## Description

Join our Advanced Processing Architectures organization as a Principal Embedded Platform Software Engineer, where you will influence the design, development, and integration of the foundational software that enables secure, deterministic, and high-performance operation of next-generation avionics processing platforms. In this role, you will define technical direction across programs, shape platform architecture, and guide teams developing critical early-boot, hardware-bring-up, HAL, diagnostic, and platform-security components that support advanced SoC and ASIC-based systems.

You will collaborate across systems, hardware, software, and verification disciplines to ensure cohesive platform behavior, introduce innovative solutions to complex hardware/software challenges, and drive engineering excellence through technical mentorship and cross-team leadership. This role provides an opportunity to influence program-level strategy, strengthen development workflows, and elevate the technical capabilities of the broader platform engineering community.

WHAT YOU WILL DO

 * Lead program-level technical strategy for embedded platform software, including secure boot flows, early-boot initialization, SoC/ASIC bring-up, HAL frameworks, diagnostics, and platform security features
 * Apply expert knowledge to design software for complex embedded multiprocessor systems and provide innovative solutions to challenging technical problems
 * Guide system architecture and review software designs for technical soundness, maintainability, and alignment with program goals
 * Define and improve development processes, workflows, and documentation practices across the program
 * Oversee integration and technical evaluation of supplier-provided bootloaders, BSP components, and platform software deliverables
 * Produce high-quality documentation including design artifacts, test procedures, integration guides, and internal training material
 * Collaborate closely with systems, hardware, safety, and software teams to ensure well-understood, repeatable, and reliable platform behavior
 * Utilize Agile development methods, automation tools, and continuous integration pipelines to drive efficient and consistent software delivery
 * Mentor engineers across levels (P1-P3) and support the development of future technical leaders
