Join the elite team at QDSS, where our engineers are at the forefront of developing cutting-edge Aerospace, Defense, Space, and Medical Device products. Your work will make a real impact, contributing to the core of engineering solutions that drive technological advancements.  Quest Defense Systems & Solutions is seeking a highly experienced Aircraft Systems Safety Engineer to support the aircraft-level safety assessment and certification of an advanced integrated avionics and cockpit platform. This role will evaluate how flight controls, flight management, displays, navigation, guidance, and network communications interact within the overall aircraft architecture. The ideal candidate will have 10+ years of aircraft systems safety, airworthiness, or avionics certification experience, with strong hands-on knowledge of SAE ARP4761 and ARP4754A. Responsibilities include developing aircraft and system-level FHAs, Preliminary System Safety Assessments, Fault Tree Analyses, FMEAs, Common Mode Analyses, and FDAL/IDAL determinations. This is a commercial aircraft program, so direct ARP4761 experience is essential. Experience with CAFTA or RELEX and requirements traceability using DOORS is highly valued. Hybrid work in Phoenix, AZ is preferred; however, qualified remote candidates will be considered. U.S. Citizenship or U.S. Permanent Resident status is required. Key Responsibilities:     Develop and maintain aircraft- and system-level safety assessments for an integrated avionics and cockpit architecture. Perform Functional Hazard Assessments, Preliminary System Safety Assessments, Fault Tree Analyses, FMEAs, and Common Mode Analyses in accordance with SAE ARP4761 and ARP4754A. Create system-level fault trees using CAFTA, RELEX, or a comparable fault tree analysis tool. Work with flight controls, flight management, displays, navigation, guidance, communications, and other engineering teams to evaluate system interactions and hazard effects. Translate aircraft-level safety objectives into architectural decisions, system requirements, and hardware and software allocations. Perform FHA, FDAL, and IDAL analyses and maintain traceability between hazards, safety requirements, design decisions, and verification evidence. Review system, subsystem, hardware, and software designs to confirm that safety requirements and mitigations are properly implemented. Review OEM safety assessments, technical requirements, product-level analyses, and certification documentation for completeness and compliance. Support system design reviews, safety reviews, flight-test activities, customer meetings, and discussions with certification authorities. Provide aircraft systems safety expertise throughout the development, integration, verification, and certification lifecycle. Required Qualifications:   10+ years of experience in aircraft systems safety, airworthiness, avionics systems engineering, or a closely related field. Hands-on experience performing commercial aircraft safety assessments in accordance with SAE ARP4761 and ARP4754A. Experience developing and maintaining aircraft- or system-level FHAs, Preliminary System Safety Assessments, Fault Tree Analyses, FMEAs, and Common Mode Analyses. Strong understanding of integrated avionics and real-time airborne systems, including the interaction of cockpit functions such as flight controls, flight management, displays, navigation, guidance, and communications. Experience translating aircraft-level hazards and safety objectives into system requirements, architectural decisions, and hardware and software allocations. Experience creating or reviewing system-level fault trees using CAFTA, RELEX, or a comparable fault tree analysis tool. Experience managing safety requirements, allocations, and traceability using DOORS, DOORS Next Generation, or a comparable requirements management tool. Ability to review complex system a
