requirements; contribute to comparison reports and down-select recommendations.
• Contribute to lab test environment design and test plans; observe or participate in hands-on product demonstrations and evaluation at customer and Peraton Labs facilities.
• Co-author Alternative Solutions Analysis (ASA) documents and support steering-committee and executive briefings.
• Bring lived-experience perspective from a federal hydropower-marketing / multi-regional transmission operator to workshops that align requirements across operational technology (SCADA, EMS, RTUs, protective relays, industrial protocols) and enterprise IT cybersecurity domains.

• U.S. Citizenship and the ability to obtain and maintain a Public Trust determination and PIV credential for unescorted access to the customer facility.
• Bachelor's degree in Computer Science, Computer or Electrical Engineering, Cybersecurity, or a related technical discipline, and 8+ years of progressive systems architecture, cyber engineering, or grid operations engineering experience; in lieu of a degree, 12 years of relevant experience will be considered.
• Demonstrated hands-on experience across both operational technology (OT / ICs) and enterprise information technology (IT) security environments.
• Direct hands-on experience delivering OT / ICs cybersecurity work inside a bulk-electric-system operating environment, as a full-time technical contributor accountable for production operations - not solely as an external consultant.
• Hands-on experience applying NERC CIP standards (CIP-002 through CIP-014) inside a bulk-electric-system operating environment.
• Strong technical writing and…
