About the role

Familiarity with AC 20-193 guidance for multicore processor certification and/or TSO-C153a is highly desired.
This is where problem-solvers, innovators, and visionary thinkers come together to shape the future.

Design, develop, integrate, and support platform software for safety-critical embedded avionics systems operating in multicore environments.
Perform or support Worst-Case Execution Time (WCET) analysis with consideration for interference from GPUs, I/O subsystems, SSDs, FPGAs, and other shared resources.
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.
Develop technical documentation and engineering artifacts supporting platform design, performance analysis, and certification objectives.

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.
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.

Practical experience with DEOS RTOS.
Experience with cache partitioning, resource isolation, and resource management in multicore RTOS environments.
Experience supporting multicore certification planning, analysis, or compliance activities.
Experience supporting avionics display systems, flight deck systems, mission computers, or other aerospace embedded platforms.
Experience working with GPU interaction, shared memory behavior, or graphics-related performance impacts within embedded systems.
