Job summary

Quest Defense Systems & Solutions is seeking a Senior Embedded Platform / Multicore Software Engineer to advance platform software for safety-critical avionics displays. You will work on multicore architectures, RTOS-based development, and performance analysis in a demanding aerospace environment.

The role requires DO-178B/C experience, DEOS or equivalent RTOS familiarity, and strong collaboration with software, systems, graphics, and hardware teams. Hybrid work in Phoenix with U.S.

Qualifications

• Bachelor’s degree in Computer Engineering, Computer Science, Electrical Engineering, or a related technical discipline.
• 10+ years of experience developing software for embedded, real-time, or safety-critical systems.
• Strong programming experience in C and/or C++ within embedded software environments.
• Experience with DEOS, partitioned real-time operating systems, or other safety-critical RTOS platforms such as VxWorks, Integrity, LynxOS, PikeOS, or similar.
• Experience working within DO-178B and/or DO-178C software development environments.
• Strong understanding of multicore processor architecture and system-level behavior.
• Experience with processor and memory architecture concepts, including shared memory access, cache hierarchy, memory controllers, and DDR/main memory systems.
• Experience analyzing embedded software performance, timing behavior, or resource utilization in multicore systems.
• Understanding of shared resource monitoring and analysis techniques, including performance counters, QoS, or related approaches.
• Experience performing or supporting WCET analysis, timing analysis, or deterministic performance evaluation.
• Ability to evaluate system interference impacts from shared resources such as GPU, I/O, FPGA, storage, memory, or other hardware resources.
• Strong written and verbal communication skills with the ability to collaborate across software, systems, hardware, graphics, and certification teams.
• Familiarity with FAA multicore certification guidance, including AC 20-193 and/or experience with TSO-C153a, Integrated Modular Avionics, or IMA platform/module certification considerations.
• U.S. Citizenship or U.S. Permanent Resident status.

Responsibilities

• Design, develop, integrate, and support platform software for safety-critical embedded avionics systems operating in multicore environments.
• Analyze multicore processor behavior, shared resource usage, and system-level performance across CPUs, GPUs, memory subsystems, I/O, FPGAs, storage devices, and other integrated hardware resources.
• Evaluate processor and memory architecture considerations, including cache hierarchy, memory controllers, DDR/main memory systems, and shared memory access across multiple cores.
• Perform or support WCET analysis with consideration for interference from GPUs, I/O subsystems, SSDs, FPGAs, and other shared resources.
• Utilize performance counters, QoS mechanisms, and other monitoring approaches to assess shared resource utilization and performance impacts.
• Develop and support deterministic execution strategies, including cache partitioning, resource isolation, and resource management within RTOS-based environments.
• Support DEOS or equivalent RTOS configuration, integration, troubleshooting, and performance optimization activities.
• Collaborate with software, systems, graphics, and hardware teams to identify and resolve platform-level performance issues and multicore interference concerns.
• Support software verification, validation, documentation, and certification activities in accordance with safety-critical aerospace development processes.
• Participate in architecture reviews, technical trade studies, multicore performance assessments, and certification planning discussions.
• Develop technical documentation and engineering artifacts supporting platform design, performance analysis, and certification objectives.
• Provide technical guidance to engineering teams on multicore platform behavior, RTOS performance, shared resource management, and deterministic execution.
