Raytheon is seeking a mid-level Senior Software Engineer - Device Driver Technical Lead to guide development of embedded Linux device drivers, kernel modules, and hardware/software integration supporting the RAIVEN Compute domain. This role provides hands-on technical leadership across low-level system components, ensuring high-performance, secure, and reliable driver functionality on VPX/SOSA-based compute platforms.

Requirements

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.

Nice To Haves

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.

Responsibilities

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.
