About Peraton

Peraton is a next-generation national security company that drives missions of consequence spanning the globe and extending to the farthest reaches of the galaxy. As the world’s leading mission capability integrator and transformative enterprise IT provider, we deliver trusted, highly differentiated solutions and technologies to protect our nation and allies. Peraton operates at the critical nexus between traditional and nontraditional threats across all domains: land, sea, space, air, and cyberspace. The company serves as a valued partner to essential government agencies and supports every branch of the U.S. armed forces. Each day, our employees solve the most daunting challenges that our customers face. Visit peraton.com to learn how we’re keeping people around the world safe and secure.

About The Role

Peraton is seeking an experienced Enterprise Cybersecurity Architect to define and lead the cybersecurity architecture strategy across the BNATCS program where cybersecurity is inseparable from safety. In this environment, a security failure is not merely a data breach — it can directly endanger human life, disrupt the national airspace, and compromise public safety. This role demands an architect who understands that every security design decision carries safety implications and who can embed that mindset across the entire integrated enterprise.

In Peraton's role as a systems integrator, you will be responsible for securing the full spectrum of integrated systems — custom-developed, COTS, GOTS, and third-party vendor components — ensuring that cybersecurity controls are consistent, enforceable, and verifiable across organizational and technical boundaries. You will serve as the principal authority on enterprise cybersecurity architecture, guiding engineering teams, subcontractors, and program leadership through the unique challenge of protecting safety-critical systems in an evolving threat landscape.

This role is based in Herndon, VA.

Responsibilities:

Security Architecture & Strategy

Define and maintain the enterprise cybersecurity architecture vision, encompassing network security, application security, data protection, identity and access management, and endpoint security across all integrated systems

Develop and govern cybersecurity reference architectures, standards, and design patterns that ensure consistent security posture across internal teams, subcontractors, and vendor-delivered components

Drive the enterprise-wide adoption of Zero Trust Architecture (ZTA), defining segmentation strategies, identity verification models, and least-privilege access controls appropriate for safety-critical environments

Lead cybersecurity technology roadmap development, identifying strategic investments, capability gaps, and modernization priorities across the security portfolio

Safety-Critical Cybersecurity

Architect cybersecurity controls that account for the safety-of-life implications inherent in aviation systems — ensuring that security mechanisms do not introduce latency, single points of failure, or operational disruptions that could compromise airspace safety

Integrate cybersecurity requirements with safety engineering and system assurance processes, ensuring that security risk assessments are conducted alongside safety hazard analyses

Design resilience and continuity architectures — failover, graceful degradation, and recovery strategies — that maintain both security and safety posture during cyber incidents

Develop security architectures for real-time, low-latency, and high-availability systems where traditional security controls must be adapted to meet stringent operational performance requirements

Integration Security & Governance

Conduct security architecture assessments across the integrated system portfolio, identifying vulnerabilities, trust boundary gaps, and inconsistencies in security controls between vendor and custom components

Define and manage security interface requirements and security-relevant interface control documents (ICDs) for all system-to-system data exchanges across the integrated enterprise

Conduct technical security reviews of vendor and subcontractor deliverables to ensure alignment with enterprise cybersecurity standards, secure coding practices, and compliance requirements

Establish and chair security architecture review boards to evaluate proposed designs, adjudicate security trade-offs, and enforce architectural standards across all integrated systems

Compliance & Risk

Ensure enterprise-wide compliance with FedRAMP, RMF, NIST 800-53, FISMA, FAA cybersecurity directives, and agency-specific security policies

Lead threat modeling, risk assessments, and attack surface analyses across the integrated enterprise, with particular attention to safety-critical system boundaries

Collaborate with cybersecurity operations, incident response, and security monitoring teams to ensure that architectural designs support effective detection, response, and recovery capabilities

Architect security solutions for hybrid and multi-cloud environments (AWS GovCloud, Azure Government) that meet federal compliance requirements while supporting mission performance

Leadership & Communication

Translate complex cybersecurity risks, architectural trade-offs, and safety-security interdependencies into clear, actionable guidance for executive stakeholders, program managers, and government customers

Mentor and guide security engineers, solution architects, and development teams to ensure cybersecurity and safety intent is preserved from design through implementation and integration

Drive cross-functional alignment across cybersecurity, software engineering, data architecture, infrastructure, and operations teams

US Citizenship
Public Trust Clearance - Ability to Obtain and Maintain

Demonstrated experience serving as a cybersecurity architect within a systems integrator environment, securing multi-vendor, multi-technology solutions across complex trust boundaries

Deep expertise in Zero Trust Architecture, network security design, identity and access management (IAM), and data protection strategies at enterprise scale

Proven experience securing safety-critical or mission-critical systems where cybersecurity failures carry operational or life-safety consequences

Mastery of FedRAMP, RMF, NIST 800-53, FISMA, and federal cybersecurity governance frameworks

Hands-on experience with security technologies including SIEM, SOAR, EDR, CSPM, IAM platforms, PKI, and network segmentation tools

Strong understanding of cloud security architecture on AWS and/or Azure, including cloud-native security services, landing zone security, and workload protection

Experience conducting threat modeling, risk assessments, and security architecture reviews across heterogeneous integrated environments

Familiarity with safety engineering principles (e.g., system safety, hazard analysis, fault tolerance) and their intersection with cybersecurity

ITIL certification and experience integrating cybersecurity governance with ITSM processes

Proven ability to lead cross-functional teams and drive security alignment across engineering, operations, and subcontractor organizations

Preferred Qualifications

Experience securing FAA, aviation, or national airspace systems and familiarity with aviation-specific cybersecurity requirements and safety standards

Background in securing real-time systems, low-latency architectures, and edge computing environments where traditional security controls require adaptation

Experience with network security architecture (SD-WAN, secure transport, micro-segmentation) within large-scale integrated environments

Familiarity with AIOps, security observability platforms, automated threat detection, and security orchestration at enterprise scale

Experience with DevSecOps pipeline security — static/dynamic analysis, container security, software supply chain security, and secure CI/CD practices

Hands-on experience with model-based systems engineering (MBSE) or architecture modeling tools for security architecture documentation

Relevant certifications such as CISSP, CCSP, CISM, or GICSP (Global Industrial Cyber Security Professional)

Experience with EO 14028 (Improving the Nation's Cybersecurity) compliance

OMB M-22-09 Zero Trust implementation experience
