**Description**

SAIC is seeking a mid- to senior-level **Systems Engineer** to support the eXtensible Flight System (XFS), a configurable, modular software product used to develop advanced flight displays. In this role, you will lead and support systems engineering activities across the lifecycle of safety-critical avionics software developed under DO-178C (DAL C) objectives.

You will work closely with software, test, and human-factors/UX engineers to translate operational and certification requirements into well-structured system and software requirements, architectures, interfaces, and verification strategies. This position is ideal for an engineer who thrives on rigorous requirements engineering, system architecture, and disciplined verification in a standards-driven aerospace environment. This role will be onsite in **Huntsville, AL.**

**Responsibilities and Duties**

**Requirements Development & Management**

+ Elicit, analyze, and document system-level and software-level requirements for XFS-based flight display capabilities.

+ Ensure requirements are clear, consistent, testable, and traceable to customer needs, standards, and DO-178C DAL C objectives.

+ Decompose and allocate system requirements to software components and interfaces, maintaining end-to-end traceability from high-level requirements through design and test.

+ Manage requirements baselines and changes, performing impact analyses on architecture, design, integration, and verification activities.

+ Maintain requirements traceability matrices and support audits and reviews focused on requirements completeness and consistency.

**System Architecture & Design**

+ Develop and refine system and software architectures for XFS configurations, including modular display components, data interfaces, and integration with avionics systems.

+ Define and maintain interface control documents (ICDs) and data models for integration with sensors, flight management systems, and other avionics subsystems.

+ Collaborate with software engineers to ensure the architecture and requirements support performance, safety, configurability, and maintainability goals.

+ Analyze system behavior and performance, including resource usage, timing, and reliability in embedded/real-time environments.

**Safety-Critical & Standards-Driven Engineering**

+ Apply DO-178C and related aerospace standards and guidance to systems engineering and requirements activities.

+ Support the development of plans, standards, and guidelines (e.g., requirements standards, architecture guidelines) for XFS-based solutions.

+ Participate in safety, hazard, and risk analyses; derive safety-related requirements and constraints and ensure they are properly captured and traced.

+ Contribute to compliance evidence by producing and reviewing systems engineering and requirements artifacts required for audits and certification reviews.

**Verification, Validation & Test Support**

+ Define and maintain verification and validation strategies, including mapping of system and software requirements to test plans and procedures.

+ Develop and review test plans, procedures, and cases, ensuring they provide adequate coverage of requirements and key operational scenarios.

+ Support integration and system test activities, including anomaly investigation, root cause analysis, and requirements-focused corrective actions.

+ Work closely with test engineers to evaluate test results, confirm requirement satisfaction, and improve test effectiveness and traceability.

**Agile Collaboration & Technical Leadership**

+ Participate in agile ceremonies (backlog refinement, sprint planning, daily standups, reviews, retrospectives) representing systems and requirements engineering concerns.

+ Collaborate with software engineers, human-factors/UX specialists, and customer stakeholders to refine features and ensure they meet operational needs and certification constraints.

+ Lead or contribute to technical reviews (requirements reviews, architecture/design reviews, test readiness reviews) to ensure quality and compliance.

+ Provide mentorship and guidance to junior systems engineers and cross-functional team members on requirements and systems engineering best practices.

**Documentation, Configuration Management & Continuous Improvement**

+ Develop and maintain systems engineering documentation, including requirements specifications, architecture descriptions, ICDs, and verification reports.

+ Ensure systems engineering and requirements artifacts are properly baselined, controlled, and integrated with configuration management tools and processes.

+ Identify opportunities to improve requirements management, architecture practices, and verification workflows, and help implement process and tool enhancements.

+ Support customer interactions and technical presentations, clearly communicating requirements rationale, system capabilities, constraints, and trade-offs.

**Qualifications**

**Education Requirements**

+ Bachelor’s degree in Systems Engineering, Electrical/Computer Engineering, Aerospace Engineering, or related technical field and five (5) years’ experience; Additional six (6) years’ experience can be considered in lieu of degree.

**Clearance Requirements**

+ Must hold, or be eligible to obtain and hold, security clearance of Secret or higher; US Citizenship required.

**Required Skills and Qualifications**

+ Typically 5–10+ years of experience in systems engineering or closely related roles, preferably on complex software-intensive or avionics systems.

+ Strong experience in requirements engineering: elicitation, analysis, decomposition, allocation, baselining, and traceability.

+ Experience developing system and software architectures, defining interfaces, and working with multidisciplinary teams to realize designs.

+ Familiarity with DO-178B/C concepts and the role of systems engineering and requirements management in safety-critical software development and certification.

+ Experience collaborating closely with software engineering teams; ability to understand and discuss software design and implementation trade-offs in the context of requirements.

+ Strong analytical and problem-solving skills, including the ability to perform impact analyses and resolve complex integration and requirement issues.

+ Proficiency with requirements management practices and tools (e.g., traceability matrices, baseline control, change management).

+ Clear written and verbal communication skills, with experience producing technical documentation and participating in formal reviews.

**Preferred**

+ Experience in aerospace, avionics, or other safety-critical domains (e.g., flight displays, flight management systems, or navigation/mission systems).

+ Direct experience supporting DO-178C DAL C or higher programs, including certification evidence preparation and audit support.

+ Hands-on experience with requirements management tools, preferably IBM Engineering Requirements Management DOORS (DOORS Classic or DOORS Next Generation).

+ Experience with configuration management and issue tracking tools (e.g., Git-based repositories, Jira).

+ Experience with Microsoft Azure DevOps for work item tracking, requirements organization, and coordination with development and test pipelines.

+ Familiarity with scripting or basic programming (e.g., Python, C) to support data analysis, requirements verification, or tool integration.

+ Prior experience mentoring engineers or acting as a technical lead for systems and requirements engineering activities.
