## Description

Leidos is seeking Senior 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.

Please note, this exciting position is currently unfunded and is in anticipation of future work.

As a member of a Scaled Agile software development organization, you will contribute to the technical execution of a program that integrates proven, globally deployed technologies with modern cloud-native capabilities. You will work alongside cross-functional teams and technical leaders to deliver predictable outcomes in a highly regulated, safety-critical environment.

In this position, you will serve as the dedicated Systems Engineer for an Agile/SAFe development team, partnering closely with Product Owners, architects, software engineers, testers, DevSecOps engineers, and customer stakeholders to define, refine, and validate system capabilities. You will ensure that operational needs, regulatory requirements, and system-level behaviors are fully understood, traceable, testable, and aligned to program objectives throughout the development lifecycle. This position supports government programs and requires the ability to obtain and maintain a favorable Public Trust investigation.

Primary Responsibilities

 * 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 DevSecOps 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.
