We deliver solutions that help our nation and allies defend freedoms and deter aggression, creating a safer, more secure world. Join us and help shape the future of aerospace and defense.

Raytheon is seeking a mid‑level Embedded Software Engineer to join our engineering team supporting development of advanced defense, sensing, and EO/IR systems. This role focuses on Linux‑based compute platforms, data‑processing frameworks, and hardware/software integration on VPX/SOSA architectures. The ideal candidate has experience building scalable, secure, and mission‑critical software services running on x86_64 and ARM‑based single board computers.

What You Will Do

• Develop software components that provide core compute‑platform services, including data transport, scheduling, and processing orchestration
• Implement and maintain frameworks enabling scalable, high‑throughput, and low‑latency processing pipelines
• Define platform interfaces, APIs, and data contracts in coordination with Systems, FPGA, Sensor, and Hardware teams
• Integrate software across Linux‑based compute nodes and heterogeneous processing environments (CPU/GPU/accelerators)
• Manage and configure Linux OS environments and containerized runtime systems (Docker/Podman) to support platform deployment and operation
• Participate in Agile development, ensuring high‑quality code integration through CI/CD and DevSecOps pipelines
• Conduct performance profiling and optimization for compute workloads and platform services
• Diagnose and resolve complex issues in distributed, multi‑process, or multi‑node compute environments
• Contribute to improvements in platform architecture, development tooling, and overall software quality practices

Qualifications You Must Have

• Typically requires a degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 5 years of prior relevant engineering experience.
• Experience in at least one systems‑level programming language (e.g., C, C++, or Rust) and developing software on Linux systems.
• Real time or low‑level system development experience.
• Experience applying Agile software development methodologies (Scrum, Kanban, or similar) alongside CI/CD pipelines and DevSecOps practices (automated builds, testing, secure integration workflows).
• The ability to obtain and maintain a U.S. government issued Secret security clearance is required. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.

Qualifications We Prefer

• Active and transferable U.S. government issued Secret security clearance.
• Experience with container technologies (Docker/Podman) including container security best practices
• Understanding of Linux OS security, SELinux/AppArmor, or secure configuration hardening
• Experience with application level security concepts (secure coding, vulnerability mitigation, dependency scanning)
• Familiarity with CMake/Conan/Artifactory workflows
• Knowledge of NVIDIA GPU drivers or CUDA
• Experience with IPMI, BIT development, or hardware/software integration
• Experience with embedded Linux platforms (x86_64, aarch64) and real time kernels (RedHawk)
• Experience with kernel level development, device drivers, or KO modules
• Familiarity with PCIe (MMIO, MSI X, DMA) and common I/O interfaces (UART, SPI/BPI)
• Experience with Ethernet, IP/TCP/UDP, or network interface development
• Exposure to MIL STD 1553, Camera Link, or CoaXPress
• Experience with Yocto, Petalinux, DeviceTree, GRUB, or U Boot
• Familiarity with VPX/SOSA hardware architectures, SBCs, and EO/IR sensor systems

What We Offer

• Opportunity to work on mission critical systems that support national defense
• Collaborative engineering culture with strong technical mentorship
