Avionics Systems Engineer

Shape the future of innovation as we tackle cutting-edge projects that make a difference. We're not just in the business of engineering—we're building a brighter future. Driven by creativity and a culture of excellence, we believe in the power of engineering to solve today's challenges and create opportunities for tomorrow. What we do matters. Quest Defense Systems & Solutions is seeking an experienced and detail-oriented Systems Engineer to support the full lifecycle development of complex aerospace and defense systems, with a focus on the Health Awareness System Subsystem for a next-generation aircraft program. This role centers on requirements authoring, decomposition, traceability, and verification readiness within a structured systems engineering environment aligned to the V-Model lifecycle. The selected candidate will work to develop clear, testable system and subsystem requirements and ensure they are properly linked to verification strategies through development and maintenance of the Requirements Verification Traceability Matrix (RVTM). This individual will play a key role on the front end of the V-model while also supporting downstream verification activities, test documentation, and overall system maturity as the program progresses. The role also supports Model-Based Systems Engineering (MBSE) activities and contributes to system architecture alignment, technical reviews, and lifecycle milestones. Experience supporting avionics, mission systems, health monitoring architectures, or other safety-critical aerospace platforms is highly desirable. Due to the nature of the project, all applicants must be U.S. citizens or US lawful permanent residents. This role is highly desired to be onsite in Fort Worth, TX, though remote candidates may be considered.

Key Responsibilities:
