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.

What You Will Do

• 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.

Qualifications You Must Have

• 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.​

Qualifications We Prefer

• 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.

What We Offer

• 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.

• Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world. At RTX we value: Safety, Trust, Respect, Accountability, Collaboration, and Innovation.
