This position is with the Core Processing Software team in Fort Worth, TX. This position requires a software engineer to use a wide application of technical principles, theories, and concepts in the software field to develop, integrate, and test software products for the F-35 program. You will be expected to lead in the design, development and integration of middleware software.
Software development experience including requirements analysis, high-level and detailed design, coding, test planning, unit-testing, and CSCI integration testing is desired.
You will be a member of a high-performing team and must be self-motivated with a strong work ethic, time-management, and interpersonal skills. You must have demonstrated effective pro-active communication skills as the position will require frequent inter-organizational and outside customer interactions.
Key Responsibilities
• Kernel & Driver Development
• Design, implement, and maintain Linux device drivers (PCIe, UART, SPI, IC, etc.) with hard real time guarantees.
• Implement and tune two level interrupt handling (top half/bottom half, threaded IRQs) to achieve microsecond latency.
• Integrate and configure PREEMPT_RT or other real time patches; validate deterministic behavior with kernel tracing tools.
• Real Time Debugging & Performance Analysis
• Perform kernel level debugging (KGDB, ftrace, perf, SystemTap) and use LTTng for low overhead tracing of interrupt paths and task scheduling.
• Conduct latency/jitter analysis, root cause investigations, and apply mitigations such as IRQ affinity, priority inheritance, and priority ceiling protocols.
• Precision Time Protocol (PTP)
• Implement, configure, and troubleshoot PTP (IEEE 1588) on Linux platforms.
• Work with ptp4l, phc2sys, and related utilities to achieve sub microsecond clock synchronization for time critical applications.
• Build & CI/CD Infrastructure
• Maintain Buildroot configurations for cross compiling the full Linux stack (kernel, root filesystem, bootloader) for target hardware.
• Maintain CI pipelines (GitLab CI, Jenkins, etc.) that automate builds, driver unit tests, and generation of firmware/software artifacts.
• Collaboration & Documentation
• Partner with hardware designers to develop device drivers, collaborate with system designers to develop requirements for real-time safety-critical applications.
• Produce clear technical documentation, design reviews, and support guides for internal teams and external partners
Basic Qualifications- Development on Linux with hard real time extensions (PREEMPT_RT). Specifically developing multi-threaded real-time POSIX applications using real time scheduling policies (SCHED_FIFO, SCHED_RR) in user space, and developing device drivers in kernel space.
- Strong C/C++ skills, x86 and ARM assembly, and familiarity with Python/Bash for scripting and automation
- Debug proficiency with GDB/KGDB, LTTng, strace, dmesg, ftrace, perf, and hardware debug interfaces (JTAG, UART)
- Expertise with Buildroot for creating custom root filesystems and toolchains
- Experience with PTP (IEEE 1588) and implementations such as ptp4l, phc2sys, and related management tools
- Ability to obtain DoD secret clearance
- Bachelor's degree or above from an accredited college in a software related major, or equivalent experience/combined educatio
Desired Skills• Containerization & Orchestration - Experience packaging real time workloads with Podman (tar ball export/import) and deploying lightweight orchestration using K3s or pure Podman in air gapped environments. Ability to debug containers on target hardware (e.g., podman exec, nsenter, gdbserver, strace, in container LTTng tracing).
• Understanding of namespaces, capes, and cgroups. Knowledge of seccomp (possibly BTF JIT) or AppArmor profiles for sandboxing containers and processes (as an alternative to SELinux).
• Familiarity with the Yocto Project as an analogue for understanding Buildroot
• Understanding of PCIe SR IOV, DMA, and memory mapped I/O for high throughput data paths
• Experience with LynxSecure and the LynxOS operating system
• Contributions to open source kernel, driver, or tracing projects
• Familiar with File I/O
• Familiar with Data Encryption\Decryption
• Familiar with File Information Broker
• Agile Software Development
• Experience with JSF architecture
• Complete software lifecycle development process and test philosophies
• Experience with software pipelines
• Experience using the Python scripting language
• Atlassian Collaboration Tools (JIRA)
