Leidos is seeking a Senior Systems Architect to support an upcoming program in Chantilly, VA. The successful candidate will join a talented team at the forefront of enterprise ServiceNow capabilities, ServiceNow integrations, Signals Intelligence (SIGINT), and Cryptographic Key Management.

This role will serve as a senior technical leader responsible for the integration, engineering, sustainment, and operational support of enterprise ServiceNow capabilities supporting Broadside within the OHR environment.

The ideal candidate brings a strong systems engineering background, demonstrated experience integrating enterprise platforms and services, and the ability to coordinate complex technical activities across government, industry, and mission partner organizations.

The Senior Systems Architect will work across multiple technical domains to ensure system interoperability, resolve integration challenges, manage technical dependencies, and maintain secure, reliable, and mission-ready capabilities.

This individual will also contribute to modernization initiatives, technical risk management, configuration control, and Risk Management Framework (RMF) compliance while ensuring solutions align with established enterprise architecture standards and mission requirements.

This is an opportunity for a technically accomplished professional who thrives in a collaborative environment, can translate complex technical requirements into actionable engineering solutions, and is comfortable providing technical direction across organizational boundaries. Primary Responsibilities.

Systems Architecture and Technical Leadership: Serve as the senior technical lead for the integration, sustainment, and operational support of enterprise ServiceNow capabilities supporting Broadside. Provide technical guidance on architecture, integration strategies, system dependencies, and implementation approaches to ensure solutions meet operational and mission requirements.

ServiceNow Integration and Interoperability: Lead and support the design, implementation, troubleshooting, and sustainment of ServiceNow integrations with enterprise systems, applications, services, and supporting infrastructure. Evaluate integration requirements, identify interface dependencies, and help ensure reliable information exchange across interconnected systems.

Cross-Organizational Coordination: Collaborate with government stakeholders, Federally Funded Research and Development Centers (FFRDCs), Systems Engineering and Technical Assistance (SETA) contractors, platform providers, cybersecurity teams, and other service providers.

Coordinate technical dependencies, facilitate issue resolution, and align engineering activities across organizations to support successful delivery of mission capabilities. Systems Engineering and Interface Management: Lead systems engineering activities related to ServiceNow integration, infrastructure support, interface management, configuration control, and technical documentation within the OHR environment.

Support the development and maintenance of system architecture artifacts, interface specifications, technical baselines, and engineering documentation as required. Operational Sustainment and Service Reliability: Support the day-to-day health, availability, and performance of enterprise capabilities.

Analyze operational issues, coordinate troubleshooting and root-cause analysis, recommend corrective actions, and help ensure continuity of service for mission-critical systems.

Cybersecurity and RMF Compliance: Coordinate with cybersecurity and system authorization stakeholders to support Risk Management Framework (RMF) requirements, security control implementation, compliance documentation, vulnerability remediation, and ongoing authorization activities. Ensure engineering solutions account for applicable security requirements and established government policies.

Technical Risk Management: Identify, assess, and communicate technical risks, integration challenges, infrastructure constraints, and potential impacts to operational capabilities. Develop mitigation strategies, recommend engineering solutions, and coordinate corrective actions to minimize mission disruption.

Configuration Management and Change Control: Support configuration control, technical baseline management, change evaluation, and implementation planning. Assess proposed changes for potential impacts to interfaces, dependent systems, security posture, and operational performance.

Modernization and Continuous Improvement: Provide technical leadership for modernization initiatives, platform enhancements, integration improvements, and operational process optimization. Identify opportunities to improve system reliability, simplify workflows, reduce manual effort, and increase the effectiveness of enterprise service delivery.

Technical Documentation and Knowledge Management: Develop, review, and maintain architecture documentation, standard operating procedures, operations manuals, integration specifications, troubleshooting guides, and other technical artifacts. Ensure documentation is accurate, accessible, and useful to engineering teams, operators, and program leadership.

Testing and Quality Assurance: Support integration testing, functional validation, regression testing, and operational acceptance activities. Evaluate test results, document discrepancies, coordinate defect resolution, and provide technical recommendations to improve system quality and reliability.

Automation and Scripting: Leverage scripting and automation technologies to streamline operational tasks, support data processing, improve troubleshooting efficiency, and reduce repetitive manual activities. Apply scripting solutions where appropriate to enhance system administration and integration workflows.

Stakeholder Communication and Mission Support: Communicate complex technical issues, engineering recommendations, risks, and implementation plans to technical teams, government stakeholders, and program leadership. Foster effective collaboration and maintain alignment between technical execution and evolving mission priorities.
