Systems Engineer

Overview

Lead Systems Engineer – Agile Team Systems Engineering. Leidos is seeking Lead Systems Engineers to join the Air Traffic Business Area within the Homeland Sector, supporting the development of next-generation flight service and air traffic systems. This work aligns with the FAA’s broader initiative to modernize legacy flight service capabilities, replacing aging infrastructure with scalable, cloud-based platforms designed to improve safety and operational efficiency—particularly in remote and high-dependency aviation environments.

These efforts focus on delivering mission-critical, future-ready solutions that provide safety-critical flight services to the pilot community.

• Review FAA requirement documents, advisory circulars, and applicable regulations (e.g., 14 CFR parts) to extract intent, constraints, interfaces, and acceptance criteria.
• Translate operational and regulatory requirements into detailed, testable system requirements, features, and acceptance criteria that support Agile development activities.
• Collaborate with Product Owners and development teams to refine backlog items, clarify system behaviors, and ensure technical completeness and traceability.
• Engage with customer stakeholders, operators, and subject matter experts to identify use cases with an emphasis on completeness, testability, alignment with operational workflows, and readiness for validation trials.
• Decompose high-level regulatory and operational requirements into specific capability statements with measurable performance criteria and traceability to FAA compliance outcomes.
• Develop and maintain requirements traceability between stakeholder needs, system requirements, architecture artifacts, implementation tasks, and verification activities.
• Support system design discussions by evaluating technical approaches, documenting trade-offs, identifying integration impacts, and assessing operational or regulatory risks.
• Prepare and review technical documentation, including system specifications, interface definitions, use cases, operational workflows, verification plans, and requirements traceability matrices.
• Participate in Agile ceremonies, technical interchange meetings, structured reviews, and system inspections.
• Coordinate with software engineering, test, cybersecurity, and Dev Sec Ops  teams to ensure system requirements are fully implemented, validated, and operationally supportable.
• Assist in defining verification and validation strategies, including support for demonstrations, integration testing, operational assessments, and customer reviews.
• Systematically capture and communicate design decisions, performance trade-offs, compliance rationales, and risk assessments to support program transparency and technical governance.

• Bachelor’s degree in computer science, engineering, systems engineering, or a related field with 4–8 years of relevant experience, or a Master’s degree with 2–6 years of experience
• Experience working within Agile development environments, including familiarity with Agile methodologies, principles, and tools
• Experience performing systems engineering activities across the system development lifecycle, including requirements analysis, decomposition, traceability, integration, and verification
• Strong understanding of disciplined engineering processes and attention to detail in highly regulated or mission-critical environments
• Experience collaborating with cross-functional technical teams, customers, and stakeholders to define and refine system capabilities
• Experience preparing and maintaining technical documentation and requirements artifacts
• Familiarity with software development concepts, architectures, interfaces, and integration considerations
• Clear and effective verbal and written communication skills
• Experience with cloud-based systems and modern software architectures
• Ability to obtain SF-85 Public Trust suitability determination
• US Citizenship

• Experience with Java, Python, React, and scripting languages
• Knowledge of AI-assisted development workflows and tools (i.e., Claude Code, Codex, etc.)
• Knowledge of Dev Sec Ops  practices and CI/CD…
