The Software org is made up of several Centers located across the country, responsible for all aspects of the software development lifecycle. Our 4000+ software engineers design, develop, and build innovative solutions for our customers. Join our fast-paced agile teams on the leading edge of technology.

• Lead and oversee development of Linux kernel modules, device drivers, board-support packages, and low-level platform services for x86_64 and ARM embedded compute platforms, ensuring strong technical direction and consistent engineering quality.
• Provide technical leadership and architectural guidance for hardware interface implementations including PCIe (MMIO, MSI-X, DMA), UART, SPI/BPI, and other mission-critical I/O subsystems.
• Coordinate driver interface definitions and data contracts with Systems, FPGA, Sensor, and Hardware teams, ensuring alignment across hardware/software integration points and cross-domain dependencies.
• Guide driver integration activities across heterogeneous processing environments (CPU, GPU, accelerators), shaping how low-level components participate in larger compute pipelines.
• Lead design, maintenance, and review of platform boot and configuration artifacts such as DeviceTree, GRUB, U-Boot, and real-time kernel configurations (e.g., RedHawk).
• Direct debugging efforts for complex kernel-level or hardware-interaction issues in multi-node or distributed embedded environments, ensuring rapid resolution paths and robust root-cause analysis.
• Drive team execution within Agile processes, setting sprint priorities, guiding technical decompositions, and ensuring high-quality integration through CI/CD and DevSecOps pipelines (automated builds, testing, secure workflows).
• Lead performance optimization initiatives targeting low-latency and high-throughput driver workloads, ensuring drivers meet mission-critical throughput and real-time performance expectations.
• Champion secure coding and platform security practices, including SELinux/AppArmor, secure configuration hardening, and continuous improvements to driver quality, tooling, and development rigor.

• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 5 years of prior relevant experience.
• Experience in at least one systems-level programming language (e.g., C, C++, or Rust) and developing software in Linux environments.
• Experience with real-time, platform, or low-level system development concepts.
• Experience with CI/CD pipelines and/or DevSecOps practices and working within Agile software development methodologies (Scrum, Kanban, or similar).
• The ability to obtain and maintain a U.S. government issued security clearance is required.
• U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.

• Demonstrated leadership experience, formal or informal, such as mentoring junior engineers, coordinating small technical initiatives, facilitating team collaboration, driving engineering best practices, and/or guiding peers toward successful delivery.
• Familiarity with PCIe, MMIO, DMA, MSI-X, UART, SPI/BPI, and other hardware I/O standards.
• Familiarity with CMake, Conan, and/or Artifactory.
• Experience developing kernel modules, KO files, memory mapping, interrupts, and driver bring-up.
• Experience with Yocto, PetaLinux, DeviceTree, GRUB, U-Boot, or BSP tools.
• Exposure to IPMI, BIT, sensor system drivers, or other hardware integration workflows.
• Understanding of Linux OS security, SELinux/AppArmor, container security best practices.
• Experience with Ethernet, IP/TCP/UDP, or network interface development.
• Experience with VPX/SOSA architectures and embedded compute hardware.
• Knowledge of NVIDIA GPU drivers or CUDA for driver integration in compute pipelines.
• Active and transferable U.S. government issued Secret security clearance.

• Opportunity to lead development of mission-critical embedded software supporting national defense.
• Collaborative engineering environment with strong technical mentorship.
• Onsite team environment with hands‑on access to hardware and labs.
• Career development through Raytheon engineering advancement programs.

• Safety
• Trust
• Respect
• Accountability
• Collaboration
• Innovation
