Senior Systems Engineer

We don’t just build technology—we engineer the future. From next-gen aerospace to cutting-edge defense systems, we tackle the toughest, mission-critical challenges that keep people safe and push the limits of innovation. This is where problem-solvers, innovators, and big thinkers thrive. Quest Defense Systems & Solutions is seeking a Senior Systems Engineer to support the development of next-generation avionics computing technology for Collins Aerospace. This role will focus on a System-on-Chip (SoC) platform and requires strong experience working at the intersection of hardware and software. You will collaborate across systems, hardware, software, and AEH teams to capture requirements, support hardware/software integration, and verify system functionality in the lab. The ideal candidate will bring strong board- and device-level systems engineering experience, along with knowledge of ARP4754B, DO-254, and DO-178C. This position is primarily onsite in Cedar Rapids, IA, with limited remote consideration for rockstar candidates. Relocation assistance may be provided. U.S. Citizenship is required. Key Responsibilities: Capture, develop, and maintain system requirements, designs, test cases, and test procedures in accordance with program development plans and ARP4754B objectives. Support board- and device-level systems engineering for System-on-Chip (SoC) and embedded avionics applications. Work closely with systems, hardware, software, and Airborne Electronic Hardware (AEH) teams to support technical integration. Define and validate high-level hardware and software-allocated requirements. Integrate, validate, and verify embedded hardware and software functionality in a laboratory environment. Troubleshoot and resolve technical issues that cross hardware and software functional domains. Support development activities in accordance with DO-254 and DO-178C processes and certification objectives. Create and maintain technical documentation, requirements traceability, and development artifacts using tools such as Jama, Jira, and Git. Collaborate with technical stakeholders to develop use cases, concepts of operation, and system-level solutions. Support development of automation and scripting solutions for engineering, integration, or verification activities as needed. Participate in technical reviews and communicate findings, risks, and recommendations across engineering teams. Required Qualifications: Bachelor’s degree in Engineering, Computer Science, or another STEM discipline with 8+ years of relevant experience, or an advanced degree with 5+ years of relevant experience. Strong Systems Engineering experience at the board, device, or embedded hardware/software level. Experience supporting hardware/software integration for complex embedded or avionics systems. Experience developing, capturing, validating, and maintaining system and high-level requirements, including software- and/or hardware-allocated requirements. Working knowledge of safety-critical aerospace development standards, including ARP4754A/B, DO-254, and/or DO-178C. Experience with system integration, verification, validation, and troubleshooting in a laboratory environment. Ability to collaborate effectively across systems, hardware, software, and AEH/FPGA engineering disciplines. Strong technical documentation and communication skills. U.S. Citizenship required. Preferred / Differentiating Skills: Previous experience working on Collins Aerospace programs, including familiarity with Collins engineering processes, requirements capture, and documentation practices. Experience with System-on-Chip (SoC), processor-based, or other complex embedded computing platforms. Strong understanding of DO-254, DO-178C, and ARP4754A/B development and certification processes. Experience with avionics equipment certification and associated lifecycle documentation. Hands-on experience working with and testing embedded hardware and software at the board or device level.
