Within the Defense Sector, the Airborne Systems Business Area at Leidos currently has an opening for a talented Senior Embedded Flight Software Architect to work in our Huntsville office. This is an exciting opportunity to use your knowledge, experience, and design expertise to envision, formulate and design the capabilities of embedded software for flight systems.

This position primarily focuses on the system and software design of robust, innovative, modular software for real-time embedded airborne systems. The position’s secondary focus is the design of software to support fielding, operations, support, and maintenance of embedded software products.

The position’s duties include architecture work on different software products across the system: embedded flight software, analysis tools/simulations, mission planning software, and components of mission-critical systems.

This position will touch a variety of embedded computing technologies, hardware, interfaces, and development/debugging tools, such as device drivers, flash memory, bootloaders, board support packages, printed circuit boards (PCBs), microcontrollers, JTAG interfaces, real-time operating systems (RTOS), single-board computers, systems-on-chip (SoCs), and varying levels of communications protocols.

The position will also encompass technical advisement to program teams, capture teams, customers/stakeholders, talent acquisition specialists, and senior leaders of Leidos business organizations. Evaluation of candidates for this position will have a technical emphasis with focus on architectural competency demonstrated through structured interviews, design exercises and discussions, and validity of concepts.

Candidates should be prepared to discuss their prior experience with system and software design, architectural decision-making, technical contributions and leadership, demonstrated versatility, increasing technical responsibility, and career growth. ## Primary Responsibilities - Design embedded software structures, interfaces, and behaviors for airborne systems that are modular, composable, open, testable, reusable, scalable, resilient to evolving requirements, and conformant to relevant standards. - Provide hands-on technical leadership throughout software development, including implementation in embedded programming languages such as C, C++, or Rust; guiding firmware development; supporting initial integration and testing on target embedded computing platforms; and directly contributing when appropriate. - Develop and evaluate conceptual flight software architectures for primary and supporting systems, considering new development, reuse of existing software assets, hybrid approaches, and the technical, cost, schedule, and risk tradeoffs among alternative solutions. - Identify relevant standards, practices, processes, and deliverables.

Guide software teams to develop in accordance with them and continually perform hands-on reviews and mentoring. - Collaborate closely with software developers, program teams, solution architects, and corporate technical leadership.

Maintain accountability for the technical integrity of assigned architectures and designs, proactively seeking independent reviews, challenging assumptions, and incorporating constructive technical feedback. - Collaborate with and advise Software IPT Leads, Technical Leads, and Test Leads on approaches for software project execution, estimation, development, verification, validation, and presentations to customers/stakeholders. - Collaborate closely with systems engineers to model and maintain software architectures using model-based systems engineering (MBSE) techniques, applicable modeling standards, frameworks, methodologies, and reference architectures. - Assist electrical designers with the formulation of solutions, trade studies, and selection of electrical systems and embedded computing hardware platforms. - Support working groups and consortia with software architecture expertise, requests for comments (RFCs), and contributions. - Assist software development teams by participating in Agile planning, writing epics and high-level stories, task estimation, execution, and progress reporting. - Participate in requirements and design reviews to maintain consistency and quality of the architecture and overall solution, to include regular sharing of relevant architectural knowledge with the team. - Contribute solutions, software architectures, and evidence-based estimates to proposals and advise capture teams with software subject-matter expertise. - Communicate directly and regularly with customers, end users, and other team members. - Other software architect-related technical duties as assigned.

This position requires a high degree of flexibility towards work assignments. ## Basic Qualifications - Candidate must possess at least a bachelor’s degree in Software Engineering, Computer Science, Computer Engineering, Electrical Engineering, Aerospace Engineering, Mathematics, or equivalent technical degree. - Candidate must be a U.S. citizen and be eligible to obtain and maintain a U.S.

Department of Defense security clearance at the Secret level. - Candidate should have 12 or more years of relevant technical experience. Relevant academic, internship, research, or professional technical experience may be considered.

Note: Advanced degrees and specifically relevant architecture training/certification may reduce the amount of experience required. - Prior relevant technical experience must include developing, integrating, testing, and/or troubleshooting embedded software or embedded-adjacent applications that interface with, operate, monitor, support, simulate, control, or communicate with embedded systems. - Candidate should have extensive knowledge of disciplined software engineering practices, such as requirements analysis, configuration management, version control, coding standards, peer review, unit and integration testing, automated testing frameworks, and software verification. - Candidate must demonstrate strong competency in formulating and expressing software architectures using one or more industry-recognized design techniques or notations, along with the ability to quickly learn and effectively apply unfamiliar design techniques. - Candidate must be able to evaluate software architectures against functional requirements, system-level quality attributes, performance constraints, integration risks, and lifecycle considerations, including documenting and communicating architectural decisions and their rationale. - Candidate must demonstrate competency with one or more architectural design patterns, one or more detailed design patterns, and object-oriented design principles. - Candidate must be familiar with one or more embedded processor architectures and their application in microcontrollers, systems-on-chip (SoCs), systems-on-modules (SoMs), or similar implementations. - Candidate must demonstrate substantial knowledge of design considerations for performance-constrained
