Essential Functions:

• Work with the ATLAS Chief Systems Engineer to lead assigned systems engineering activities across the ATLAS program and support related enterprise and system-of-systems initiatives.
• Collaborate with government, customer, and enterprise stakeholders to capture mission needs, requirements, and use cases; maintain traceability through ATLAS design, implementation, integration, and verification.
• Assess how ATLAS requirements, interfaces, and design changes affect related systems and end-to-end mission capabilities.
• Coordinate with engineering teams across related programs to define and manage external interfaces, integration dependencies, and interoperability requirements.
• Support alignment of ATLAS architecture and technical baselines with applicable enterprise architectures, standards, and capability roadmaps.
• Lead or support system and system-of-systems integration and test activities, including assessments of functionality, timing, interfaces, and end-to-end mission performance.
• Identify and manage program-level and cross-program technical risks and dependencies; elevate issues requiring Chief Systems Engineer, program leadership, or enterprise stakeholder decisions.
• Participate in program and enterprise technical forums to communicate status, resolve cross-system issues, and support coordinated technical planning.

Qualifications:

• Bachelor’s Degree and minimum 9 years of prior relevant experience. Graduate Degree and a minimum of 7 years of prior related experience. In lieu of a degree, minimum of 13 years of prior related experience.
• Experience applying systems engineering principles throughout the development lifecycle, including requirements analysis, architecture development, integration, and verification.
• Experience working in an Agile development environment and translating system requirements into actionable development priorities.
• Experience coordinating technical activities across multiple systems, programs, or organizations, including interface management and integration planning.
• Active DoD Secret security clearance and willingness and eligibility to obtain a Top Secret clearance with Sensitive Compartmented Information (TS/SCI) access.

Preferred Additional Skills:

• Ability to lead complex technical efforts, resolve cross-functional issues, and manage competing priorities with limited oversight.
• Working knowledge of Atlassian tools, including Jira and Confluence, and experience supporting backlog management.
• Familiarity with microservices architecture concepts and distributed system interfaces.
• Experience supporting enterprise architecture, system-of-systems engineering, or cross-program capability planning.
• Experience planning and executing systems integration and test (SIT) activities, including test procedures, results analysis, and discrepancy resolution.
• Familiarity with Python scripting for data analysis, test automation, or engineering workflow improvement.
• Experience developing system observability capabilities, including metrics, dashboards, logging, and health monitoring.
• Experience conducting architecture trade studies and evaluating technical, cost, schedule, and operational impacts.
• Familiarity with model-based systems engineering (MBSE) tools and practices.
• Experience mentoring engineers and leading technical reviews.
• Familiarity with multinational information-sharing and releasability considerations, including Five Eyes (FVEY) environments.
