Collins Aerospace is a leader in technologically advanced, intelligent solutions that help redefine the aerospace and defense industry. Join us and help shape the future of aerospace and defense.

Collins Aerospace is looking for a Senior Systems Engineer to support the development and sustainment of communication products. The engineer will demonstrate a high level of professional competence and knowledge of the principles and techniques commonly used in systems development, integration, verification, and qualification related to avionics. The selected candidate will perform assignments requiring the use and application of systems engineering principles and techniques for the integration of hardware and software.

This role will require hands‑on software integration testing on target hardware, troubleshooting across hardware/software interfaces, and supporting both development and fielded product sustainment. This engineer must also have strong design, analytical, and problem‑solving skills for both hardware and software.

• Develop product-level requirements from customer and industry specifications. Further decompose requirements to support both software and hardware development.
• Perform trade studies to support and optimize the technical solution and requirements.
• Define integration and verification strategies for avionic functions and products, create test plans, test cases and procedures, execute system verification, and create test reports.
• Perform hands‑on integration of software applications, embedded software, system software, and hardware in a laboratory environment.
• Execute software integration testing on engineering development units, flight‑like hardware, production hardware, and/or hardware‑in‑the‑loop test benches.
• Troubleshoot and debug integration issues across hardware, software, firmware, operating systems, drivers, and external interfaces.
• Use lab equipment and engineering tools to support integration, verification, failure investigation, and root‑cause analysis.
• Analyze data gathered and develop solutions or alternative methods of proceeding to optimize performance and increase efficiencies in development activities.
• Communicate effectively to a host of stakeholders across the technical spectrum, including customers, program management, senior leadership, and functional teams.
• Provide technical support for fielded avionics systems through troubleshooting, root‑cause analysis, engineering changes, and lifecycle sustainment activities.

• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 5 years prior relevant experience or an Advanced Degree in a related field and minimum 3 years of experience.
• Experience with system‑level requirements decomposition and analysis, system design and allocation to subsystems/products, system integration planning and execution, and system‑level verification and validation.
• Experience integrating software applications, embedded software, or system software onto target hardware platforms.
• Experience developing, executing, and troubleshooting system integration test procedures in a lab or hardware‑in‑the‑loop environment.
• Experience debugging integration issues across hardware, software, firmware, operating systems, drivers, and external interfaces.
• Experience supporting root‑cause analysis, failure investigation, defect resolution, and verification closure for complex electronic systems.
• Ability to read and interpret system architecture diagrams, electrical schematics, interface control documents, software requirements, and test documentation.
• Experience documenting technical findings, test results, problem reports, and engineering recommendations in a clear and concise manner.
• Strong analytical and problem‑solving skills with the ability to isolate issues in complex hardware/software systems.

• Working knowledge of common communication interfaces and…
