From designing the most advanced air vehicle to designing aircraft that defies gravity, our engineers live on the cutting edge of technology. Never have the opportunities for a technical career been so limitless. 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., * 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) ## Description * Kernel & Driver Development * Design, implement, and maintain Linux device drivers (PCIe, UART, SPI, I²C, 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 ## Related Videos - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Using WebAssembly to run, extend, and secure your application](https://www.wearedevelopers.com/videos/652-using-webassembly-to-run-extend-and-secure-your-application) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [On developing smartphones on wheels](https://www.wearedevelopers.com/videos/258-on-developing-smartphones-on-wheels) - [Collaboration Quantified: Lessons from Open Source Developer Networks](https://www.wearedevelopers.com/videos/1422-collaboration-quantified-lessons-from-open-source-developer-networks) - [Car's are Technology on Wheels - Impact of Software and IT Competence in Automotive](https://www.wearedevelopers.com/videos/780-car-s-are-technology-on-wheels-impact-of-software-and-it-competence-in-automotive) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Now is the time for industrialized software development](https://www.wearedevelopers.com/magazine/601-now-is-the-time-for-industrialized-software-development) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology)
