Systems Engineer

Leidos Security Enterprise Solutions (SES) is seeking a Systems Engineer in the Aviation organization. This is a great opportunity for an experienced engineer to engage in hands-on work while developing a deep understanding of aviation security products. The role is highly impactful because the products being developed make travel and trade safer, healthier, and more efficient on a global level.

Working in a diverse and collaborative R&D environment, this position is responsible for providing system-level engineering support to maintain and enhance advanced X-ray scanners in the security industry . In this role, you will bridge the gap between initial concept and production, driving the integration and evaluation of complex electrical, mechanical, electro-mechanical, and software components. You will analyze system-level performance and reliability, replicate field issues in the lab, and collaborate across engineering disciplines to optimize our products. If you are a collaborative problem-solver with a strong background in power distribution, troubleshooting, and hands-on hardware debugging, we want to hear from you.

Primary Responsibilities:

• Electrical Design Execution: Perform fundamental engineering duties in electrical design efforts, including the development, integration, testing, measuring, and analysis/simulation of various products.
• Production Design Refinement: Refine conceptual designs into complete production designs, incorporating appropriate connectors, cables, and wiring to meet strict design criteria.
• Cost Optimization: Design alternative engineering solutions to reduce Bill-of-Materials (BOM) costs.
• Subsystem Integration: Integrate and test electrical, mechanical, electro-mechanical, and software subsystems.
• Lifecycle Management: Identify, evaluate, and source suitable replacements for end-of-life (EOL) components.
• System Troubleshooting: Diagnose and resolve complex, system-level performance and reliability issues.
• Cross-Functional Collaboration: Partner with Manufacturing Engineers to resolve production line issues and work alongside Field Support Engineers to optimize system performance.
• Root Cause Analysis: Replicate reported field problems in a laboratory environment to determine root causes.
• Test Infrastructure: Create custom test fixtures and define procedures to evaluate system components.
• Engineering Documentation: Author comprehensive documentation for system modifications and officially submit Engineering Change Orders (ECOs).

Basic Qualifications:

• Education & Experience: Bachelor’s degree in Electrical Engineering (or a closely related field) with 2+ years of relevant experience , OR a Master’s degree with 1–2 years of experience . Equivalent professional experience will be considered in lieu of a degree.
• PC Hardware Literacy: Proficient understanding of PC architecture and hardware computing components, including CPU, RAM, GPUs, hard drives, and internal power supply.
• Process Discipline: Strong documentation skills, rigorous process discipline, and acute attention to detail.
• Communication: Excellent written, verbal, and presentation communication skills.
• Core Design Background: Proven background in designing power distribution systems, electrical circuits, and cabling.
• Technical Fundamentals: Solid foundational knowledge of both analog and digital design.
• Schematic Literacy: Advanced technical expertise in reading, interpreting, and analyzing technical drawings and engineering schematics.

Preferred Qualifications:

• Prototyping: Hands-on experience with rapid prototyping and hardware debugging.
• Automation & Control: Development experience with Programmable Logic Controllers (PLCs).
• OS Competency: Proficiency working within Linux operating system environments; Windows experience is a plus.
• Programmable Logic : Familiarity with reading and programming FPGAs from a computer interface or host file.
